• openAccess   Origin of efficiency enhancement in Nb2O5 coated titanium dioxide nanorod based dye sensitized solar cells 

      Barea, Eva M; XU, XUEQING; González Pedro, Victoria; Ripollés Sanchis, Teresa; Fabregat-Santiago, Francisco; Bisquert, Juan Royal Society of Chemistry (2011-05-13)
      Ordered one-dimensional metal oxides are considered promising architectures for dye-sensitized solar cells (DSC). Here we explore the properties determining the photovoltaic performance of DSC based on titanium dioxide ...
    • openAccess   Tunable hysteresis effect for perovskite solar cells 

      Rong, Yaoguang; Hu, Yue; Ravishankar, Sandheep; huawei, liu; Hou, Xiaomeng; Sheng, Yusong; Mei, Anyi; Xu, Mi; Bisquert, Juan; Han, Hongwei Royal Society of Chemistry (2017-09-14)
      Perovskite solar cells (PSCs) usually suffer from a hysteresis effect in current–voltage measurements, which leads to an inaccurate estimation of the device e fficiency. Although ion migration, charge trapping/ detrapping, ...
