A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …

Solar street light is a facility that uses solar energy to generate electricity and achieve lighting. Its working principle is mainly divided into two steps, that is, daytime photoelectric conversion and night lighting. During the day, solar panels receive sunlight and convert it into electricity, which is stored in a battery pack.

most solar cells, these membranes are formed by n- and p-type materials. A solar cell has to be designed such that the electrons and holes can reach the mem-branes before they recombine, i.e. the time it requires the charge carriers to reach the mem-branes must be shorter than their lifetime. This requirement limits the thickness of the absorber.
