Fabrication and encapsulation of perovskites sensitized solid state solar cells

Abstract

Perovskite-based solar cells are now emerging as an economically viable alternative for efficient photovoltaic energy harvesting. Using solution-based processing routes alone, devices with power conversion efficiencies exceeding 15% can be fabricated, in principle at a fraction of costs reported for other photovoltaic technologies. In these excitonic solar cells, the perovskites multifunctional nature allow these layers to behave as light absorber, electron conductor and hole transporting material, depending on the device architecture. In order to further optimize these devices and render them industrial feasible, device stability and encapsulation are of paramount importance. In the present contribution, the fabrication and encapsulation of perovskite-based solar cells will be presented and discussed. To the best of our knowledge this is the first study describing industry relevant encapsulation and device data.
