Abstract: In the paper,two photosensitive dyes(thia-2'-cyanine dye and thiacyanine dye) were bound directly on monocrystalline silicon surface through chemical way respectively.Then the silicon wafer binding photosensitive dyes was examined by EPLP,LRS and XPS.The results show that the photosensitive dyes have been bound firmly to the monocrystalline silicon surface.And the spectral response curve of In/dye/n-Si(or p-Si) sandwich structure devices made of silicon wafers bound dye was determined.Compared with the spectral response curve of silicon p-n photocell of no covered antireflection coating it was found that there was a new response peak corresponding to the maximum absorption of photosensitive dye in the range of short wave,except the absorb peak at 650 nm.The short wave absorption of the silicon is increased and the spectral response range of the silicon is enlarged because of the binding of the dyes on the silicon surface.
