Corporate Laboratory Group

This group hosts, manages and operates the REC@NUS Corporate R&D Laboratory for Next Generation Photovoltaics established at SERIS in 2023. The group focuses on the development and commercialisation of two-terminal (2T) perovskite-silicon tandem solar cell and module technologies. The key research areas are (1) high-throughput and ultra-fast deposition methods to enable > 30% efficiency for industrially relevant large-area (≥ 244 cm²) 2T tandem solar cells with high long-term device stability, (2) tackling process and equipment upscaling challenges to reduce the barriers to manufacturing for perovskite-silicon tandem solar cells, and (3) establishing rapid metrology and monitoring techniques suitable for production line environments to enable reliable process control methods for 2T tandem solar cell manufacturing. The heart of the Corporate Laboratory project is a dedicated 200‑m² zone that will house state-of-the-art ultra-fast deposition machines for the fabrication of large-area perovskite solar cells on silicon substrates with sizes up to G12 (210 mm ´ 210 mm). The SERIS project staff also utilize SERIS’ Silicon cleanroom lab where heterojunction bottom cells are made using large-area industrial Cz silicon substrates. The SERIS group works in close partnership with local solar cell & module manufacturer REC Solar, and collaborates with external research teams (e.g. at Nanyang Technological University, NTU) as well as several equipment, automation and materials companies to establish a leading ecosystem for tandem photovoltaics in the region.
