Band Engineering in Core/Shell ZnTe/CdSe for Photovoltage and Efficiency Enhancement in Exciplex Quantum Dot Sensitized Solar Cells
Shuang, Jiao; Qing, Shen; Mora-Sero, Ivan; Jin, Wang; Zhenxiao, Pan; Ke, Zhao; Xinhua, Zhong; Bisquert, Juan ACS Publications (2015-01-06)Even though previously reported CdTe/CdSe type-II core/shell QD sensitizers possess intrinsic superior optoelectronic properties (such as wide absorption range, fast charge separation, and slow charge recombination) in ... -
Enhancing the Electronic Properties and Stability of High-EfficiencyTin-Lead Mixed Halide Perovskite Solar Cells via DopingEngineering
Sahamir, Shahrir Razey; Kamarudin, Muhammad Akmal; Ripolles, Teresa S.; Baranwal, Ajay Kumar; Kapil, Gaurav; Qing, Shen; Segawa, Hiroshi; Bisquert, Juan; Hayase, Shuzi American Chemical Society (2022-03-31)Overcoming Voc loss to increase the efficiency of perovskite solar cells (PSCs) has been aggressively studied. In this work, we introduce and compare rubidium iodide (RbI) and potassium iodide (KI) alkali metal halides ... -
High performing PbS Quantum Dot Sensitized Solar Cells exceeding 4% efficiency: The role of metal precursor in the electron injection and charge separation
González Pedro, Victoria; Sima, Cornelia; Marzari, Gabriela; Boix, Pablo P; Gimenez, Sixto; Qing, Shen; Dittrich, Thomas; Mora-Sero, Ivan Royal Society of Chemistry (2013)Here we report the preparation of high performance Quantum Dot Sensitized Solar Cells (QDSCs) based on PbS–CdS co-sensitized nanoporous TiO2 electrodes. QDs were directly grown on the TiO2 mesostructure by the Successive ... -
Improvement of Photovoltaic Performance of Colloidal Quantum Dot Solar Cells Using Organic Small Molecule as Hole-Selective Layer
Zhang, Yaohong; Wu, Guohua; Mora-Sero, Ivan; Ding, Chao; Liu, Feng; Huang, Qingxun; Ogomi, Yuhei; Hayase, Shuzi; toyoda, taro; Wang, Ruixiang; Otsuki, Joe; Qing, Shen American Chemical Society (2017-04)A novel organic small molecule bis-triphenylamine with spiro(fluorene-9,9′-xanthene) as the conjugated system, named BTPA-4, is successfully synthesized and employed as the hole-selective layer (HSL) in colloidal quantum ...
