Abstract
The present disclosure relates to a tandem solar cell and a method of manufacturing the same, and more particularly, to a tandem solar cell having a perovskite solar cell stacked on and bonded to a silicon solar cell and a method of manufacturing the same. According to the present disclosure, a tandem solar cell embodied by using a homojunction silicon solar cell is provided with a first passivation pattern so that a part of an emitter layer under the first passivation pattern is exposed, thereby protecting, by the first passivation pattern, the emitter layer during high temperature firing for forming a second electrode, reducing surface defects of the emitter layer, and reducing a problem in that characteristics of the perovskite solar cell are degraded.
