• openAccess   Cooperative kinetics of depolarization in CH3NH3PbI3 perovskite solar cells 

      Bertoluzzi, Luca; S. Sánchez, Rafael; Liu, Linfeng; Lee, Jin Wook; Mas, Elena; Han, Hongwei; Park, Nam-Gyu; Mora-Sero, Ivan; Bisquert, Juan Royal Society of Chemistry (2015)
      Despite the large photovoltaic performance recently achieved, many aspects of the working principles of hybrid organic–inorganic perovskite solar cells remain to be unveiled. We analyze the experimental features observed ...
    • 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   Recombination reduction on lead halide perovskite solar cells based on low temperature synthesized hierarchical TiO2 nanorods 

      Jaramillo Quintero, Óscar A.; Solís de la Fuente, Mauricio; S. Sánchez, Rafael; Recalde, Ileana B.; Juarez-Perez, Emilio J.; Rincón, Marina; Mora-Sero, Ivan Royal Society of Chemistry (2016)
      Intensive research on the electron transport material (ETM) has been pursued to improve the efficiency of perovskite solar cells (PSCs) and decrease their cost. More importantly, the role of the ETM layer is not yet fully ...
    • openAccess   Tunable Open Circuit Voltage by Engineering Inorganic Cesium Lead Bromide/Iodide Perovskite Solar Cells 

      Ng, Chi Huey; Ripolles, Teresa S.; Hamada, Kengo; Teo, Siow Hwa; Lim, Hong Ngee; Bisquert, Juan; Hayase, Shuzi Nature Publishing Group (2018)
      Perovskite solar cells based on series of inorganic cesium lead bromide and iodide mixture, CsPbBr3-xI x , where x varies between 0, 0.1, 0.2, and 0.3 molar ratio were synthesized by two step-sequential deposition at ambient ...
