Description

Technical Field

[0001] The utility model relates to the technical field of solar energy utilization, in particular to a wave-shaped solar cell panel. Background Art

[0002] With the increasing global demand for renewable energy, solar energy has garnered widespread attention as a clean energy source. Because solar energy is inexhaustible and pollution-free, it is an ideal energy source. A solar power generation system generally consists of solar panels, a solar controller, and batteries. Solar panels are the core and most valuable component of a solar power generation system. Their function is to convert solar energy into electricity, which is then either stored in batteries or used to power a load.

[0003] Existing photovoltaic solar panels, thanks to continuous technological breakthroughs, have achieved improved power generation efficiency and are a promising area for future solar photovoltaic power generation. Their lightness, relatively high power generation efficiency, and numerous advantages, such as flexibility and ductility, make them highly adaptable and versatile for widespread adoption. However, the impact of sunlight angle on photovoltaic power generation efficiency is an unavoidable issue. Furthermore, current solar panels are often flat and are used in one piece or pieced together, making them difficult to install and transport, hindering widespread use.

[0004] Existing solar panels have certain limitations in terms of photoelectric conversion efficiency, simple structure, and durability. Therefore, there is an urgent need for a solar panel that can improve efficiency, simplify the absorption structure, and increase the available space. Utility Model Content

[0005] The purpose of the utility model is to provide a solar cell panel structure with high photoelectric conversion efficiency and good durability.

[0006] In order to achieve the above-mentioned objectives, the present invention provides a wavy solar cell panel, comprising a supporting structure, on which a solar cell panel is provided, the supporting structure being wavy in shape, and the solar cell panel being arranged on the supporting structure; the solar cell panel comprises a photovoltaic material layer and an optical gain layer arranged on the photovoltaic material layer; the photovoltaic material layer sequentially comprises a single crystal silicon material layer, a copper indium gallium selenide material layer, and an organic photovoltaic material layer.

[0007] This utility model utilizes a multilayer photovoltaic material combination, combining single-crystal silicon, copper indium gallium selenide (CIGS), and organic photovoltaic materials to enhance photoelectric conversion efficiency and power generation capabilities under low-light conditions. By improving the structure and process of photovoltaic cells, the panels can generate more electricity per unit area. This effectively utilizes the multiple reflections and scattering effects of sunlight, increasing the absorbance of the photovoltaic material, thereby increasing photocurrent and improving power generation efficiency. Furthermore, the multilayer photovoltaic material design provides solar panels with greater stability and durability in the face of adverse weather and extreme climates, while ensuring power generation efficiency while reducing production costs and improving market competitiveness.

[0008] The optical gain layer employed in this utility model can better reflect and refract light, allowing more photons to be absorbed by the cell and converted into electrical energy. This optical gain layer optimizes light absorption and utilization, thereby improving photoelectric conversion efficiency. Furthermore, the presence of the optical gain layer improves the spectral response range of the solar cell, enabling it to more effectively utilize the different wavelengths of the solar spectrum, reducing light reflection losses, and further enhancing photoelectric conversion efficiency.

[0009] Preferably, the thickness of the solar cell panel is 150-500 microns.

[0010] Preferably, the solar cell panel is rectangular, and has an aspect ratio of 1-5:1.

[0011] According to a preferred embodiment, the width of the supporting structure is 100-800 cm.

[0012] Preferably, the wave height of the bearing structure is 50-400 cm.

[0013] Preferably, the ratio of the wave height to the wavelength of the bearing structure is 1:0.2-5.

[0014] When sunlight strikes the wavy solar panels provided by the present invention, the panels reflect a portion of the sunlight. The wavy solar panels then reflect this portion of sunlight back onto the opposing panels, achieving secondary or even multiple absorption of sunlight, significantly improving solar energy utilization. Furthermore, the inventors discovered that by limiting the wave height and wave height-to-wavelength ratio of the wavy support structure to specific, optimal ranges, sunlight can be utilized more scientifically and efficiently, improving photoelectric conversion efficiency.

[0015] Preferably, 20-50 solar panels are provided between two adjacent wave crests of the supporting structure.

[0016] Preferably, the solar panels are regularly arranged in a matrix on the supporting structure. By adopting a regular matrix arrangement, the area of solar panels per unit area of the supporting structure can be greatly increased, and the solar panels can absorb sunlight reflected from each other, thereby improving the utilization rate of solar energy.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] (1) The utility model uses a wave-shaped solar panel supporting structure and arranges the solar panels on the supporting structure. With the same area, the effective area for absorbing solar light is increased, the efficiency of absorbing solar energy and the ability to absorb solar energy from multiple viewing angles are improved.

[0019] (2) The present invention uses a multilayer photovoltaic material combination, combining single crystal silicon material, copper indium gallium selenide (CIGS) material and organic photovoltaic material to improve the photoelectric conversion efficiency and power generation capacity under low light conditions.

[0020] (3) The present invention also provides an optical gain layer on the photovoltaic material layer, which contains nanoparticles with a high refractive index, thereby increasing the transmittance of light and reducing the reflection loss of light. BRIEF DESCRIPTION OF THE DRAWINGS
