Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

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.
