Abstract

A method for manufacturing a solar cell including a photovoltaic layer, a first electrode layer, a second electrode layer, an insulating layer and a light-transparent conductive layer is provided. The photovoltaic layer has a first surface and a second surface. The first electrode layer having at least one gap is disposed on the first surface, wherein the at least one gap exposes a portion of the photovoltaic layer. The second electrode layer is disposed on the second surface. The insulating layer having a plurality of pores is located on the photovoltaic layer exposed by the at least one gap, wherein the holes expose a portion of the photovoltaic layer. The light-transparent conductive layer covers the insulating layer and is connected with the first electrode layer. The transparent electrode is connected with the photovoltaic layer through at least a part of the pores.
