A solar cell is made of two types of semiconductors, called p-type and n-type silicon.

2. How does reverse bias affect the performance of a solar cell? When a solar cell is in reverse bias, the flow of current is reduced due to the depletion region between the p-type and n-type layers becoming wider. This leads to a decrease in the efficiency of the solar cell, as less energy is converted into electricity. 3.

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.
