Hybrid solar cells with an energy conversion efficiency of 1.04% were fabricated by spin-coating poly(3-hexylthiophene) (P3HT) polymer onto vertically aligned n-type GaAs nanowire arrays synthesized by molecular beam epitaxy. Experimental parameters such as the P3HT solvent mixing ratio of chlorobenzene to dichlorobenzene and nanowire surface etching were studied with a view to improving the energy conversion efficiency.
