      Almora Rodríguez, Osbel; Taek Cho, Kyung; Aghazada, Sadig; Zimmermann, Iwan; Matt, Gebhard J.; Brabec, Christoph J.; Nazeeruddin, Mohammad Khaja; Garcia-Belmonte, Germà Elsevier (2018)
      The ubiquitous hysteresis in the current-voltage characteristic of perovskite solar cells (PSCs) interferes in a proper determination of the diode ideality factor (n), a key parameter commonly adopted to analyze recombination ...
    • openAccess   Selective Growth of Layered Perovskites for Stable and Efficient Photovoltaics 

      Taek Cho, Kyung; Lee, Yonghui; Almora Rodríguez, Osbel; Grancini, Giulia; Ryu, Jaehoon; Tschumi, Manuel; Jang, Jyongsik; Paek, Sanghyun; Garcia-Belmonte, Germà; Nazeeruddin, Mohammad Khaja Royal Society of Chemistry (2018-11)
      Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under operation ...
