g-C3N4nanosheetswork function engineeringEnhancement of open-circuit voltage ( V oc) is an effective way to improve power conversion efficiency (PCE) of the perovskite solar cells (PSCs). Theoretically, work function engineering of TiO 2 electron transport layer can reduce both the loss of V oc...
employed the UPS method to reveal the work function of acidified g-C3N4 (H1.5CN) and In2O3 [43]. As displayed in Fig. 3.9A, the UPS spectra reveal that the binding energy of the secondary electron cutoff edges for H1.5CN and In2O3 are 17.99 and 17.30 eV, respectively. Meanwhile, ...
Plasmon Low work function material Solvated electron Nitrogen photoreduction Visible light 1. Introduction Solvated electrons are smallest possible anions that can exists in nature [1], [2], [3]. Despite of “small” size and solvent cage (or water cage) stabilization, solvated electrons are very...
The ascorbic acid treatment increased the work function of MXene from 4.20 to 4.34eV, enhancing the Schottky barrier height of the heterojunction from 0.56 to 0.70eV. The devices exhibit excellent photoresponse performances, such as a responsivity of 0.133AW1 and a specific detectivity of 2.81×...
