This invention does not impose any special limitations on the specific location or arrangement of the functional module within the eyeglass frame; it can be arranged according to the technical common sense of those skilled in the art, as long as it allows the functional module to exist stably within the eyeglass frame.

[0061] In this invention, the transparent organic photovoltaic (OLED) modules in the self-powered system integrating transparent organic photovoltaics are preferably integrated into the edge area of ​​the smart glasses lens and / or the surface of the frame. The integration method is preferably a hybrid integration method, more preferably a ring-shaped arrangement at the lens edge and an arrangement on the temple. The ring width of the ring-shaped arrangement at the lens edge is preferably 2-8 mm, more preferably 3-7 mm, and even more preferably 4-6 mm. The temple arrangement is preferably a method of fitting the transparent organic photovoltaic module to the curved surface of the temple. The transparent organic photovoltaic modules in the ring-shaped arrangement at the lens edge and the temple arrangement are preferably connected in parallel and then connected to the energy management system. In this invention, the transparent organic photovoltaic module in the ring-shaped arrangement at the lens edge is the core power supply unit, and the transparent organic photovoltaic module in the temple arrangement is an auxiliary power supply unit. This arrangement method can increase the contact area between the transparent organic photovoltaic module and the light, thereby improving power generation efficiency. Simultaneously, the transparent organic photovoltaic modules are distributed in a ring shape at the lens edge, without obstructing the central field of view of the lens. After encapsulation, the overall thickness of the temple is moderate, ensuring wearing comfort.

[0062] In this invention, the energy management system of the integrated transparent organic photovoltaic self-powered system is preferably connected to the transparent organic photovoltaic modules and functional modules. By connecting the energy management system and functional modules, this invention can dynamically adjust the operating parameters of the functional modules based on the real-time power generation of the transparent organic photovoltaic modules. It can also dynamically adjust the brightness of the display module or the sampling frequency of the sensor module within the functional modules based on the power generation, prioritizing power supply to the core functions of the display module when power generation is insufficient.

[0063] In this invention, the transparent organic photovoltaic (PV) module and auxiliary PV module in the self-powered system integrating transparent organic photovoltaics absorb light energy and convert it into direct current (DC). The power conversion module in the energy management system boosts the DC output from the PV module and converts it into stable DC to match the operating voltage of the functional modules in the smart glasses. Simultaneously, the energy management controller monitors the total power generation, the remaining power of the energy storage unit, and the operating status of the smart glasses in real time. When the power generation is greater than or equal to the real-time power consumption of the functional modules, the transparent organic PV module directly powers the functional modules and simultaneously charges the energy storage unit. When the power generation is less than the real-time power consumption of the functional modules, the energy storage unit and the transparent organic PV module work together to supply power. The energy management system feeds back the power generation information to the microprocessor, which dynamically adjusts the operating parameters of the functional modules to optimize energy consumption.

[0064] This invention breaks through the bottlenecks of short battery life and heavy weight of traditional smart glasses by using a flexible and transparent integrated design of transparent organic photovoltaic modules. At the same time, it further optimizes energy consumption through an energy management method that dynamically adjusts the working parameters of the power generation function module. It is suitable for multiple scenarios such as AR near-eye display and outdoor adaptive dimming, and has the advantages of lightweight, long battery life and good visual experience.

[0072] Application Example 2 The self-powered system integrating transparent organic photovoltaics provided in Example 2 is applied to an outdoor sightseeing elevator: The outdoor sightseeing elevator consists of an elevator car, a transparent viewing curtain wall, an elevator drive system, and a car function module. The car's functional modules consist of a car lighting system, a ventilation system, a display and interaction module, and an emergency alarm module; the display and interaction module is a transparent display panel; the display and interaction module is integrated into the outdoor sightseeing elevator. Figure 2 (within the yellow area) In the self-powered system of integrated transparent organic photovoltaics, the transparent organic photovoltaic modules are integrated onto the outer surface of the transparent viewing curtain wall; the length and width of a single transparent organic photovoltaic module are as follows: Figure 2 As shown; the spacing between adjacent components in the transparent organic photovoltaic module is 10mm; the connecting wires of the transparent organic photovoltaic module are located within the gap, and the gap between adjacent components is filled with weather-resistant sealant; In the self-powered system integrating transparent organic photovoltaics, the energy management controller of the energy management system is electrically connected to the transparent organic photovoltaic modules, the elevator drive system, and the car function module. The auxiliary photovoltaic module is installed at the top of the elevator shaft of the external light elevator; preferably, the auxiliary photovoltaic module is connected in parallel with the transparent organic photovoltaic module and then connected to the energy management system.

[0073] A physical image of the outdoor sightseeing elevator provided in Application Example 2 of this invention is shown below. Figure 2 As shown; a schematic diagram of the outdoor sightseeing elevator provided in Application Example 2 of the present invention is shown. Figure 3 As shown. By Figure 2 and Figure 3 It can be seen that the transparent organic photovoltaic modules in the self-powered system are mainly concentrated on the surface of the transparent viewing curtain wall of the outdoor sightseeing elevator; the auxiliary photovoltaic modules are mainly concentrated on the top of the outdoor sightseeing elevator, while the energy management system and wires are hidden in the gaps of the outdoor sightseeing elevator, which will not affect the appearance of the outdoor sightseeing elevator or its light transmittance.

[0074] Test Example 2 The length and width of one side of the curtain wall are 3m and 4m, which can accommodate 56 batteries of 30cm and 40cm each. Area of ​​a single piece: 0.3m × 0.4m = 0.12m 2 , Total paving area for 3 layers: 56 pieces × 0.12m 2 ×3 floors = 20.16m 2 , Set at standard high intensity light 1000W / m 2 Down Pmax = Total area × Standard irradiance × Module conversion efficiency × System overall efficiency = 20.16 × 1000 × 7% × 0.85 = 1199.5W Daily power generation (conservatively estimated based on the national average effective sunshine duration of 4 hours / day from 10:00 to 14:00) = 1199.5W × 4h = 4.8kWh A = Photovoltaic power supply directly to the load (consumed immediately during the day, without going through batteries). B = The amount of electricity that the photovoltaic system charges into the energy storage battery (charged into the battery and stored for use at night). D = the amount of electricity released by the energy storage battery. Egrid = Electricity replenished by the power grid. Lithium battery charge / discharge cycle efficiency: 90%, i.e., D = B × 0.90. The elevator and car's average daily total energy consumption is 11.6 kWh (drive 9.5 + function 2.1), with a nighttime load of 11.6 kWh × 30% = 3.48 kWh. Based on the actual operation pattern of the elevator during the day, the photovoltaic direct supply load A is set at 2.6kWh (during the elevator operation period from 8:00 to 17:00 during the day, photovoltaic power is given priority to direct supply). The amount of electricity charged into the battery, B = E_total - A = 4.8 - 2.6 = 2.2 kWh. The battery can release a charge D = B × 0.90 = 2.2 × 0.90 = 1.98 kWh. The grid-supplemented electricity (Egrid) = Total load - AD = 11.6 - 2.6 - 1.98 = 7.02 kWh. The actual total electricity contribution from photovoltaic power generation = A + D = 2.6 + 1.98 = 4.58 kWh. The photovoltaic self-sufficiency rate on that day was 4.58 / 11.6 = 39.5%. For a 12V 20Ah (15 kWh) battery capacity, with a SOC of 35%, the corresponding energy capacity is 15kWh × 35% = 5.25kWh. To charge the battery from 35% in the morning to the system's set "full charge protection threshold" of 85% (12.75kWh of battery capacity). The required net charge is: 12.75 - 5.25 = 7.5 kWh. The average daily net increase in battery capacity = charging amount 2.2 - discharging amount 1.98 = 0.22 kWh. Therefore, the cumulative number of consecutive sunny days required to reach full charge is approximately 7.5 / 0.22 ≈ 34 days (22 consecutive days of equally sunny weather). Usage time after full charge (reaching 85% SOC): Assuming the battery reaches 85% SOC (12.75kWh) after a series of sunny days, in pure standby mode (power consumption approximately 80W). Battery life = 12.75kWh / 0.08kW = 159.4h (approximately 6.6 days). Nighttime low-frequency operation mode (elevator operates intermittently, with an average power consumption of approximately 0.35kW). Battery life = 12.75 / 0.35 ≈ 36.4 hours.

[0075] It can be seen that the self-powered system of integrated transparent organic photovoltaic provided in Embodiment 2 of the present invention has a long battery life when used in outdoor sightseeing elevators.
