Abstract: CulnSe2 is a promising light-absorbing material suitable for high-efficiency solar cells. It possesses many advantageous properties for solar applications: its band gap energy is at the red edge of the solar spectrum; it is direct band-gap semiconductor with correspondingly high absorption coefficients. The hybrid CulnSe2-P3HT material combining the advantages of the two materials will be widely applied in the photoelectric field. In this paper,the high performance hybrid photodetectors were fabricated and the influence of CulnSe2 nanocrystals concentration on the performance of the CulnSe2-P3HT hybrid photodetectors was investigated. As the CulnSe2 nanocrystals concentration was increased, the switching ratio reached a maximum value at a moderate CulnSe2 nanocrystals concentration,while the temporal response was faster.

Key words: CulnSe2, P3HT, hybrid material, switching ratio, temporal response
