Efficiency increases for solar cells were achieved primarily due to the use of higher quality multi c-Si wafers, which allowed industry-standard 60-cell multi c-Si based modules to reach 265W, without the requirement to perform significant process step changes at the cell stage. “To move existing silicon-based cell capacity further forward now requires new technologies to be implemented, which has the potential to drive solar manufacturing into the first widespread technology buy cycle seen within the industry,” Colville noted.
According to the latest NPD Solarbuzz PV Equipment Quarterly, the power rating of industry-standard 60-cell multi-crystalline silicon-based modules is forecast to reach 275W within the next 12 months. “The solar PV industry previously operated without a clear technology roadmap, which is no longer an option in the rapidly growing solar PV industry,” said Finlay Colville, vice president of NPD Solarbuzz. “Legacy over-capacity within the industry, combined with uncertainty arising from trade disputes, is now forcing cell manufacturers to improve manufacturing processes to attain record efficiencies.
