First Solar Inc. is planning a limited production run of the world’s first bifacial solar panel utilizing an advanced thin film semiconductor. The fully functional pre-commercial Series 6 Plus Bifacial photovoltaic (PV) module made its industry debut at Intersolar Europe in Munich, Germany.
The module, which is undergoing field and laboratory testing, builds on the track record of First Solar’s successful Series 6 monofacial module platform. The module features an innovative transparent back contact, pioneered by First Solar’s research and development (R&D) teams. In addition to enabling bifacial energy gain, it allows infrared wavelengths of light to pass through rather than be absorbed as heat. It is expected to lower the operational temperature of the bifacial module and result in a higher specific energy yield.
“This module combines the quality, sustainability, reliability and long-term performance of our Series 6 Plus platform with our first increment of bifaciality,” says Pat Buehler, chief product officer, First Solar. “Once commercialized, we expect Series 6 Plus Bifacial to represent the first real alternative to crystalline silicon-based bifacial technology, effectively combining bifaciality with the industry’s best warranted degradation rate, CdTe thin film’s ability to deliver more energy per nameplate watt, best-in-class reliability and durability and innovative module design.”
