Abstract

The invention discloses a device for enhancing photovoltaic power output under different time scales based on probability density fitting, and belongs to the technical field of photoelectricity. The device is composed of a light collecting plate (13), a light scattering plate (2), a solar cell panel (30) and a fixed frame (14) and is characterized in that the light scattering plate (2) is made of glass and comprises a light scattering channel (1) and a light scattering plate body (3), the light scattering channel (1) is a groove carved when light is scattered on the light scattering plate body (2) and provided with a reflecting silver layer (6), and the light scattering plate body (3) is arranged at the position, around the groove, below the reflecting silver layer (6); the light collecting plate (13) is made of glass, 5-15 light collecting hemispheres (11) are arranged on the upper surface of the light collecting plate (13), the inner walls of the upper half portions of hemisphere lower cavities (12) are plated with silver, mirror faces are formed, and the lower half portions of the hemisphere lower cavities (12) are transparent. The device for enhancing photovoltaic power output under different time scales based on probability density fitting is easy to manufacture, high in operability, low in cost and obvious in effect.

Description

technical field [0001] The invention relates to a device for enhancing photovoltaic output at different time scales based on probability density fitting, which belongs to the field of optoelectronic technology. Background technique [0002] At present, the use of solar panels can only be carried out when the sun is sufficient during the day, but in the morning and evening, because the light does not reach the solar panels, light absorption cannot be performed. Solar panels are generally used in the wild, neatly arranged together to form pieces to make full use of the deserted wilderness; or used on roofs and on top of street lamps. All these solar panels can absorb light efficiently only when the sun is directly shining, and their probability density is low, and the photovoltaic output varies greatly on different time scales. The photovoltaic output is very small. At night, after the sun goes down, the photovoltaic output tends to zero. How to overcome the low utilization ...

Problems solved by technology

How to overcome the low utilization efficiency of solar energy caused by known solar panels that can only use solar energy when the light is strong during the day, and improve the utilization efficiency of solar energy by solar panels has become an urgent problem to be solved? In nature, many animals are active at night. We call them nocturnal animals. These animals can generally see at night. The reason is that the structure of their eyes has a certain light-gathering ability, which can gather weak light together to achieve vision. object's purpose
