Thin Film Technology for Flexible Solar
Photovoltaics
Thin film solar cell technologies offer new solutions for integrating solar electricity generation into the modern economy . These not only enable flexible photovoltaic products , but also lower the cost of silicon PV by increasing solar photovoltaic energy conversion efficiency through the use of high-efficiency tandem cells . |
Competitive Advantage • Hold the world record of 11.4 % for highest efficiency high bandgap pure sulphide Kesterite CZTS ( Cu2ZnSnS4 ) solar cells , and have established five world records for this photovoltaic technology
• Developed 24.8 % efficient low-temperature (< 200 ° C ) processed planar perovskite solar cells with significantly improved stability without encapsulation
• Developed above 30 % efficiency III-V / Si tandem solar cells
• Developed 9.6 % efficiency all-inorganic emerging antimony chalcogenide solar cells
• Designing and developing new PV materials made from environmentally-friendly and earth-abundant materials for Silicon-based tandem cells
Impact • The goal is to make solar photovoltaic more efficient , cost-effective and competitive for the energy market and for their applications in various aspects of our lives , such as building and vehicleintegrated PV and portable power sources
• Kesterite breakthroughs represent a major advancement in the development of flexible , stable , cheap and non-toxic solar cells
|
