Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight.
3.2.1 Absorption and Energy Conversion of a Photon. When light illuminates a solar cell, the semiconductor material absorbs photons; thereby, pairs of free electrons and holes are created (see Fig. 3.1).However, in order to be absorbed, the photon must have an energy E ph = hν (where h is Planck''s constant and ν the frequency of …
Comparison of the three phases have shown that anatase and rutile have the same photocurrent voltage response. On contrary, short-circuit current of anatase based solar cell is greater compared to the rutile based solar cell. The reason for this variation is that rutile has smaller surface area per unit volume [11]. In contrast, due to higher ...

A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, kn…
