Vertically Aligned 2D/3D Pb-Sn Perovskites with Enhanced Charge Extraction and Suppressed Phase Segregation for Efficient Printable Solar Cells

Mohammad Khaja Nazeeruddin, Tom Theodorus Antonius Lummen, Fei Guo, Xuehui Liu, Chaohui Li, Shi Chen

The concept of mixed 2D/3D heterostructures has emerged as an effective method for improving the stability of lead halide perovskite solar cells, which has been, however, rarely reported in lead-tin (Pb-Sn) mixed perovskite devices. Here, we report a scala ...

Ligand-free nano-grain Cu2SnS3 as a potential cathode alternative for both cobalt and iodine redox electrolyte dye-sensitized solar cells

Mohammad Khaja Nazeeruddin, Xu Pan, Jian Wen, Feng Liu, Shi Chen

Tetragonal phase Cu2SnS3 (CTS) in the form of nano-grain thin film serves as an efficient inexpensive electrocatalyst alternative to the commonly used Pt in dye-sensitized solar cells (DSSCs) exhibiting remarkable electrochemical stability and electrocatal ...
