Abstract
A thin film solar cell including a substrate, a first conductive layer, a photoelectric conversion layer, a second conductive layer and a passivation layer is provided. The first conductive layer disposed on the substrate has a plurality of first openings, so as to divide the first conductive layer into bottom electrodes of a plurality of photovoltaic elements. The photoelectric conversion layer disposed on the first conductive layer has a plurality of second openings. The second conductive layer is disposed on the photoelectric conversion layer and electrically connected to the first conductive layer through the second openings. The passivation layer is disposed on the sidewall of the photoelectric conversion layer, so that the second conductive layer in the second openings is electrically isolated from the photoelectric conversion layer. A manufacturing method of the thin film solar cell is also provided.
