摘要： CulnSe2是具有重要应用前景的太阳能电池光吸收材料，具有带隙可调和吸收系数高等优点. CulnSe2纳米材料与P3HT共混形成的复合材料体系有望兼具无机和有机材料的优点，应用于光电领域. 本文利用CulnSe2纳米材料与P3HT共混，形成纳米复合材料，并由此构筑了具有高开关比的原理性光检测器件. 研究发现，两种材料的混合比例对器件的性能有明显影响. 随着CulnSe2纳米颗粒含量的增加，器件的开关比先增加后逐渐减小，而响应时间则一直减小.  

关键词: CulnSe2, P3HT, 有机-无机复合, 开关比, 响应时间

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
