(54)	TANDEM SOLAR CELL AND TANDEM SOLAR CELL MODULE COMPRISING THE SAME

(57) The present disclosure relates to a tandem solar cell, a tandem solar cell module comprising the tandem solar cell, and a method for manufacturing the same. More specifically, the present disclosure relates to a monolithic tandem solar cell comprising a perovskite solar cell laminated on a front surface of a crystalline silicon solar cell, and a method for manufacturing the same.
According to the present disclosure, a nano-electrode structure can be patterned on a front surface of a front transparent electrode of a solar cell in which a crystalline silicon solar cell and a perovskite solar cell are bonded via a junction layer, such that the optical path of the sunlight incident on the solar cell through the nano-electrode structure can be increased to improve the utilization rate of the light.
