| Research Abstract |
The effect of the light irradiation on the electronic structure of a donor/acceptor(DA) heterojunction interface was investigated by using the photoelectron spectroscopy. Under the light irradiation, the photoelectron spectrum was shifted corresponds to the polarity of the photovoltage of the DA heterojunction photovoltaic cell. The shift of photoelectron spectrum was caused by the photo-generated holes(electrons) in the donor(acceptor) layer. The shift value was, however, smaller than the typical value of open-circuit voltage of the DA heterojunction photovoltaic cell. The present results imply that the development of an electromotive force in an organic photovoltaic cell is closely related to a presence of semipermeable membranes for the photo-generated charges in the photovoltaic cell.
