摘要

Hybrid solar cells based on poly(3-hexylthiophene) (P3HT) and Galium nitride (GaN) nanoparticle bulk heterojunction are fabricated and analyzed. The GaN nanocrystal is synthesized by means of a combination of sol-gel process with high temperature ammoniation using Ga(OC2H5) as a precursor. Their characteristics are determined by X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscopy. With the addition of GaN nanoparticle to P3HT, the device performance is greatly enhanced.
