Although flash tests under standard test conditions yields lower power due to transmittance of the back sheet, bifacial modules are expected to outperform their monofacial equivalents in terms of yearly energy output in the field. Different transparent rear side materials have been compared. We compare flash tests for these bifacial modules at various incidence angles with and without a light scattering panel behind the modules. The results of an outdoor study comparing modules with transparent back sheet and modules with state-of-the-art AR coating on the front glass will be presented.
