• closedAccess   Impact of Capacitive Effect and Ion Migration on the Hysteretic Behavior of Perovskite Solar Cells 

      Chen, Bo; Yang, Mengjin; Zheng, Xiaojia; Wu, Congcong; Li, Wenle; Yan, Yongke; Bisquert, Juan; Garcia-Belmonte, Germà; Zhu, Kai; Priya, Shashank American Chemical Society (2015-11)
      In the past five years, perovskite solar cells (PSCs) based on organometal halide perovskite have exhibited extraordinary photovoltaic (PV) performance. However, the PV measurements of PSCs have been widely recognized to ...
    • openAccess   Mechanisms of charge accumulation in the dark operation of perovskite solar cells 

      Ripolles, Teresa S.; Baranwal, Ajay K.; Nishinaka, Koji; Ogomi, Yuhei; Garcia-Belmonte, Germà; Hayase, Shuzi Royal Society of Chemistry (2016)
      In this work, a new current peak at forward bias in the dark current–voltage curves has been identified for standard mesoscopic perovskite solar cells. This characteristic peak appears only under some specific conditions, ...
    • openAccess   New iridium complex as additive to the spiro-OMeTAD in perovskite solar cells with enhanced stability 

      Badia Bou, Laura; Mas, Elena; S. Sánchez, Rafael; Barea, Eva M; Bisquert, Juan; Mora-Sero, Ivan AIP Publishing (2014-07-23)
      A new iridium complex, IrCp*Cl(PyPyz)[TFSI], has been synthesized and used as additive for the hole transporter material, spiro-OMeTAD, in perovskite solar cells. The cells prepared with this Ir additive present higher ...
