Especially, as surface recombination becomes more important in high efficiency solar cells, understanding and controlling recombination in the metal contact area are necessary. Recombination at the metal-silicon interface is a major cause of the drop in the open-circuit voltage (V oc) of a solar cell.
Recombination at the metal-silicon interface is a major cause of the drop in the open-circuit voltage (V oc) of a solar cell. Thus far, the study of electrodes in silicon solar cells has been largely aimed at reducing the series resistance, and few studies on recombination due to electrodes have been performed.
This study proposes a concise physics-based mathematical model that explains the effects of bulk and surface recombination on the photocurrent in various perovskite solar cells. Theoretical calculations and experimental results from several perovskite solar cells have been compared to validate the theoretical model.
Moreover, the optimum thickness of the p + -CZTS and p-CZTS absorber layers in p + pn CZTS dual layer structure is 1 and 1.5 µm, respectively. Finally, the total recombination current density is reduced to 2.05 mA/cm 2. Photovoltaic Solar energy is the most renewable, reliable, and accessible energy in the world.
