Description

technical field [0001] The invention belongs to the field of solar photovoltaics, and in particular relates to a solar photovoltaic module. Background technique [0002] The most basic components of solar photovoltaic power generation are solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. A solar panel composed of one or more solar cells is called a photovoltaic module, or a solar cell module. A solar cell module is a device that converts solar energy into electrical energy. It has various installation forms, is safe and pollution-free, and is inexhaustible. Inexhaustible advantages, so it has been vigorously developed. The quality of crystalline silicon materials plays a vital role in the efficiency of solar cells. The surface defect density of crystalline silicon substrate materials is very high, such as a large number of dangling bonds, impurities, and broken bonds, etc., resulting in a greatly reduced mino...

AI Technical Summary

Problems solved by technology

The quality of crystalline silicon materials plays a vital role in the efficiency of solar cells. The surface defect density of crystalline silicon substrate materials is very high, such as a large number of dangling bonds, impurities, and broken bonds, etc., resulting in a greatly reduced minority carrier lifetime on the silicon wafer surface and a relatively low recombination rate. Low

There are problems such as complex structure, poor reliability, low light utilization rate, and difficulty in heat dissipation during power generation
