TL;DR: Simultaneous enhancement of open-circuit voltage, short-circuits current density, and fill factor in highly efficient polymer solar cells by incorporating an alcohol/water-soluble conjugated polymer as cathode interlayer is domonstrated.
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 domonstrated. 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.

TL;DR: In this article, the authors show that the recombination kinetics of polymer BHJ cells evolve from first-order recombination at short circuit to bimolecular recombinations at open circuit as a result of increasing the voltage-dependent charge carrier density in the cell.
Abstract: Recombination of photogenerated charge carriers in polymer bulk heterojunction (BHJ) solar cells reduces the short circuit current $({J}_{sc})$ and the fill factor (FF). Identifying the mechanism of recombination is, therefore, fundamentally important for increasing the power conversion efficiency. Light intensity and temperature-dependent current-voltage measurements on polymer BHJ cells made from a variety of different semiconducting polymers and fullerenes show that the recombination kinetics are voltage dependent and evolve from first-order recombination at short circuit to bimolecular recombination at open circuit as a result of increasing the voltage-dependent charge carrier density in the cell. The ``missing 0.3 V'' inferred from comparison of the band gaps of the bulk heterojunction materials and the measured open-circuit voltage at room-temperature results from the temperature dependence of the quasi-Fermi levels in the polymer and fullerene domains---a conclusion based on the fundamental statistics of fermions.

TL;DR: In this article, the authors proposed an active matrix substrate with a short circuit member having a convenient structure of high charge dispersiveness and functioning even after a packaging process, which substantially eliminates a leak current in a low voltage region.
Abstract: PROBLEM TO BE SOLVED: To obtain an active matrix substrate in which a TFT is protected effectively against static electricity by providing a short circuit member having a convenient structure of high charge dispersiveness and functioning even after a packaging process thereby substantially eliminating a leak current in a low voltage region. SOLUTION: The active matrix substrate comprises a substrate 1, a plurality of pixel electrodes formed on the substrate 1, a plurality of interconnect lines 2 and 6, a plurality of switching elements 20 each connecting at least one of the plurality of pixel electrodes electrically with at least one of the plurality of interconnect lines 2 and 6, and a short circuit member 3 having the characteristics of a varistor. The short circuit member 3 connects at least two adjacent interconnect lines 2 and 6 out of the plurality of interconnect lines 2 and 6. COPYRIGHT: (C)2004,JPO&NCIPI
