Photodetectors with broad spectral response, from 300 nm to 1,100 nm, were fabricated using a narrow-band gap semiconducting polymer blended with a fullerene derivative. By using both an electron-blocking layer and a hole-blocking layer, the polymer photodetectors, operating at room temperature, exhibited calculated detectivities greater than 1013 cm Hz1\/2\/W over entire spectral range with linear dynamic range approximately 130 dB. The performance is comparable to or even better than Si photodetectors.<\/jats:p>","DOI":"10.3390\/s100706488","type":"journal-article","created":{"date-parts":[[2010,7,1]],"date-time":"2010-07-01T10:01:43Z","timestamp":1277978503000},"page":"6488-6496","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":97,"title":["Semiconducting Polymer Photodetectors with Electron and Hole Blocking Layers: High Detectivity in the Near-Infrared"],"prefix":"10.3390","volume":"10","author":[{"given":"Xiong","family":"Gong","sequence":"first","affiliation":[{"name":"Center for Polymers and Organic Solids, University of California Santa Barbara, Santa Barbara, CA 93106-5090, USA"}]},{"given":"Ming-Hong","family":"Tong","sequence":"additional","affiliation":[{"name":"Center for Polymers and Organic Solids, University of California Santa Barbara, Santa Barbara, CA 93106-5090, USA"}]},{"given":"Sung Heum","family":"Park","sequence":"additional","affiliation":[{"name":"Center for Polymers and Organic Solids, University of California Santa Barbara, Santa Barbara, CA 93106-5090, USA"}]},{"given":"Michelle","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of Washington, Seattle, WA 98195-4330, USA"}]},{"given":"Alex","family":"Jen","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of Washington, Seattle, WA 98195-4330, USA"}]},{"given":"Alan J.","family":"Heeger","sequence":"additional","affiliation":[{"name":"Center for Polymers and Organic Solids, University of California Santa Barbara, Santa Barbara, CA 93106-5090, USA"}]}],"member":"1968","published-online":{"date-parts":[[2010,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"091101\/1","DOI":"10.1063\/1.3099572","article-title":"Third-generation infrared photodetector arrays","volume":"105","author":"Rogalski","year":"2009","journal-title":"J Appl Phys"},{"key":"ref_2","first-page":"29","article-title":"A little night vision","volume":"20","author":"Ettenberg","year":"2005","journal-title":"Adv.
