Considering the rapid advancements in perovskite technology, what specific tandem efficiency and reliability benchmarks must be achieved to ensure competitive LCOE compared to crystalline silicon?
Current data suggests that while perovskite-silicon tandem technologies hold promise, achieving sufficient tandem efficiency and reliability is crucial for market competitiveness. Meeting the degradation values of crystalline silicon is a key target.
Analysis indicates that a tandem efficiency of 26-27% may not be sufficient to compete with crystalline silicon in terms of cost per watt peak and LCOE. Higher efficiencies are necessary to achieve LCOE parity.

Given the dominance of mounting systems and inverters in the overall environmental impact of PV power plants, how can innovations in these areas contribute to a more sustainable deployment of perovskite-based solar technology?
Given the dominance of mounting systems and inverters in the overall environmental impact of PV power plants, how can innovations in these areas contribute to a more sustainable deployment of perovskite-based solar technology?
While perovskite materials themselves contribute relatively little to the overall environmental impact of a PV power plant across most categories, the mounting system, inverter, and silicon cell production are significant contributors. One exception is ionizing radiation, which is elevated due to the high fraction of nuclear energy in France, where the perovskite production is assumed to take place in this analysis.
The mounting system and inverter dominate the environmental impact, followed by the silicon cell. This suggests that focusing on improving the sustainability of these components could significantly reduce the overall environmental footprint of PV power plants, even when using perovskite-based modules.

Considering the established dominance of crystalline silicon in the PV market, what strategic approaches can facilitate the successful market introduction of perovskite technologies for large-scale applications?
Introducing novel materials into the PV market is challenging, especially when competing against the established crystalline silicon industry. The multi-gigawatt scale of crystalline silicon production creates a significant barrier to entry for new technologies like perovskites.
To successfully introduce perovskites, it is crucial to advance rapidly on the learning curve. Even if perovskite technology is inherently less costly than crystalline silicon, the latter's advanced position on the learning curve, due to its high cumulative production, makes it difficult for perovskites to compete on price alone.
