A hybrid tandem solar cell based on hydrogenated amorphous silicon and dye-sensitized TiO2 film
Hydrogenated amorphous silicon film (a-Si:H) as top cell is introduced to dye-sensitized titanium dioxide nanocrystalline solar cell (DSSC) as bottom cell to assemble a hybrid tandem solar cell. The hybrid tandem solar cell fabricated with the thicknesses a-Si:H layer of 235 nm, ZnO/Pt interlayer of 100 nm and DSSC layer of 8.51 mu m achieves a photo-to-electric energy conversion efficiency of 8.31%, a short circuit current density of 10.61 mA.cm(-2) and an open-circuit voltage of 1.45 V under a simulated solar light irradiation of 100 mW.cm(-2).
