Abstract: Provided is a perovskite solar cell including a substrate, a lower transparent electrode provided on the substrate, an upper transparent electrode provided on the lower transparent electrode, and a light absorption layer interposed between the lower transparent electrode and the upper transparent electrode, wherein the light absorption layer includes a perovskite material, and at least one of the lower transparent electrode or the upper transparent electrode includes a first color implementation layer, an intermediate layer, and a second color implementation layer, which are sequentially stacked, the first color implementation layer and the second color implementation layer each being a metal oxide layer containing a dopant.

Abstract: Provided is a bi-facial transparent solar cell including a first substrate and a second substrate disposed on the first substrate, a light absorbing layer disposed between the first substrate and the second substrate, a first transparent electrode disposed between the first substrate and the light absorbing layer, and a second transparent electrode disposed between the second substrate and the light absorbing layer. The first transparent electrode and the second transparent electrode may each transmit light having wavelengths different from each other.
