After the encapsulation step, a c-Si solar module’s output is usually decreased, in comparison to its cells’ power, which is referred to as ‘power loss’. This paper focuses on the various factors that can impact power loss of solar modules, such as solar cell classification, encapsulation material, match of solar cells, the encapsulation process used, and so on. The conclusion indicates that power loss in solar modules can be significantly decreased with a resulting increment of a module’s output by appropriately optimizing those factors.
