Tandem solar cell, tandem solar cell module comprising the same, and method for manufacturing thereof

A solar cell module, comprising:

• a first substrate;
• a plurality of solar cells, two adjacent solar cells of the plurality of solar cells being electrically coupled to each other;
• and
• a second substrate,
• wherein each solar cell includes;
• a first solar cell,
• a second solar cell,
• an inter-layer positioned between the first solar cell and the second solar cell,
• a first transparent electrode that is coupled to a first surface of the first solar cell,
• a transparent electrode structure that is coupled to a first surface of the first transparent electrode and that includes a patterned transparent electrode,
• a first metal electrode positioned on the first transparent electrode, and
• a second electrode positioned on the second solar cell, and
• wherein the first substrate and the second substrate are positioned with a gap on the first solar cell and the second solar cell of the plurality of solar cells, respectively.

A method for manufacturing a solar cell, the method comprising:

• forming a crystalline silicon solar cell from a crystalline silicon substrate;
• forming an inter-layer on a surface of the crystalline silicon solar cell;
• forming a perovskite solar cell on a surface of the inter-layer;
• forming a transparent electrode on a surface of the perovskite solar cell;
• and
• patterning a transparent electrode structure on a surface of the transparent electrode.
