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.
