In this paper, a photovoltaic device with a solid Pn junction consisting of a Schottky barrier and a cyanine dye and an aluminum metal layer has been developed. Its open-circuit voltage exceeds 500 mV, its spectral absorption range covers the visible region, and the photoelectric conversion efficiency is higher than 0.1% battery. At the same time, some photovoltaic devices developed by thiocarbocyanine dyes with partial photovoltaic effect, such as merocyanine, multinuclear cyanine and bridged chain in Qijiachuan chain, have been explored as the possibility of laser detection element. At the output of 10 milliamperes Watt He-Ne laser excitation, can produce 320 millivolts of the photovoltaic effect, the quantum efficiency of 6%.
