Problems solved by technology

[0004] Conventional concentrating solar photovoltaic power generation systems increase the output power of solar cells by using lenses or mirrors to concentrate light onto a small area. This optical concentration will produce thermal effects that damage the power generation efficiency of solar cells, so efficient cooling is required. device, while the high cost of solar trackers also largely limits its application

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar photovoltaic power generation system and a preparation method. Background technique [0002] With the world's energy crisis and the aggravation of environmental pollution, using clean and renewable energy to replace traditional fossil energy to solve the problems of energy shortage and environmental pollution has become an inevitable trend of social, economic and technological development. A solar cell is a device that can effectively absorb solar energy and convert it into electrical energy. It is also the most important component in a solar photovoltaic power generation system. Therefore, solar cells have always been a hot spot in the research of clean and renewable energy. Recently, the National Energy Administration researched and drafted the "Thirteenth Five-Year Development Plan for Solar Energy Utilization (Draft for Comment)" on the basis of the dev...
