    • closedAccess   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 ...

    • closedAccess   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 ...

    • closedAccess   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) ...

    • closedAccess   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 ...

    • openAccess   Quantum dot-sensitized solar cells 

      Pan, Zhenxiao; Rao, Huashang; Mora-Sero, Ivan; Bisquert, Juan; Zhong, Xinhua Royal Society of Chemistry (2018)
      Quantum dot-sensitized solar cells (QDSCs) have emerged as a promising candidate for next-generation solar cells due to the distinct optoelectronic features of quantum dot (QD) light-harvesting materials, such as high ...
