The escalating demand for solar energy highlights the critical need for advancing more efficient next-generation photovoltaic (PV) technologies. Currently, perovskite-based single junction and tandem solar cells are reaching or even exceeding the performance of established technologies like three-five tandem and GaAs solar cells. In the case of perovskite versus GaAs, employing nanophotonics to fine-tune the PV bandgap emerges as a viable strategy, especially when reaching the limits of composition engineering of FAPbI3. Tandem solar cells present another practical approach to surpass the single-junction Shockley-Queisser limit. Our initial efforts concentrated on solution-coating thick perovskite layers onto small, textured silicon substrates, successfully proving the concept's viability. In Singapore, we are actively working to shift this technology from laboratory research to manufacturing, focusing on applying perovskite layers to industrial Czochralski (CZ) silicon wafers. With cooperative efforts, our goal is to propel this technology from lab-scale to full-scale fabrication, aiming to surpass the performance of three-five PVs in full module size, thereby addressing the growing global energy demands with more efficient solar solutions.
