The 24-7%-efficient module uses a simplified 54 half-cell shingled back-contact design with full rear-side electrical connections, which the company says improves efficiency, reliability, and mechanical robustness.
China-based solar module maker TCL Sunpower has launched today a new back contact (BC) solar module for residential applications at the Smarter E trade show in Munich, Germany.
“A key advantage is the very low temperature coefficient of 0.26%, which helps maintain performance in hot conditions,” the company’s Director of Product Management, Karin Alberto-Burkhardt, told pv magazine. “We also improved the spectral response, allowing earlier morning and later evening energy production. Overall, this can deliver up to 9% higher energy yield, especially in partially shaded or low-light conditions.
“The module uses an optimized shingle back-contact design,” she went on to say. “The manufacturing process has been simplified, removing earlier busbar structures and enabling slight overlap between cells. This improves packing density and contributes to higher efficiency. The module is based on a 54 half-cell format in a shingled layout. Moreover the back-contact architecture ensures full-cell electrical connection on the rear side, improving reliability and reducing front-side shading losses. This is supported by a large patent portfolio in back-contact and tunnel-junction technologies.”
