Solar Cells: Transparent Conductive Oxide-Free Graphene-Based Perovskite Solar Cells with over 17% Efficiency (Adv. Energy Mater. 3/2016)
Patent
Perovskite based solar cells employing graphene as transparent conductive electrodes
TL;DR: In this article, a perovskite-based solar cell using graphene as a conductive transparent electrode was proposed, which achieved the highest efficiency through an appropriate energy band combination of graphene electrode/hole transporting layer/perovskitesite/electron transporting layer and metal electrode and can represent a conversion efficiency of 17% or more.
Patent
Perovskite solar battery and method for producing same
TL;DR: A perovskite solar cell of the present invention has a structure in which an electron transport layer including a fullerene or a Fullerene derivative is formed on a first electrode including a transparent conductive substrate and a blocking layer such as a BCP layer, is absent, achieving improved electron transporting properties as discussed by the authors.

TL;DR: In this paper, an ultrathin alkali-fluoride (AF) films was inserted between the tri-cation lead-iodide perovskite layer and both CTLs, which made use of both physical blocking and chemical-anchoring functionalities of the continuous, uniform and compact AF framework.
