The cost of ownership (CoO) of perovskite PV technology was calculated for the production of both perovskite-Si tandem and single junction perovskite cell modules. The relevant cost data for manufacturing such modules was estimated by Oxford PV Ltd. using their pilot production line process located in Germany and utilised in the cost calculations for 1GWp annual module production.

A price of €0.25 per Watt peak for 380W perovskite-Si tandem cell modules and 0.20 €/Wp for 280W perovskite single junction cell modules were calculated for a 1GWp mass production plant. The CoO of the 1GWp module line for both module types is already at a competitive level with the present and future equivalent c-Si only module production of 0.31 €/Wp in 2018 and 0.25 €/Wp in 2020. The price advantage of the tandem cell modules improves further when the total system price is considered and the much higher efficiency of the tandem modules is taken into account.

Our calculations also confirm the commercial potential for perovskite only single junction modules, our calculated cost of 0.20 €/Wp is competitive with the predicted future c-Si module price.
