Amorphous TiO2 Buffer Layer Boosts Efficiency of Quantum Dot Sensitized Solar Cells to over 9%
Ren, Zhenwei; Wang, Jin; Pan, Zhenxiao; Zhao, Ke; Zhang, Hua; Li, Yan; Zhao, Yixin; Mora-Sero, Ivan; Bisquert, Juan; Zhong, Xinhua American Chemical Society (2015)Charge recombination at an electrode/electrolyte interface is the main factor to limit the power conversion efficiency (PCE) of quantum dot sensitized solar cells (QDSCs). Herein, we present a novel and facile strategy ... -
Boosting Power Conversion Efficiencies of Quantum-Dot-Sensitized Solar Cells Beyond 8% by Recombination Control
Zhao, Ke; Pan, Zhenxiao; Mora-Sero, Ivan; Cánovas, Enrique; Wang, Hai; Song, Ya; Gong, Xueqing; Wang, Jin; Bonn, Mischa; Bisquert, Juan; Zhong, Xinhua American Chemical Society (2015)At present, quantum-dot-sensitized solar cells (QDSCs) still exhibit moderate power conversion efficiency (with record efficiency of 6–7%), limited primarily by charge recombination. Therefore, suppressing recombination ... -
Core/Shell Colloidal Quantum Dot Exciplex States for the Development of Highly Efficient Quantum-Dot-Sensitized Solar Cells
Wang, Jin; Mora-Sero, Ivan; Pan, Zhenxiao; Zhao, Ke; Zhang, Hua; Feng, Yaoyu; Yang, Guang; Zhong, Xinhua; Bisquert, Juan American Chemical Society (2013)Searching suitable panchromatic QD sensitizers for expanding the light-harvesting range, accelerating charge separation, and retarding charge recombination is an effective way to improve power conversion efficiency (PCE) ... -
High-Efficiency “Green” Quantum Dot Solar Cells
Pan, Zhenxiao; Mora-Sero, Ivan; Shen, Qing; Zhang, Hua; Li, Yan; Zhao, Ke; Wang, Jin; Zhong, Xinhua; Bisquert, Juan American Chemical Society (2014)Semiconductor quantum dots (QDs) are extremely interesting materials for the development of photovoltaic devices, but currently the present the drawback is that the most efficient devices have been prepared with toxic heavy ...
