The evolution of triphenylamine hole transport materials for efficient perovskite solar cells

Mohammad Khaja Nazeeruddin

In recent years, the dramatic increase in power conversion efficiency (PCE) coupled with a decrease in the total cost of third-generation solar cells has led to a significant increase in the collaborative research efforts of academic and industrial researc ...

New metric for carrier selective contacts for silicon heterojunction solar cells

Mathieu Gérard Boccard, Jakub Holovsky

Heterojunction carrier selective contacts for solar cells have gained great attention because of the ability of these contacts to efficiently collect majority carriers while hindering the recombination of minority carriers, thus resulting in the highest re ...

Implementation and understanding of p plus fired rear hole selective tunnel oxide passivating contacts enabling > 22% conversion efficiency in p-type c-Si solar cells

Christophe Ballif, Franz-Josef Haug, Andrea Ingenito, Matthieu Despeisse, Sylvain Nicolay, Philippe Wyss, Sofia Libraro

Passivating contacts are key enablers for high efficiency c-Si solar cells. Here, we present our latest advancement in terms of implementation and understanding in fired passivating contacts (FPC) used as rear p + passivating contact in p-type solar cells. ...

Pushing the limit of Cs incorporation into FAPbBr3 perovskite to enhance solar cells performances

Mohammad Khaja Nazeeruddin, Berend Smit, Giulia Grancini, Valentin Ianis Emmanuel Queloz, Albertus Adrian Sutanto, Inés Garcia Benito, Olga Syzgantseva

Cation compositional engineering has revealed a powerful design tool to manipulate the perovskite structural and optoelectronic characteristics with a tremendous impact on device performances. Tuning the bandgap by cation and anion compositional mixing, fo ...
