This article will introduce various types of new solar cells, as well as the principle and development of solar cells. When the sunlight shines on the semiconductor surface, the valence electrons of the atoms in the N and P regions of the semiconductor are excited by solar photons, and the energy beyond the forbidden band width Eg is obtained by optical irradiation. They form a photogenerated electric field opposite to the barrier in the vicinity of the p-n junction. Introduction History Working Principle Types of Solar Cells Benefits Application Disadvantages Final Thought Bibliography Further Reading 2 3. A small number of carriers in the photoexcited carriers can move to the P-N junction region and drifts to the opposite region through the P-N junction minority carrier pulling effect, and the opposite direction is formed opposite to the electric field of the P-N junction barrier Photoelectric field.
