Inside Cover: Enhanced Performance of Quasi-Solid-State Dye-Sensitized Solar Cells by Branching the Linear Substituent in Sensitizers Based on Thieno[3,4- c]pyrrole-4,6-dione (Chem. Asian J. 1/2013).

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.
