Abstract:
A photovoltaic cell having a structure including a first electrode layer, a first photovoltaic layer, an electrically conductive layer, a second photovoltaic layer and a second electrode layer that are successively laminatedwherein the first photovoltaic layer is a semiconductor film containing a first colorant, the second photovoltaic layer is a semiconductor film containing a second colorant, the first colorant and the second colorant being different from each other, so that the first photovoltaic layer and the second photovoltaic layer have different photocurrent action spectra, andwherein one of the semiconductor film of the first photovoltaic layer and the semiconductor film of the second photovoltaic layer is a p-type semiconductor film, and the other one is an n-type semiconductor film.
