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 [].

Photovoltaic Cells
There are two main types of solar panel – one is the solar thermal panel which heats a moving fluid directly, and the other is the photovoltaic panel which generates electricity. They both use the same energy source – sunlight – but change this into different energy forms: heat energy in the case of solar thermal panels, and electrical energy in the case of photovoltaic panels.
