Bandgap Engineering Demonstrates Record Performance for Low-Cost Nanotextured Silicon Solar Cells
Bandgap Engineering, Inc. announced today that its proprietary and patented nanotextured silicon solar cells demonstrated a 0.3% absolute efficiency boost over industry-standard solar cells. The Bandgap nanotextured, 156 mm multicrystalline silicon cells, made in collaboration with Georgia Institute of Technology, achieved average efficiencies of 16.7%, as compared to industry-standard control cells that averaged 16.4%. Importantly, all the cells were processed using conventional processes including a standard emitter, silicon-nitride, screen-printed metallization with an aluminum back surface field.
“This efficiency boost is particularly impressive given that we have just begun to tune the cell process for our nanotextured silicon solar-cells,” stated Marcie Black, CTO of Bandgap. “When fully optimized we expect our cells will have an efficiency approximately 1% absolute higher than standard multicrystalline cells.”
“These results validate our strategy to upgrade existing crystalline silicon production lines with a low-cost, drop-in improvement,” commented Richard Chleboski, CEO of Bandgap. “We are ready to work with manufacturers interested in upgrading their production lines to sell a premium, differentiated products at lower costs per watt. In short, when fully implemented, our partners will be able to obtain monocrystalline cell performance and pricing with multicrystalline wafers and costs.”
