Photoresponsive electrode and wet solar cell

摘要

A photoresponsive electrode for a wet solar cell wherein on a metal film having fixed thereon a photoresponsive molecule such as, for example, a porphyrin derivative, there is fixed by vapor deposition a light-irradiating portion such as a prism or optical fibers, and the metal film is irradiated with a light via the light-irradiating portion at about the resonance incident angle theta of inducing surface plasmon resonance in the interface between the metal film and the light-irradiating portion, and a wet solar cell using the photoresponsive electrode. In the photoresponsive electrode, the reflection of the incident light at the metal film can be restrained and the photoresponsive molecule can be efficiently excited even by sunlight of a low energy and the wet solar cell has a very excellent photoelectric transformation efficiency.
