Performance of bifacial MIS-inversion layer solar cells encapsulated in novel albedo collecting modules

It is the purpose of this work to demonstrate the first experimental results obtained on novel albedo collecting modules made with thin-silicon bifacially sensitive MIS inversion layer solar cells. The bifacial cells were fabricated on solar grade CZ-grown silicon substrates (0.5-1.7 ohm) of only 100 μm in thickness. By the application of a novel casting module technique, frameless bifacial flat plate modules, narrow in width and hence specially designed in order to efficiently collect the albedo, were fabricated. As an important result, outdoor measurements revealed that by using a simple arrangement of white back diffusers (i.e. a white-painted plate in parallel with the module), the output power of the elongated bifacial modules is increased by 33% as compared to monofacial modules. This consequently leads to a reduction of the Wp-costs for the albedo collecting modules
