Solar-Driven Perovskite Tandem for Methanol Production

The SUNPEROM project aims to transform renewable energy by developing a solar-driven system for direct methanol synthesis from atmospheric CO2. The primary objective is to achieve a Solar-to-Methanol efficiency exceeding 12% through the creation of an innovative, cost-effective tandem device. This device features a high-voltage perovskite-perovskite solar conversion stack and an advanced near-infrared (NIR) photocatalyst-mixed gas diffusion layer for efficient CO2 capture and conversion, utilizing the full solar spectrum.Taking a high-risk, high-reward approach, SUNPEROM targets significant breakthroughs in solar fuel production technology, delivering green methanol at a competitive price. The technology integrates diverse renewable energy components, including high-voltage all-perovskite tandem solar cells, NIR photocatalysts, solid-state CO2 capture, and direct electroreduction of CO2, representing a comprehensive approach to solar fuel production.The project emphasizes advancing cutting-edge technologies and contributing to a net-zero greenhouse gas emissions economy. To elevate the Technology Readiness Level (TRL), the project includes plans for standardized validation of the SUNPEROM tandem device, with a clear focus on moving beyond the conceptual stage towards practical implementation. Environmental and social impacts are also prioritized, with a thorough Life Cycle Analysis (LCA) planned to assess sustainability.Additionally, the proposal benchmarks SUNPEROM against current commercial technologies, aiming to surpass existing performance standards, reduce production costs, minimize land use, and achieve a low energy payback time for sustainable solar fuel production. Regulatory compliance is a key aspect, ensuring alignment with current policies for a smooth transition to commercialization.
