Insights into photovoltaic properties of ternary organic solar cells from phase diagrams

Roland Hany, Jakob Heier, Philippe Schwaller, Surendra Babu Anantharaman

The efficiency of ternary organic solar cells relies on the spontaneous establishment of a nanostructured network of donor and acceptor phases during film formation. A fundamental understanding of phase composition and arrangement and correlations to photo ...

Thermo-mechanical stability of lightweight glass-free photovoltaic modules based on a composite substrate

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Hengyu Li, Laure-Emmanuelle Perret Aebi, Valentin Chapuis, Ana Cristina Oliveira Martins

Lightweight PV modules are attractive for building-integrated photovoltaic (BIPV) applications, especially for renovated buildings, where the additional load bearing capacity is limited. This work focuses on the development of a lightweight, glass-free pho ...
