Abstract

original image

Highly porous amorphous Zn2SnO4 electrodes are prepared using electrospinning techniques and combined with organic or ruthenium dyes to fabricate dye-sensitized solar cells. As reported by Sung-Yeon Jang, Renaud Demadrille, Il-Doo Kim, and co-workers on page 3146, the devices based on 3-μm-thick electrodes and the organic dyes demonstrate significantly improved performances compared to those using the ruthenium complex. Using this approach, solar cells with power conversion efficiencies up to 3.7% are obtained.
