TL;DR: In this article, the authors show that planar perovskite solar cells using TiO2 are inherently limited due to conduction band misalignment and demonstrate, with a variety of characterization techniques, for the first time that SnO2 achieves a barrier-free energetic configuration, obtaining almost hysteresis-free power conversion efficiencies (PCEs).

TL;DR: In this paper, a simple solution-processed technological approach for depositing SnO2 layers in planar PSCs yields a high stabilized power conversion efficiency close to 21%, exhibiting stable performance under real operating conditions for over 60 hours.

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: A new synthetic method to grow Cu2O nanowire arrays on conductive fluorine-doped tin oxide substrates with well-controlled phase and excellent electronic and photonic properties is developed and an innovative blocking layer strategy is introduced to enable high performance.

TL;DR: Schreier et al. as discussed by the authors introduced atomic layer deposition of SnO2 on CuO nanowires as a means for changing the wide product distribution of CuO-derived CO2 reduction electrocatalysts to yield predominantly CO.
