Stable and efficient architectures for perovskite solar modules and tandems

The efficiency of perovskite solar cells (PSCs) has seen an unprecedented increase in few years’ times, with nowadays certified values exceeding 25%. Also in tandem architectures, record values well above 30% have been reported recently. Obviously, this has created a lot of enthusiasm not only in the research community but overall, in the photovoltaic (PV) industry.
Scepticism remains though, as cost-effective scale-up, sustainability and long-term reliability need to be proven still. This requires an appropriate assessment of materials, device configurations as well as processes to filter out those ones that can result in effectively raising the technology readiness level (TRL) of this high-potential emerging PV technology.

Both for single junction modules as for tandems, with these considerations in mind, we have systematically put together processes and architectures bringing this technology closer to industrialization. Results will be presented on how we came to these selections and how this approach enabled taking substantial steps forward.
