Front Cover: The front cover shows that spin-coating a mixture solution of P3HT and PCBM on a cold substrate can increase the power conversion efficiency by 30-40% compared with the solar cells made by the conventional method. The image highlights the spin-coating on a cold substrate and the in situ generated desirable bulk heterojunction (BHJ). Further details can be found in the article by J. Y. Oh, T. I. Lee, J.-M. Myoung, U. Jeong,* and H. K. Baik* on page 1066.
