Thin film solar cell and fabrication method thereof

Abstract

A thin film solar cell having an active area and a dead area is provided. The thin film solar cell includes a first substrate, a first conductive layer, an photovoltaic layer, a second conductive layer, a first passivation layer, and a second passivation layer. The first conducting layer, the photovoltaic layer, the second conductive layer, and the first passivation layer are respectively disposed on the first substrate, the first conductive layer, the photovoltaic layer, and the second conductive layer, and all of them are located in the active area. The second passivation layer is disposed on a peripheral of the photovoltaic layer and located in the dead area, so as to avoid the photovoltaic layer from contacting with moisture in air. A fabrication method of the thin film solar cell is also provided.
