5. Construction of Solar Cell Solar cell (crystalline Silicon) consists of a n-type semiconductor (emitter) layer and p-type semiconductor layer (base). The two layers are sandwiched and hence there is formation of p-n junction. The surface is coated with anti-refection coating to avoid the loss of incident light energy due to reflection. A proper metal contacts are …

When the cell is cofired (in the next production step), the paste etches through the silicon nitride and silver contacts the underlying silicon to form the n-type contacts to the solar cell. This tutorial focuses on the silver screen printing process as the design of the screens is critical for the way the pattern is used to form the metal grid.
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
How a Solar Cell Works on the Principle Of Photovoltaic Effect. Solar cells turn sunlight into electricity through the photovoltaic effect. The key lies in the special properties of semiconductor materials. These materials are the foundation of solar energy systems today. Understanding Light Absorption and Electron Excitation
