Solar Cells

1. Crystal silicon solar cell

[Summary] Solar cells are devices that use the principle of photoelectric conversion to convert the sun's radiant light into electrical energy through semiconductor materials. That is, the sunlight shines on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the built-in electric field of the p-n junction, the photogenerated holes flow to the p-region, and the photogenerated electrons flow to the n-region, and a current is generated after the circuit is turned on. In the process, SSRM/SMM, etc. are usually used to analyze the conductivity and carrier distribution of the doped region to confirm whether the electrical performance meets the standards.

2. Thin film solar cells

[Summary] Thin-film solar cells such as copper indium gallium selenide (CIGS) are known as the next generation of very promising new solar cells because of their significant characteristics such as low production cost, low pollution, no decline, good low light performance and high photoelectric efficiency. In terms of process, CAFM/SSRM is usually used to comprehensively evaluate their electrical distribution.
