Material Development for Perovskite/Silicon Tandem Photovoltaics

Peter Joseph Fiala

The developed world is built on the fact that energy is readily available and functionally infinite. The electricity from the wall, the gas at the station, and the heat in our homes are reliable and low-cost. But this comfort is so far only possible throug ...

Zero-dimensional hybrid iodobismuthate derivatives: from structure study to photovoltaic application

Mohammad Khaja Nazeeruddin, Yi Zhang, Kurt Schenk, Farzaneh Fadaei Tirani, Philip Pattison, Peng Gao

The quest for lead-free light-absorbing perovskite materials has long been the target of researchers to make the 'star' material friendly to the commercial market. After a summary of different lead-free solar absorbers, we demonstrate a zero-dimensional io ...

A comprehensive experimental study of five fundamental phenothiazine geometries increasing the diversity of the phenothiazine dye class for dye-sensitized solar cells

Ulf Anders Hagfeldt

Phenothiazine is a versatile scaffold frequently used in both pharmaceutical and photovoltaic applications. Still, the structural diversity within the class of phenothiazine sensitizers for dye-sensitized solar cells is minute. Substituents are found in 3, ...

Instability of p-i-n perovskite solar cells under reverse bias

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Arnaud Walter, Daniel Anthony Jacobs, Ricardo Augusto Zanotto Razera, Sylvain Nicolay, Laura Ding, Fan Fu, Chien-Jen Yang, Peter Joseph Fiala, Marion Solange Madeleine Dussouillez

Partial shading can trigger permanent damage in photovoltaic modules because the illuminated solar cells drive the shaded cells into reverse bias. Under reverse bias conditions, perovskite solar cells have been shown to degrade quickly due to processes tha ...
