13. First Generation Solar Cells: Disadvantages:cost effectiveness Silicon being an indirect band gap material has a low light absorption coefficient. Such a property of silicon requires larger thickness of material for better optical absorption. Thicker material films when used in the device, demand longer charge diffusion lengths which put a constraint on the quality of the material.
In a photovoltaic device, there is a built-in asymmetry (due to doping) which pulls the excited electrons away before they can relax, and feeds them to an external circuit. The extra energy of the excited electrons generates a potential difference or electron motive force (e.m.f.).

Solar energy is a form of energy which is used in power cookers, water heaters etc. The primary disadvantage of solar power is that it cannot be produced in the absence of sunlight. This limitation is overcome by the use of solar cells that convert solar energy into electrical energy. In this section, we will learn about the photovoltaic cell
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.
The solar cell is the basic building block of solar photovoltaics. The cell can be considered as a two terminal device which conducts like a diode in the dark and generates a photovoltage when charged by the sun. When the junction is illuminated, a net current flow takes place in an external lead connecting the p-type and n-type regions.
