Organic solar cells are solar cells with organic materials as the core part. They mainly use photosensitive organics as semiconductor materials to generate voltage and form current through the photovoltaic effect to achieve the effect of solar power generation. The first organic photoelectric conversion device was prepared by Kearns and Calvin in 1958. Its main […]

In order to let more people have a better understanding of the solar photovoltaic power generation system, the following will introduce the knowledge of photovoltaic modules.
What are the types of thin film modules?
①Silicon-based thin film moduleSilicon-based thin film batteries include amorphous silicon thin film batteries, microcrystalline silicon thin film batteries, and polycrystalline silicon thin film batteries. At present, amorphous silicon thin film battery products are important in the market. The band gap of amorphous silicon is 1.7eV, and p-type or n-type a-Si can be obtained by doping […]
What is a silicon-based thin film module?
(1) Polysilicon thin film modulesIn order to save materials and improve economy, people have been depositing polysilicon films on cheap substrates since the mid-1970s, but the grown silicon film grains are too small to make valuable solar cells. At present, the preparation of polycrystalline silicon thin film batteries mostly uses chemical vapor deposition methods, including […]
What is a polysilicon solar module?
At present, most of the polycrystalline silicon materials used in solar cells are aggregates containing a large number of single crystal particles, or are made by melting and casting waste single crystal silicon materials and metallurgical grade silicon materials. The process is to select polycrystalline bulk material or monocrystalline silicon head and tail material with […]
What is a monocrystalline silicon module?
Monocrystalline silicon modules are currently the fastest-developed photovoltaic modules and have been widely used in space and on the ground. The solar cells in the monocrystalline silicon module use high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.999%. At present, the monocrystalline silicon modules used on the ground use solar-grade monocrystalline […]
