The effect of illumination on the formation of metal halide perovskite films

Michael Graetzel, Wolfgang Richard Tress, Antonio Abate, Jiyoun Seo, Amita Ummadisingu, Ludmilla Steier, Taisuke Matsui

Optimizing the morphology of metal halide perovskite films is an important way to improve the performance of solar cells(1) when these materials are used as light harvesters(2), because film homogeneity is correlated with photovoltaic performance(3). Many ...

Migration of cations induces reversible performance losses over day/night cycling in perovskite solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ulf Anders Hagfeldt, Wolfgang Richard Tress, Michael Saliba, Antonio Abate, Filippo de Angelis, Konrad Domanski, Juan-Pablo Correa-Baena, Silver Hamill Turren Cruz

Perovskites have been demonstrated in solar cells with a power conversion efficiency of well above 20%, which makes them one of the strongest contenders for next generation photovoltaics. While there are no concerns about their efficiency, very little is ...

Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance

Michael Graetzel, Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Jiyoun Seo, Amita Ummadisingu

All of the cations currently used in perovskite solar cells abide by the tolerance factor for incorporation into the lattice. We show that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a "cation cascade" to create perovskite mat ...

Highly efficient and stable planar perovskite solar cells by solution-processed tin oxide

Michael Graetzel, Ulf Anders Hagfeldt, Wolfgang Richard Tress, Michael Saliba, Antonio Abate, Konrad Domanski, Juan-Pablo Correa-Baena, Ludmilla Steier, Taisuke Matsui, Elham Halvani Anaraki

Perovskite solar cells (PSCs) are one of the most promising lab-scale technologies to deliver inexpensive solar electricity. Low-temperature planar PSCs are particularly suited for large-scale manufacturing. Here, we propose a simple, solution-processed te ...
