Composition engineering of Cu2ZnGexSn1-xS4 nanoparticles hole transport layer for carbon electrode-based perovskite solar cells Cu2ZnSnS4 (CZTS) and Cu2ZnGeS4 (CZGS) nanoparticles are important inorganic hole transport layers (HTLs) for carbon electrode-based perovskite solar cells (C-PSCs), however the performances of the corresponding C-PSCs are still not satisfactory, which mainly originates from the un-optimized photo-electronic properties of the pristine CZTS and CZGS nanoparticles....

Two-step deposition method has been widely exploited to fabricate FA1-xCsxPbI3 perovskite solar cells. However, in previous studies, CsI is mainly added into the PbI2 precursor with DMF/DMSO as solvent. Here in this study, a novel method to fabricate FA1-xCsxPbI3 perovskite has been proposed. The CsI is simultaneously added into the PbI2 precursor and the organic FAI/MACl salts solution in our modified two-step deposition process.
