Perovskite solar modules have shown considerable developments in the last decade, and commercial applications are drawing closer. Here, we propose a new techno-economic study of this technology and place these results in the PV market sector at large. We find that the cost for manufacturing perovskite modules could still vary from 10 to almost 100 €/m2 [1,2], and that the perovskite module cost is strongly dependent on the manufacturing throughput of the plant. This manufacturing cost can be decomposed into CAPEX, OPEX and materials costs, where the main contribution comes from the materials costs, specifically the front substrate, the encapsulation scheme, and the junction box [2,3,4]. We further calculate the LCOE as a function of module efficiency and stability. The corresponding 2D maps are shown for four different module cost scenarios, at 12.5, 25, 50, and 100 €/m2. We find that all of these parameters, namely module cost, efficiency, and stability, matter towards the final LCOE value, and that the resulting LCOE varies from 4 to 23 cents €/kWh. There is a potential for competition with silicon, but the conditions remain restrictive. Finally, we modify the LCOE equation to highlight the benefit of producing low-weight modules by roll-to-toll deposition. This leads to a reduced LCOE, making the comparative advantage toward silicon PV stronger. Together, these results suggest a strong incentive for the production of light-weight perovskite modules.
