Problems solved by technology

However, the solar tracking device of this type of concentrating photovoltaic cell is a huge system with complex structure and high cost! Especially when the surrounding environment is harsh or in special weather, it is difficult to always ensure that the concentrating mirror and the battery are facing the sun, so that the solar energy cannot be fully utilized, resulting in unstable output power of the solar battery and a significant reduction in conversion efficiency

Abstract

A kind of solar battery light gathering device is used in the photospot photovoltatic directional device, it characterized in that it comprises a heat sink; a light canister which is subulate, and the alley end of the light canister is fixed to the heat sink; a solar battery which is fixed to the heat sink and is in the light canister; a collector lens whose axes is vertical with the light canister, and mounted above the big end of the light canister via bracket; a base board which is used to fix the heat sink.

Description

technical field [0001] The invention provides a device for directional light guiding in a concentrated photovoltaic system, in particular to a solar cell light concentrating device with a light guide tube. Background technique [0002] In today's increasingly prominent energy problems, solar power generation technology is one of the fastest-growing and most dynamic research fields in recent years. In recent decades, the first-generation crystalline silicon high-efficiency solar cells and the second-generation thin-film solar cells have made remarkable achievements. However, its high cost is still the main factor restricting the large-scale application of photovoltaic power generation. [0003] In order to reduce the cost of photovoltaic power generation, some developed countries in foreign countries are competing to develop concentrating photovoltaic cells, that is, by using cheap concentrating systems to concentrate sunlight to high-performance photovoltaic cells with a sm...
