TL;DR: In this paper, an 18% efficient monolithic silicon/perovskite tandem solar cells were constructed by combining optical optimization of the device architecture including light trapping approaches. But the design of the tandem cell is limited by the photocurrent generated in the silicon bottom cell that is reduced due to reflectance losses.

TL;DR: These organic-inorganic perovskites exhibit radiation hardness and withstand proton doses that exceed the damage threshold of crystalline silicon by almost 3 orders of magnitude.

TL;DR: Large-area graphene grown by chemical vapor deposition as a highly transparent electrode in perovskite solar cells is implemented, leading to identical charge collection efficiencies and electrical performance of solar cells with a graphene-based contact reached those ofSolar cells with standard gold contacts.

TL;DR: The proposed degradation mechanisms reported in the literature are thoroughly reviewed and the microscopic mechanisms and their implications for solar cells are discussed.

TL;DR: In this paper, a monolithic perovskite/CIGSe tandem solar cell was proposed to increase the power conversion efficiency (PCE) of conventional single-junction photovoltaic devices.
