<P>PROBLEM TO BE SOLVED: To provide a photovoltaic device which has high stability and reduces energy-potential loss on the interface between layers. <P>SOLUTION: The invented solar cell is composed of a substrate 1, an FTO layer 2, a shield TiO2 layer 3, a sensitized TiO2 layer 4 with a fluoride layer, a hole transport material (HTM) 5, a second fluoride layer 6 and an Au layer 7. It employs a vapor deposition layer of a fluoride and/or acetate, has higher stability than a conventional device, and reduces the energy-potential loss an the interface between layers. <P>COPYRIGHT: (C)2003,JPO |
