Zusammenfassung

Two-component silicone encapsulation materials show a higher transmission in the short wavelength region compared to EVA (ethylene vinyl acetate) encapsulation material. This property leads to an enhanced blue response of the encapsulated solar cells and therefore an increase in Jsc (short circuit current density) is expected. Selective emitter and homogeneous emitter solar cells have been encapsulated with silicone materials as well as with EVA, and the IQE (internal quantum efficiency) of all cells before and after encapsulation was determined. A significant gain in IQE for wavelengths below 380 nm was observed for cells encapsulated with silicone compared to those with EVA. We estimate that that the improved blue response of the cells encapsulated with silicone results in a possible gain in Jsc of up to 1.3 % for the selective emitter cells.
