Polyoxometalate (POM) can act as an electron\u2010transfer medium to decrease electron recombination in a photoelectric device owing to its excellent oxidation\/reduction properties and thermostability. A POM\/TiO<jats:sub>2<\/jats:sub> electronic interface layer prepared by a simple layer\u2010by\u2010layer self\u2010assembly method was added between fluorine\u2010doped tin oxide (FTO) and mesoporous TiO<jats:sub>2<\/jats:sub> in the photoanode of QDSCs, and the effect on the photovoltaic performance was systematically investigated. Photovoltaic experimental results and the electron transmission mechanism show that the POM\/TiO<jats:sub>2<\/jats:sub> electronic interface layer in the QDSCs can clearly suppress electron recombination, increase the electron lifetime, and result in smoother electron transmission. In summary, the best conversion efficiency of QDSCs with POM\/TiO<jats:sub>2<\/jats:sub> electronic interface layers increases to 8.02\u2009%, which is an improvement of 25.1\u2009% compared with QDSCs without POM\/TiO<jats:sub>2<\/jats:sub>. This work first builds an electron\u2010transfer bridge between FTO and the quantum dot sensitizer and paves the way for further improved efficiency of QDSCs.<\/jats:p>","DOI":"10.1002\/cssc.201700764","type":"journal-article","created":{"date-parts":[[2017,5,23]],"date-time":"2017-05-23T20:52:08Z","timestamp":1495572728000},"page":"2945-2954","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["A Strategy to Enhance the Efficiency of Quantum Dot\u2010Sensitized Solar Cells by Decreasing Electron Recombination with Polyoxometalate\/TiO<sub>2<\/sub> as the Electronic Interface Layer"],"prefix":"10.1002","volume":"10","author":[{"given":"Li","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Chemistry Northeast Normal University  Changchun 130024 P.R.
