Enhancing the Electronic Properties and Stability of High-EfficiencyTin-Lead Mixed Halide Perovskite Solar Cells via DopingEngineering
Sahamir, Shahrir Razey; Kamarudin, Muhammad Akmal; Ripolles, Teresa S.; Baranwal, Ajay Kumar; Kapil, Gaurav; Qing, Shen; Segawa, Hiroshi; Bisquert, Juan; Hayase, Shuzi American Chemical Society (2022-03-31)Overcoming Voc loss to increase the efficiency of perovskite solar cells (PSCs) has been aggressively studied. In this work, we introduce and compare rubidium iodide (RbI) and potassium iodide (KI) alkali metal halides ... -
Impedance spectroscopic analysis of high-performance dye sensitized solar cells based on nano-clay electrolytes
González Pedro, Victoria; Sakurai, Hideki; Tomita, Mitsuru; Ito, Bruno Ieri; Fabregat-Santiago, Francisco; Uchida, Satoshi; Segawa, Hiroshi Elsevier (2016)In this work we present quasi-solid state dye-sensitized solar cells obtained employing artificial hydrotalcite nano-clay as electrolyte additive, with a greatly improved photo-energy conversion efficiency of up to 10.9% ... -
Temperature Effects on the Photovoltaic Performance of Planar Structure Perovskite Solar Cells
Cojocaru, Ludmila; Uchida, Satoshi; Sanehira, Yoshitaka; González Pedro, Victoria; Bisquert, Juan; Nakazaki, Jotaro; Kubo, Takaya; Segawa, Hiroshi Chemical Society of Japan (2015-09-10)Temperature effects of CH3NH3PbI3 perovskite solar cells having simple planar architecture were investigated on the crystal structure and photovoltaic performance. The obvious changes in the CH3NH3PbI3 crystal structure ...
