Summary / Abstract: For years, photovoltaic systems have been successfully installed on a large scale on open spaces as well as on (BAPV) and on buildings (BIPV). For the applications, PV modules in the classic glass-backsheet or glass-glass design are mostly used because their properties are well known. For BIPV and further on for automotive applications (VIPV) it makes sense to reduce the weight of the modules in order not to overload the building’s loadbearing capacity statics as well as for vehicles to minimize their energy consumption. One approach for weight reduction is by replacing glass with polymer materials. The light coupling on typical PV modules is largely optimized by means of an anti-reflective coating (ARC) on the front glass. This has not yet been done for polymer front sheets, but this paper will take the first step and characterize different lightweight approaches based on polymer front sheets with different solar cell types (SHJ, IBC) for their skewing behavior and then give an evaluation of the electrical yield for angle-dependent installation as well as for different locations.
