摘要：

Construction of a semiconductor-dye heterostructure of the configuration n-TiO2/D-1/p-CuSCN/D-2/p-CuSCN/D-3/p-CuSCN (n-TiO2 is the nanocrystalline TiO2 film deposited on conducting glass, p-CuSCN = ultra-thin (similar to2 nm) layers of Cu(l) thiocyanate, p-CuSCN = thick layer of p-CuSCN, D-1=Fast Green, D-2 = Rhodamine 6G and D-3 Acridine Yellow) is described. It is found that this heterojunction generates photovoltaic response to light absorption by all the three dyes. The mechanism involved is suggested to be transfer of electrons to n-TiO2 and holes to p-CuSCN via tunneling. This technique could be a strategy to broaden the spectral response and enhance the efficiency of dye-sensitized solar cells. (C) 2004 Elsevier B.V. All rights reserved.
