Introduction. The function of a solar cell, as shown in Figure 1, is to convert radiated light from the sun into electricity. Another commonly used na me is photovoltaic (PV) derived from the Greek words "phos" and "volt" meaning light and electrical voltage respectively [1]. In 1953, the first person to produce a silicon solar cell was a Bell Laboratories physicist by the name of ...
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 energy is free from noise and environmental pollution. It could be used to replace non-renewable sources such as fossil fuels, which are in limited supply and have negative environmental impacts. The first generation of solar cells was made from crystalline silicon. They were relatively efficient, however very expensive because they require a lot of energy to purify …
Basic Physics of Solar Cells. A solar cell operates on the principles of a p-n junction, similar to a diode but with a larger area.
