The photoresponse of semiconducting polymers can be enhanced significantly by photoinduced charge transfer (CT). The discovery of photoinduced CT in composites of conducting polymers and C 60 and its derivatives provided a molecular approach to high‐efficiency solar cells and high‐sensitivity photodetectors. Here the authors demonstrate the first large‐area image sensor made with such photosensitve composites. These image sensors have high photosensitivity, low dark current, large dynamic range, and can be fabricated by simple coating processes on flexible or curved substrates at low temperature.
