    Improvement in the Power Conversion Efficiency of Bulk Heterojunction Photovoltaic Device via Thermal Postannealing of Subphthalocyanine:C70 Active Layer by Chih-Chien Lee, Shun-Wei Liu, Ching-Wen Cheng, Wei-Cheng Su, Chia-Chang Chou, Chun-Feng Lin, Chin-Ti Chen

    Published 2013-01-01
    “…The power conversion efficiency is improved from 4.5% to 5.5% due to the increase in short-circuit current density (JSC) from 8.8 to 12.7 mA/cm2 with the expense of decreased fill factor from 52% to 42%. From external quantum efficiency measurements, the spectral shape-independent enhancement over the entire spectrum suggests that the increased JSC mainly originates from improved charge collection efficiency. …”
