Fast Electrochromic Switching with Nanocrystalline Oxide Semiconductor Films
TL;DR: In this article, forward biasing of transparent nanocryst is proposed to enhance the electrochromic process of lithium ion-contg. morphol. of the film plays a role in enhancing the electron accumulation and Li+ intercalation in anatase lattice.
Journal ArticleDOI
Structure-function relationships in unsymmetrical zinc phthalocyanines for dye-sensitized solar cells.

TL;DR: The photovoltaic data show that the nature of the spacer group plays a significant role in the electron injection from the photo-excited dye into the nanocrystalline TiO(2) semiconductor, the recombination rates and the efficiency of the cells.
Journal ArticleDOI
Interfacial electron transfer in colloidal metal and semiconductor dispersions and photodecomposition of water
