Solar photovoltaic light filter

Abstract

The invention relates to a solar photovoltaic light filter, comprising a filtering body (1), a photovoltaic board (3) and a support (2); wherein the filtering body (1) and the photovoltaic board (3) are embedded and buckled on the support (2), the filtering body (1) is a glass triple prism with the vertical angle of 1.597-30 degrees, the vertical angle of the filtering body (1) is arranged at theparallel ray side of incident sunlight, and the parallel rays of sunlight enter the filtering body (1) from one side by selecting certain incident angle and the bottom surface of the filtering body (1) abuts on the photic surface of the photovoltaic board (3).

Description

technical field [0001] The invention relates to the technical field of solar power generation. Background technique [0002] As an inexhaustible green energy, how to effectively develop and utilize solar energy has always been one of the focuses of human research and exploration in the field of energy development and utilization. Many countries have been popularized and applied, but solar photoelectric conversion utilization technology and related products have not been effectively promoted and applied. The reasons are mainly in the following aspects: non-concentrating photovoltaic panels are used in dry seasons, which occupy the lighting area Large and expensive photovoltaic panels are required, resulting in high power generation costs; although the concentrating light photoelectric conversion system currently in use overcomes the above defects, the temperature of silicon photovoltaic panels rises rapidly due to the greatly increased light density. The temperature characte...

[0002] As an inexhaustible green energy, how to effectively develop and utilize solar energy has always been one of the focuses of human research and exploration in the field of energy development and utilization. Many countries have been popularized and applied, but solar photoelectric conversion utilization technology and related products have not been effectively promoted and applied. The reasons are mainly in the following aspects: non-concentrating photovoltaic panels are used in dry seasons, which occupy the lighting area Large and expensive photovoltaic panels are required, resulting in high power generation costs; although the concentrating light photoelectric conversion system currently in use overcomes the above defects, the temperature of silicon photovoltaic panels rises rapidly due to the greatly increased light density. The temperature characteristics of photovoltaic cells, the output current rises slowly with the increase of temperature, but the output voltage drops sharply and linearly, so the output power and conversion rate also decrease significantly with the increase of temperature, and greatly shorten the life of the photovoltaic cell, or even fail to work normally. ; The prior art uses a medium to circulate and cool the photovoltaic panel in the cavity of the photovoltaic panel base, which has a complex structure and high manufacturing cost
