TL;DR: The use of quasi-3D azetidinium lead iodide (AzPbI3) as a secondary layer on top of the primary 3D perovskite film that results in significant improvements in the photovoltaic parameters.
Journal ArticleDOI
Finely tuning electrolytes and photoanodes in aqueous solar cells by experimental design
Simone Galliano,Federico Bella,G. Piana,Giulia Giacona,Giulia Giacona,Guido Viscardi,Claudio Gerbaldi,Michael Grätzel,Claudia Barolo +8 more
TL;DR: In this article, the use of design of experiments as a useful chemometric technique for the concurrent investigation of a series of experimental factors that directly influence the proper operation of these photoelectrochemical cells was reported.
Journal ArticleDOI
Cyclic Water Cleavage by Visible Light: Drastic Improvement of Yield of H2 and O2 with Bifunctional Redox Catalysts†
TL;DR: The performance of a new cofunctional redox catalyst which achieves astonishingly high quantum yields in the water splitting process is described in this article, where the new catalyst contains Pt and RuO/sub 2/codeposited on a common carrier.
