Solar cell structure and manufacturing method thereof

A method for manufacturing a solar cell structure, comprising:

• providing a first type semiconductor layer;
• forming a second type semiconductor layer on the first type semiconductor layer so as to form a photovoltaic layer, wherein the photovoltaic layer has an upper surface, a lower surface and a plurality of side surfaces;
• forming an upper electrode on the upper surface of the photovoltaic layer so as to electrically connect the upper electrode with the second type semiconductor layer, wherein the second type semiconductor layer is located between the upper electrode and the first type semiconductor layer;
• forming a lower electrode on the lower surface of the photovoltaic layer so as to electrically connect the lower electrode with the first type semiconductor layer, wherein the first type semiconductor layer is located between the lower electrode and the second type semiconductor layer;
• and
• forming a passivation layer that covers at least one of the side surfaces so as to reduce a leakage current formed on the side surfaces.
