Monofacial modules capture light that falls on the front side of the module, and convert the solar energy to electricity. Bifacial modules can also capture the light that falls on the rear side of the module. For free standing bifacial modules, this results in a power output increase of 5 to 30% compared to monofacial modules. However, due to the heat generation by rear irradiance, this gain is partly lost. In this work, the effect of cell architecture (bifacial/monofacial) and module layout (bifacial/monofacial) on how much modules heat up under outdoor conditions is examined and the heat input mechanism from indoor measurements investigated. This is important because high temperature decreases the open circuit voltage (Voc) of the cell/module which means less power output...
