TL;DR: In this article, the steady state anodic photocurrent for sensitized semiconductor electrodes, where the sensitizer is regenerated by a redox electrolyte, has been modeled taking into account the rate of light absorption by the sensitive sensor S, the electron injection from the excited state S∗ to the conduction band of the semiconductor, the decay rate of decay of S ∗, and the reductive regeneration of the resitizer by the redox ion by the regenerated ion S−.

TL;DR: This study provides a thorough understanding of the impact of inorganic cations on the properties and performance of highly efficient devices, and also highlights new strategies to fabricate efficient multiple-cation-based PSCs.

TL;DR: In this paper, the steady-state mass transport in a thin-layer cell configuration involving an electrochemically inactive mesoporous colloidal film was modeled and the limiting currents of an iodine containing electrolyte can be predicted, as a function of the film porosity.

TL;DR: In this article, a photoensitizer complex of formulae (Ia) MX3Lt or (Ib) MXYLt is defined, in which each X is a co-ligand independently selected from NCS?-, Cl-, Br-, I-, CN-, NCO-, H?2O, NCN2-, pyridine unsubstituted or substituted by at least one group selected from vinyl, primary, secondary or tertiary amine, OH and C?1-30? alkyl, preferably nCS?-?; and

TL;DR: In this article, a mesoscopic architecture as electron-selective contact for perovskite solar cells is introduced, where 40 nm sized TiO2 beads endowed with mesopores of a few nanometer diameters are used to achieve a very high fill factor of close to 80% a VOC of 1.14 V and a PCE up to 21% with negligible hysteresis.
