Establishing the Basis for Industrial Development

The project reported that perovskite solar cells (PSC) were both efficient and stable, confirming the potential viability and cost-competitiveness of PSC technology for commercial-scale manufacture.Validate the commercialisation potential of PSC technology; Confirm the appropriate architecture of PSC’s for efficiency and stability; Establish the viability of PSC technology for scale-up and manufacture.Key resultsCommon belief is that silicon-perovskite tandems are the technologically “easiest” form of perovskite technology to industrialise. This has proven more difficult in practice, as the technical requirements for a silicon-perovskite tandems include all the needs for a perovskite-only device, plus an additional number of challenges. The additional needs make the technology development pathway for silicon-perovskite tandems substantially more demanding than the pathway for perovskite-only devices.A prerequisite for a successful silicon-perovskite tandem device is a viable perovskite-only device. If silicon-perovskite tandem device R&D is to be pursued, then delivering an industrially viable perovskite-only device to ensure that silicon-perovskite devices are worthwhile at all is a priority.For silicon-perovskite tandem products to generate much lower $/Wp cost, the perovskite component has to be both high performing and low cost. It is conceivable that lower $/Wp figures will be obtained from perovskite-only devices or perovskite-perovskite tandems, due to the inherently low cost base of perovskites
