Korean solar module producer Hanwha Q Cells has raised the bar for multicrystalline module efficiencies, confirming this week that a standard 300-watt prototype has delivered 19.5% conversion efficiency. The world-record is based on a prototype module made with high-efficiency multicrystalline Q.AMTUM solar cells with four busbars, and was produced at the firm's Center for Technology Innovation and Quality in Thalheim, Germany. Despite being a prototype module at this stage, the pilot line replicated the exact production processes required to mass-produce the module. The results were independently ...Den vollständigen Artikel lesen ...
