Are tandem photovoltaic (PV) modules cost-effective?

Tandem photovoltaic (PV) modules offer an opportunity to improve the efficiency and energy yield of available solar resources compared with single-junction devices. We present a cost model and sensitivity analysis of perovskite/silicon (Si) tandem modules to understand how design choices impact overall module costs.

Are tandem solar modules a good option?

Tandem PVs offer an opportunity to improve module efficiencies compared with single-junction technologies today. The continuous reduction in costs for single-junction technologies makes entering the solar module market more difficult for tandem modules on a basis of cost.

How can tandem modules be introduced to the PV market?

Two predominant pathways discussed for introducing tandem modules to the PV market are through new markets (i.e., transportation and the built environment) and rapid scale-up within the global module market.

Are perovskite-based Tandem solar modules economically competitive?

Although intensive investigations are being made on their technical feasibility, serious analysis on the cost of perovskite-based tandem modules is lacking. The levelized cost of electricity (LCOE) of solar modules is often used to evaluate technoeconomic competitiveness.

Why should we commercialize tandem modules?

Commercializing tandem modules offers an opportunity to expedite the transition to renewable and sustainable energy sources and improve the value of the energy generating technologies we deploy.

Can tandem solar cells convert sunlight into electricity?

Traditional silicon-based solar cells are in use worldwide. However, further advancements are already in the pipeline. Now, tandem solar cell technologies – specifically, stacking an ultrathin perovskite solar cell on top of a standard silicon solar cell – are breaking records in converting sunlight into electricity.
