Characteristics of ZnO-SnO2 Composite Nanofibers as a Photoanode in Dye-Sensitized Solar Cells

Composite materials are aimed to combine properties of their components to achieve a desired device functionality; however, synthesizing them in morphologies such as one-dimensional nanofibers is challenging. This article compares optical and electrical properties of ZnO–SnO2 composite nanofibers (C...
