Paper Abstract

We demonstrate a polymer photodetector with spectral response from 300nm to 1450nm by using a narrow-band-gap semiconducting polymer blended with a fullerene derivative. Operating in room temperature, the polymer photodetectors exhibit detectivity greater than 1013Jones (1Jones =1cm Hz1/2/W) from the UV well into the near-infrared out to 1150nm and greater than 1012Jones from 1150nm to 1450nm. The linear dynamic range is over 100dB. To our knowledge, there is no inorganic material system (not even Si-Ge alloys) capable of such high performance photodetectivty over such a wide spectral range.
