摘要： Hybrid optical layers of PMMA containing different concentrations of CdSe/ZnS core/shell semiconductor quantum dots were fabricated. Their absorption and luminescence showing quantum confinement effects are given. A frequency down-conversion is then obtained. The external quantum efficiency measurement performed on silicon solar cell with and without the down-conversion layers shows that the luminescence induces new charge generation. In addition, Finite Difference Time Domain (FDTD) simulation of organic solar cell shows that, added to the frequency conversion effect, one can expect to have an increase in light confinement when quantum dots are embedded in the active layer. ► Optical quality layers of PMMA containing CdSe/ZnS quantum dots were fabricated. ► Obtaining frequency down-conversion effect from quantum dots is applied to solar cell. ► Luminescence of quantum dots induces new charge generation in solar cell is verified. ► Both of frequency conversion effect and an increase in light confinement are expected. ► We propose core/shell quantum dots embedded in the active layer of organic solar cell. 出版者： Elsevier B.V 出版日期： 2013-10-01 出處： Solar Energy Materials and Solar Cells, 2013-10, Vol.117, p.652-656 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2012 Elsevier B.V. 版權： licence_http://creativecommons.org/publicdomain/zero 識別號： ISSN: 0927-0248 識別號： ISSN: 1879-3398 識別號： EISSN: 1879-3398 識別號： DOI: 10.1016/j.solmat.2012.12.005
