Abstract :
High efficient solar cells are desired for the future clean power supply. Here, we report a method to improve the efficiency of the promising CNT–Si solar cells to about 10% by hydrogen peroxide (H2O2) doping. It forms hybrid solar cells consisting of numerous CNT–Si heterojunction cells and CNT–Si–H2O2 photoelectrochemical cells in parallel by dilute H2O2 doping. The quantum efficiency of the H2O2-doped solar cell is higher than that of the original cell because of the photoelectrochemical cells as well as the passivation surface.
