The Netherlands Organization for Applied Scientific Research (TNO) and Solarge, a manufacturer of lightweight silicon PV modules based in the Netherlands, have developed a lightweight perovskite solar module prototype measuring 32 cm x 34 cm by combining roll-to-roll processing and low-weight panel materials.
The partners aim to scale the technology for broader commercial applications. It features two novelties: the perovskite absorber was made using a TNO roll-to-roll cell manufacturing process and the cover is glass-free, made of polymer instead of conventional glass. The top sheet is based on the same novel polymer that Solarge uses in its current line of lightweight silicon PV modules that weigh just 5.5 kgs/m2. The back is an organosandwich plate, which is a thermoplastic fiber composite component.
Solarge and TNO aim to develop perovskite solar technology into a mature product to be able to bring it to market, hopefully with some support from initiatives such as the Netherlands Growth Fund.
Details about device performance were not provided, as the partners did not seem to focus on module efficiency for this prototype, but rather demonstrate it is possible to combine their technologies into one module.
The perovskite solar PV technology in development is envisioned for use in flexible, lightweight panels. It could also be used in rigid designs compatible with standard mounting systems.
