Perovskite Thin-film Photovoltaic.

Solid-state lead halide perovskites have recently emerged as the latest thin-film photovoltaic (PV) device class. High power conversion efficiencies (> 22 %) and stabilities (> 1000 hours at 80 ˚C under 1 sun illumination) have been obtained using lab scale processes and small area cells (< 1 cm2). The building blocks of the perovskite materials are very low cost and the processing into the final perovskite thin-film can be achieved with fast, low-temperature processes. This makes these materials very cost-efficient, and promises to deliver a future PV technology with a levelled cost of electricity (LCOE) below that of existing mainstream PV. There has been much advancement with combining perovskite with silicon cells, to deliver a “tandem” junction cell with much higher efficiency than either sub-cell. While this perovskite-on-silicon approach is likely to deliver the first perovskite PV products, it restricts the manufacturing and module format to wafer-based architectures, and hence misses out on the real promise of ultimate high-volume manufacturing via large area sheet-to-sheet or reel-to-reel coating.

Within PERTPV we will advance the perovskite thin-film PV technology to the next level by undertaking a “double pronged” drive on both performance (efficiency and stability) and the development of scalable device and module fabrication methodologies, compatible with high-volume manufacturing. Our consortium consists of the leading academic groups in perovskite PV research, in addition to research companies, and 3 commercial partners at appropriately complementary stages in the value chain (technology driver, materials supplier and equipment supplier). In addition to our ambitions target of surpassing 30% power conversion efficiency in a thin film all-perovskite tandem cell, and delivering a certifiably stable module technology, we will also perform full life cycle analysis and ensure a safe means to undertake mass deployment and recycling of the Perovskite PV modules.

FHNW leads the work package on environment, health, safety assessment and end-of-life recycling.
