Project: HIgh-Efficiency Si PERovskite Tandem Solar Cells eXtra Large
| Acronym | HIPER XL (Reference Number: 68) |
| Duration | 01/04/2021 - 31/03/2023 |
| Project Topic | The IEA has reported in its “Renewables 2019” report that a solar PV capacity growth of 700-880 GW is expected until 2024. Current Si PV technology has a mainstream efficiency of ~22%, which would increase up to an economically feasible efficiency of 24-25%. A proven method to improve the power output is to create tandem devices. In this context, perovskite/c-Si tandem technology can make an impact: the high-power output, results in a lower footprint for PV systems, and offers a route to lower the levelized cost of electricity. Within HIPER XL, the consortium will demonstrate environmentally benign, stable, efficient and cost effective, four terminal (4T) bifacial hybrid tandem solar cells with unprecedented power output, manufactured with scalable process routes. The concept of bifacial perovskite/c-Si tandem modules was published for the first time by HIPER XL consortium members in April 2020. Our preliminary investigations resulted in a device with a power output of 30.5 mW/cm2 for lab-scale cells under BiFi200 conditions. By building on our joint background the consortium will deliver in 24 months, four terminal bifacial hybrid tandem cells with a power output of 32 mW/cm2 on 3x3 cm2 area substrates, an analogous 6x6 inch2 device delivering 28 mW/cm2 under BiFi200 conditions and a demonstrator on 35 x 35 cm2. We aim to pass damp-heat light soaking tests for 3000 hours, and thermal cycle between -40 ºC to 85 ºC for 200 cycles, with at least 90% of the initial power output. The stability and annual yield of these modules will be investigated in outdoor tests in two different climate zones (Turkey and The Netherlands). HIPER XL conducts an ecological footprint study (with a focus on the perovskite elements) and a cost assessment survey to evaluate the potential to further reduce the levelized cost of solar electricity. |
