Effective Hydrogenation Strategies to Boost Efficiency over 20% for Crystalline Silicon Solar Cell with Al2O3/Cu2O Passivating Contact

In exploring p-type semiconductor Cu2O as a dopant-free hole-selective contact for crystalline Si solar cells, an ultra-thin H-Al2O3 prepared by atomic layer deposition utilizing H2/N2 mixture as carrier gas is adopted to improve the passivation quality. Finally, the device with a structure of p-Si/H-Al2O3/Cu2O/Pt/Ag dilivers a photoconversion efficiency of 20.35%.
