The nanostructure simultaneously offers a low degree of charge recombination and a direct pathway for electron transport. Without correcting 64.5% loss of incident photons through light absorption and scattering by the F\u2010doped tin oxide (FTO) glass, the incident power conversion efficiency reaches 14.7% at 330 nm, more than twice as large as the nanocrystalline TiO<jats:sub>2<\/jats:sub> (TiO<jats:sub>2<\/jats:sub> NC, 6.4%)\u2010film based PECC. By connecting a PECC to an ammeter, the intensity of UV light is quantified using the output short\u2010circuit photocurrent density (<jats:italic>J<\/jats:italic><jats:sub>sc<\/jats:sub>) without a power source. Under UV irradiation, the self\u2010powered UV photodetector exhibits a high responsivity of 0.6 A\/W, a high on\/off ratio of 4550, a rise time of 0.03 s and a decay time of 0.01 s for <jats:italic>J<\/jats:italic><jats:sub>sc<\/jats:sub> signal. The excellent performance of the B\u2010SnO<jats:sub>2<\/jats:sub> NF\u2010based PECC type self\u2010powered photodetector will enable significant advancements for next\u2010generation photodetection and photosensing applications.<\/jats:p>","DOI":"10.1002\/smll.201202408","type":"journal-article","created":{"date-parts":[[2012,12,22]],"date-time":"2012-12-22T04:56:46Z","timestamp":1356152206000},"page":"2005-2011","source":"Crossref","is-referenced-by-count":216,"title":["High\u2010Performance Photoelectrochemical\u2010Type Self\u2010Powered UV Photodetector Using Epitaxial TiO<sub>2<\/sub>\/SnO<sub>2<\/sub> Branched Heterojunction Nanostructure"],"prefix":"10.1002","volume":"9","author":[{"given":"Xiaodong","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caitian","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huigao","family":"Duan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bingan","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youqing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lulu","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenxing","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojun","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erqing","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,12,21]]},"reference":[{"key":"e_1_2_7_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/nbt920"},{"key":"e_1_2_7_1_3","doi-asserted-by":"publisher","DOI":"10.1126\/science.1176706"},{"key":"e_1_2_7_1_4","first-page":"29","volume":"20","author":"Ettenberg M.","year":"2005","journal-title":"Adv.
