Thin-Film Solar Glass for Building-Integrated Photovoltaics
Conventional photovoltaic (PV) panels face key limitations in efficiency, design flexibility, and sustainability. Though widely adopted, crystalline silicon modules are heavy, visually intrusive, and perform poorly under shading or high-temperature conditions. Their installation is typically restricted to rooftops, limiting energy yield in space-constrained urban environments. Moreover, silicon-based PV manufacturing involves energy-intensive processes and carbon emissions that run counter to the goals of green construction.
This thin-film cadmium telluride (CdTe) solar glass technology overcomes the limitations of conventional photovoltaics by integrating photovoltaic elements into glass for building-integrated photovoltaics (BIPV) applications. It effectively addresses high energy consumption and carbon emissions in modern buildings while maintaining architectural aesthetics. Achieving a conversion efficiency of 22.1% under laboratory conditions, the CdTe solar glass delivers outstanding low-light and temperature performance, ensuring reliable energy generation across diverse environments. The design is highly customizable for seamless integration with glass, stone, or aluminum façades—supporting applications such as curtain walls, sunshades, skylights, and other façade elements. By generating clean energy without compromising transparency or design versatility, the technology offers a practical pathway toward energy-efficient, low-carbon urban development, helping stakeholders meet green building and ESG objectives.
The technology owner is seeking collaboration with Singapore-based building material manufacturers, glass processors and architectural firms to jointly advance the integration of sustainable energy technologies into urban infrastructure, supporting Singapore’s transition toward low-carbon, energy-efficient buildings.
