TL;DR: In this paper, the electron diffusion length (L) relative to film thickness is measured in a nanocrystalline, mesoporous TiO2 electrode during photochemical water splitting by two independent methods: (1) analyzing the ratio of incident photon conversion efficiency measured under back and front side illumination, and (2) analyzing transient photovoltage rise and decay measurements.

TL;DR: In this article, the authors show that homogeneous partial dye coverage cannot be achieved by short dyeing times or dilute dye solutions, due to the high sticking coefficient of the dyes on TiO2.

TL;DR: A numerical model of the dye sensitised solar cell (DSSC) is used to assess the importance of different loss pathways under various operational conditions and should provide a useful general framework for exploring new cell descriptions, architectures and other factors influencing device performance.

TL;DR: This work presents here a system, Ru-phthalocyanine sensitized TiO2, where slow electron injection (kinj ≈ 450 ns-1) and efficient electron injection are compatible owing to the long lifetime of the injecting state, theRu-phthalOCyanine triplet state.

TL;DR: In this article, a phenomenological study is presented of reverse bias behavior of halide perovskite solar cells and it is shown that reverse bias can lead to a partially recoverable loss in efficiency, primarily caused by a decrease in VOC.
