Abstract

original image

Dye-sensitized solar cells are regarded as a candidate for renewable energy source owing to their low cost, abundance of raw materials, ease of fabrication, and low energy consumption in the production process. In their Full Paper on page 168 ff., Gang Zhou, Zhong-Sheng Wang et al. introduced an ethyl group into a sensitizer with a linear hexyl group. With this branched 2-ethylhexyl group, the corresponding quasi-solid-state DSSC displayed a significantly reduced charge recombination rate, a longer electron lifetime, a higher photovoltage, and consequently an improved power conversion efficiency.
