Perovskite/silicon tandem photovoltaics: Technological disruption without business disruption

Abstract: Meeting the ambitious challenge of net-zero greenhouse gas emissions by 2050 and holding the average increase in global temperature below 1.5 °C necessitate the upscaling of readily available renewable energy sources, especially solar photovoltaics. Since the window of time to achieve this goal is closing fast, it is of paramount importance that we accelerate the decarbonization of the global energy system by increasing the power output of solar cells through advancing their power conversion efficiencies towar… Show more

“…With different combinations of A, B, and X ions, the bandgap can be varied from 1.24 to 3.55 eV . The wide range of bandgap tunability, coupled with versatile preparation procedures, enables new solutions to existing challenges such as deep blue light emitting diodes (LEDs) , and multijunction photovoltaics (PVs). While the multijunction perovskite-Si tandem cells have recently reached a power conversion efficiency (PCE) of 29.5%, exceeding the theoretical limit of the single silicon cell, challenges remain in terms of device stability. The ideal bandgap of the top absorber in a tandem cell is about 1.7 eV, which can be easily achieved by the halide mixing method.…”

“…21 Raw material needs for PERC, SHJ, CIGS and III-V/Si modules were investigated thoroughly, and supply risks based on a material demand-to-production comparison have been identified. 22 Kamaraki et al 23 calculated the time it would take to produce the required materials to create 1-30 TW of PV from selected state-of-the-art cell architectures at the current rate of global primary production. Sustainable manufacturing capacity (SMC) of commercial silicon cell technologies imposed by silver, indium and bismuth was evaluated by Zhang et al 24 In this report, we provide the first thorough analysis of the sustainability issues regarding material consumption for silicon-based tandem solar cells.…”
