DIAMOND - Ultra-stable, highly efficient, low-cost perovskite photovoltaics with minimized environmental impact

The DIAMOND project joins 6 European leading universities (University of Groningen, Uppsala University, EPFL, University Rome-Tor Vergata, University of Porto, University of Marburg), 2 research institutes (Fraunhofer ISE, CEA) and 4 industry partners (Dyenamo, BeDimensional, Solaronix, PixelVoltaic) from 7 different countries.

We aim at developing ultra-stable, highly-efficient and low-cost perovskite photovoltaics with minimized environmental impact, promising stabilities far beyond all previous achievements of photovoltaic solar cells.

We develop novel hermetic encapsulation approaches and highly stable device designs that are evaluated by standardized and novel stability assessment methods. DIAMOND also aims to optimize materials and cell stacks to reach efficiencies exceeding the record values of silicon PV. Fully printable module architectures are targeted for rapid industrial up-scaling, allowing lower manufacturing costs and local production in the EU. Specific device designs that enable the lowest carbon-footprint, material criticality and toxicity together with enhanced recyclability are targeted.

In Uppsala, we focus on record-high perovskite solar cells by developing cutting edge α-FAPbI3 phase-stabilized perovskite, multifunctional molecularly engineered additives and low dimensional passivation layers as well as optimized stack designs and electrode materials. Furthermore, implementation of ultra-stable and fully printable carbon-based PSC (C-PSC), overcoming instabilities such as interconnection or shading induced degradation. Boost PCE of C-PSC devices to 23%.
