Abstract
The present invention relates to an inorganic perovskite quantum dot-based solar cell capable of providing a significantly excellent photoelectric conversion efficiency compared to the related art by increasing a light absorption capacity even though a photoactive layer has a limited thickness. Specifically, the inorganic perovskite solar cell may include: an electron transport layer that is disposed on a transparent electrode; a photoactive layer having a flat structure that is disposed on the electron transport layer and includes inorganic perovskite quantum dots; an organic hole transport layer that is disposed on the photoactive layer and includes nanopatterns; and a back electrode that is disposed on the organic hole transport layer.
