How a Solar Cell Works
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …

Solar Cell Texturing: A Simplified Recipe
the simplified process uses 6 × 10 × 5 = 300 liters per process cycle with no recycling or 4 × 10 × 5 = 200 liters per process cycle for bath loads of approximately one hundred 156 × 156 mm2 silicon solar cell substrates. Thus, approximately a 33% to 55% savings of rinsing water with the simplified process can be obtained.

These procedures are applicable to a single PV solar cell, a sub-assembly of PV solar cells, or a PV module. They are applicable to single-junction mono-facial PV devices. For other device types, reference is made to the respective documents, in particular for multi-junction devices to IEC 60904-1-1 and for bifacial devices to IEC TS 60904-1-2.
Photovoltaic cells convert solar energy into electricity
Photovoltaic cells are devices that convert solar energy into electrical energy. When photons from light energy bump into the cell''s surface, they trigger an electric current moving electrons from one atom to another.. The use of this technology has increased rapidly in the last few years due to the need to replace the use of fossil …
