TLDR
A systematic analysis of the interplay among structural features, optoelectronic performance, and ionic movement behavior for FA0.83 MA0.17 Pb(I 0.83 Br0. 17 )3 PSCs is presented, which yield high power conversion efficiencies up to 20.8%.Abstract:
Hybrid organic-inorganic perovskite materials have risen up as leading components for light-harvesting applications. However, to date many questions are still open concerning the operation of perovskite solar cells (PSCs). A systematic analysis of the interplay among structural features, optoelectronic performance, and ionic movement behavior for FA0.83 MA0.17 Pb(I0.83 Br0.17 )3 PSCs is presented, which yield high power conversion efficiencies up to 20.8%.read more

Promises and challenges of perovskite solar cells
Juan-Pablo Correa-Baena,Juan-Pablo Correa-Baena,Michael Saliba,Tonio Buonassisi,Michael Grätzel,Antonio Abate,Wolfgang Tress,Anders Hagfeldt +7 more
TL;DR: Because photocurrents are near the theoretical maximum, the focus is on efforts to increase open-circuit voltage by means of improving charge-selective contacts and charge carrier lifetimes in perovskites via processes such as ion tailoring.

Not All That Glitters Is Gold: Metal-Migration-Induced Degradation in Perovskite Solar Cells.
Konrad Domanski,Juan-Pablo Correa-Baena,N. Mine,Mohammad Khaja Nazeeruddin,Antonio Abate,Michael Saliba,Wolfgang Tress,Anders Hagfeldt,Michael Grätzel +8 more
TL;DR: It is found that exposing PSCs to a temperature of 70 °C is enough to induce gold migration through the hole-transporting layer (HTL), spiro-MeOTAD, and into the perovskite material, which in turn severely affects the device performance metrics under working conditions.

TL;DR: It is shown that rapid light–induced free-radical polymerization at ambient temperature produces multifunctional fluorinated photopolymer coatings that confer luminescent and easy-cleaning features on the front side of the devices, while concurrently forming a strongly hydrophobic barrier toward environmental moisture on the back contact side.
