A Photoelectric Element Capable Of Converting Energy
Jun 04, 2018

Solar cells, also known as "solar chips" or "photocells," are optoelectronic semiconductor sheets that generate electricity directly from sunlight. As long as it is illuminated by light that satisfies certain illumination conditions, it can instantaneously output voltage and generate current in the presence of a loop. Physics is called Photovoltaic (PV), abbreviated as photovoltaic.

Solar cells are devices that directly convert light energy into electrical energy through photoelectric effects or photochemical effects. The crystalline silicon solar cell that works with the photoelectric effect is the mainstream, and the thin-film battery working with the photochemical effect is still in its infancy.

With the continuous development of the solar cell industry, competition in the internal industry is also intensifying, and mergers and acquisitions and capital operations between large-scale solar cell companies are becoming increasingly frequent. The domestic excellent solar cell manufacturers pay more and more attention to research on the industrial market, especially Industry development environment and product buyer's in-depth study. Because of this, a large number of domestic excellent solar battery brands have risen rapidly and have gradually become leaders in the solar cell industry.

A solar cell is a photoelectric element that can convert energy. Its basic structure is formed by joining P-type and N-type semiconductors. The most basic semiconductor material is "silicon", which is not conductive, but if semiconductors are doped with different impurities, they can be made into P-type and N-type semiconductors, and P-type semiconductors can be used as holes (P-type). The semiconductor loses a negatively charged electron, which can be regarded as a positive charge, and the potential difference between a free electron and an N-type semiconductor generates a current, so when the sunlight shines, the light energy will be in the silicon atom. The electrons are excited and convections of electrons and holes are generated. These electrons and holes are affected by the built-in potential and are attracted by the N-type and P-type semiconductors, respectively, and collected at both ends. At this point, if the external connection with electrodes, forming a loop, this is the principle of solar cell power generation.
