“Simultaneous enhancement of open-circuit voltage, short-circuit current density, and fill factor in polymer solar cells,” by Zhicai He, et al., Advanced Materials, 23(40): 4636, 25 October 2011.

Abstract: “Simultaneous enhancement of open-circuit voltage, short-circuit current density, and fill factor in highly efficient polymer solar cells by incorporating an alcohol/water-soluble conjugated polymer as cathode interlayer is demonstrated. When combined with a low-bandgap polymer PTB7 as the electron donor material, the power efficiency of the devices is improved to a certified 8.370%. Due to the drastic improvement in efficiency and easy utilization, this method opens new opportunities for PSCs from various material systems to improve towards 10% efficiency.”

This 2011 report from Advanced Materials was cited 53 times in current journal articles indexed by Thomson Reuters during July-August 2013. Thanks to that latest two-month total, the paper now ranks as the third-most-cited paper in chemistry/materials published in the last two years, excluding reviews. (The current #1 paper, the subject of a previous Weekly Byte, features many of the same authors.)
