High-Stable Lead-Free Solar Cells Achieved by Surface Reconstruction of Quasi-2D Tin-Based Perovskites

Michael Saliba, Guixiang Li, Antonio Abate, Feng Yang, Meng Li, Xingyu Gao, Rui Zhu, Zhe Li

Tin halide perovskites are an appealing alternative to lead perovskites. However, owing to the lower redox potential of Sn(II)/Sn(IV), particularly under the presence of oxygen and water, the accumulation of Sn(IV) at the surface layer will negatively impa ...

Molecular Electronic Study of Spiro-[cyclopenta[1,2-b:5,4-b ']dithiophene-4,9 '-fluorene] Derivatives: Route to Decent Hole-Transporting Materials

Mohammad Khaja Nazeeruddin, Peng Gao, Michael Saliba, Wei Li

Spiro-type molecules have been extensively explored as hole-transporting materials (HTMs) in perovskite solar cells (PSCs). However, a closer look at the rule of design of such molecules is missing, and a combined experimental and theoretical study is need ...

Accounting for Optical Generation in the Quasi-Neutral Regions of Perovskite Solar Cells

Jean-Michel Sallese, Farzan Jazaeri, Parnian Ferdowsi, Michael Saliba

Predicting the performance of solar cells though analytical models is important for the theory-guided optimization of these devices. Earlier models neglect the impact of the optical generation in the quasi-neutral regions of a perovskite solar cell. Here, ...

Synergistic Crystal and Interface Engineering for Efficient and Stable Perovskite Photovoltaics

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Michael Saliba, Pankaj Kumar Yadav, Mohammad Mahdi Tavakoli, Philippe Jürgen Holzhey

The presence of bulk and surface defects in perovskite light harvesting materials limits the overall efficiency of perovskite solar cells (PSCs). The formation of such defects is suppressed by adding methylammonium chloride (MACl) as a crystallization aid ...

Crystal Orientation and Grain Size: Do They Determine Optoelectronic Properties of MAPbI(3) Perovskite?

Sandy Sanchez Alonso, Ulf Anders Hagfeldt, Michael Saliba

Growing large, oriented grains of perovskite often leads to efficient devices, but it is unclear if properties of the grains are responsible for the efficiency. Domains observed in SEM are commonly misidentified with crystallographic grains, but SEM images ...
