Once again, Oxford PV has announced a new efficiency record for a perovskite-silicon solar tandem – outperforming HZB's previous mark (29.15% efficiency). In line with these achievements, both organizations are aiming to push the performance of perovskite-silicon tandems beyond 30% in the near future. Despite commercialization delays related to the ongoing COVID-19 pandemic, Oxford PV is in the process of ramping up the production of perovskite-silicon cells and is targeting commercialization in mid-2021. Clients should expect perovskite cells to gain significant traction this year; once commercialized, the most crucial factor that will define product economics will be module-level performance and durability in outdoor environments.
