Enhanced efficiency and stability in Sn-based perovskite solar cells by trimethylsilyl halide surface passivation
Zhang, Zheng; Wang, Liang; Kumar Baranwal, Ajay; Sahamir, Shahrir Razey; Kapil, Gaurav; Sanehira, Yoshitaka; Kamarudin, Muhammad Akmal; Nishimura, Kohei; Ding, Chao; Liu, Dong; Li, Yusheng; Li, Hua; Chen, Mengmeng; Shen, Qing; Ripolles, Teresa S.; Bisquert, Juan; Hayase, Shuzi Elsevier (2022-05-13)Lead free tin perovskite solar cells (PKSCs) are the most suitable alternative candidate for conventional lead perovskite solar cells. However, the efficiency and the stability are insufficient, mainly because of the poor ... -
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 ... -
High-Efficiency Lead-Free Wide Band Gap Perovskite Solar Cells via Guanidinium Bromide Incorporation
Chen, Mengmeng; Kamarudin, Muhammad Akmal; Baranwal, Ajay Kumar; Kapil, Gaurav; Ripolles, Teresa S.; Nishimura, Kohei; Hirotani, Daisuke; Sahamir, Shahrir Razey; Zhang, Zheng; Ding, Chao; Sanehira, Yoshitaka; Bisquert, Juan; Shen, Qing; Hayase, Shuzi American Chemical Society (2021-09-27)Despite lead halide perovskite(top)/silicon(bottom) tandem solar cell achieving >29% efficiency, the toxicity of lead limits the adoption of perovskites in electronic devices. To solve this problem, tin perovskite has been ... -
Large Grain Growth and Energy Alignment Optimization by Diethylammonium Iodide Substitution at A Site in Lead-Free Tin Halide Perovskite Solar Cells
zhang, zheng; Baranwal, Ajay Kumar; Sahamir, Shahrir Razey; Kapil, Gaurav; Sanehira, Yoshitaka; Chen, Mengmeng; Nishimura, Kohei; Ding, Chao; Liu, Dong; Li, Hua; Li, Yusheng; Kamarudin, Muhammad Akmal; Shen, Qing; Ripolles, Teresa S.; Bisquert, Juan; Hayase, Shuzi Wiley (2021-10-13)Environment-friendly tin perovskite solar cells (T-PKSCs) are the most suitable alternative candidate for lead-free PKSCs. However, the photovoltaic performance of such T-PKSCs is far below those of lead-based perovskite ...
