"Mansoo Choi and co-workers demonstrate highly efficient transparent conductive oxide (TCO)-free inverted perovskite (CH3NH3PbI3) solar cells by using a graphene transparent electrode. Careful engineering of the interface between the graphene electrode and the hole transport layer enables the highest energy conversion efficiency of 17.1% among TCO-free solar cells to be obtained."
"Looks at energy production from renewable sources amidst the exceptionally challenging global economic crisis that the Mediterranean areas and other societies are currently experiencing, providing tools and measures that can be developed at the public, legislative, and market levels to counterbalance the lengthy payback times of energy efficiency measures"
"In this review, we shed light on one of the most versatile energy-conversion technologies: heterogeneous catalysts. We establish the integrity of structural tailoring in heterogeneous catalysts at different scales in the context of an emerging paradigm in materials science: catalytic nanoarchitectonics. Fundamental backgrounds of energy-conversion catalysis are first provided together with a perspective through state-of-the-art energy-conversion catalysis including catalytic exhaust remediation, fuel-cell electrocatalysis and photosynthesis of solar fuels. Finally, the future evolution of catalytic nanoarchitectonics is overviewed: possible combinations of heterogeneous catalysts, organic molecules and even enzymes to realize reaction-selective, highly efficient and long-life energy conversion technologies which will meet the challenge we face."
