3.1.4 Techno-Economic Analyses

• Progress techno-economic analyses to direct research to commercially relevant outcomes, comparing monolithic tandems and mechanical-stacked tandems. The comparison will be insightful to evaluate the integration-effort-savings in mechanicalstacked tandems and the greater flexibility in cells fabrication and optimization. Cost drivers for each of the perovskite-based tandem technologies will be assessed and identified to inform research.
