Principle of thin and light solar cells
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics –. . A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes. A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor. We then. . When light photons reach the p-n junctionthrough the thin p-type layer, they supply enough energy to create multiple electron-hole pairs,. . In a typical solar cell, the is used to generate from sunlight. The light-absorbing or "active layer" of the solar cell is typically a material, meaning that there is a gap in its between the of localized around host and the conduction band of higher-energy electrons which are free to move throughout the material. For most semiconducting materials at room temperature, electrons which have not gai. [pdf]
