The Working Principle of a Solar Cell
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.
Solar Cell Structure
A solar cell is an electronic device which directly converts sunlight into electricity. Light shining on the solar cell produces both a current and a voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy state, and secondly, the movement of this ...
