In situ dynamic observations of perovskite crystallisation and microstructure evolution intermediated from [PbI6](4-) cage nanoparticles

Michael Graetzel, Wei Zhang, Lichen Zhao, Feng Liu, Cheng Wang, Rui Zhu, Ke Gao

Hybrid lead halide perovskites have emerged as high-performance photovoltaic materials with their extraordinary optoelectronic properties. In particular, the remarkable device efficiency is strongly influenced by the perovskite crystallinity and the film m ...

Enabling full-scale grain boundary mitigation in polycrystalline perovskite solids

Michael Graetzel, Shaik Mohammed Zakeeruddin, Felix Thomas Eickemeyer, Ulf Anders Hagfeldt, Jingshan Luo, Yuhang Liu, Lichen Zhao

There exists a considerable density of interaggregate grain boundaries (GBs) and intra-aggregate GBs in polycrystalline perovskites. Mitigation of intra- aggregate GBs is equally notable to that of interaggregate GBs as intra-aggregate GBs can also cause d ...

Toward an alternative approach for the preparation of low-temperature titanium dioxide blocking underlayers for perovskite solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Kazuteru Nonomura, Lichen Zhao, Su Htike Aung

The anodic electrodeposition method is investigated as an alternative technique for the preparation of a titanium oxide (TiO2) blocking underlayer (UL) for perovskite solar cells (PSCs). Extremely thin Ti-IV-based films are grown from aqueous acidic titani ...
