Photovoltaic effect
The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy.The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.
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 [].
