Polymer: fullerene bulk heterojunction solar cells Jenny Nelson
The efficiency of solar cells made from a conjugated polymer blended with a fullerene derivative has risen from around 1 % to over 9 % in the last ten years, making organic photovoltaic technology a viable contender for commercialization. Jenny Nelson reviews developments in both materials science and device physics for organic photovoltaics.

Feeling blue? Blue phosphors for OLEDs Hungshin Fu, Yi-Ming Cheng, Pi-Tai Chou, and Yun Chi
Research on organic light-emitting diodes has been revitalized, partly due to the debut of OLED TVs. Chou and co-workers chronicle the development of blue phosphors in their laboratory, highlighting the importance of the interplay between chemistry and photophysics en route to true-blue phosphors.
Photomobile polymer materials: from nano to macro. Tomiki Ikeda and Toru Ube
A new class of polymer materials has been developed that can convert light energy directly into mechanical work, and show a variety of three-dimensional movements simply from
exposure to light. Ikeda and Ube take a look at the recent progress of work on this interesting class of polymer.
The emergence of memory in liquid crystals. Francesca Serra, Marco Buscaglia, and Tommaso Bellini
Liquid crystal displays rely on the molecular alignment of a liquid crystal under an applied electric field. Serra et al. discuss the development of hybrid materials formed from
liquid crystals that are capable of indefinitely retaining their alignment in the absence of a field.
