Abstract: Disclosed are a monolithic solar cell and a method of manufacturing the same. More particularly, the present invention provides a monolithic solar cell including a first solar cell formed by sequentially stacking an electrode, a silicon substrate, and an n-type emitter layer; a junction layer formed on the an n-type emitter layer; an interfacial layer formed on the junction layer; and a second solar cell including a perovskite layer and integrated onto the interfacial layer. The interfacial layer according to the present invention may be pyrolyzed and thus partially or completely lost during a monolithic solar cell manufacturing process. In addition, by providing an interfacial layer between the two cells constituting a monolithic solar cell according to the present invention, charge transfer and recombination characteristics between the two cells can be improved and thus a monolithic solar cell having significantly improved photoelectric conversion efficiency can be provided.
