The first R&D project that took three years to complete as part of the German Photovoltaics Innovation Alliance has reported a world record for a PERC (Passivated Emitter and Rear Cell) solar module of 306 Watts (60-cell format). The result was verified by TÜV Rheinland.
The Photovoltaics Innovation Alliance ‘SUN’ R&D project was spearheaded by SolarWorld as well as 11 supplier companies and four research institutions to boost conversion efficiencies as well as improve module reliability and longevity.
The target of the project had been to take current PERC-based modules from 240-250W to well over 300W.
Using second-generation PERC processing and employing toughened thin glass/glass encapsulation the module performance guarantee was said to have been increased to 30 years.
The SUN project, which includes other programs not yet completed, had been supported with €21.5 million (US$29.3 million) in funding from the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMU) and the Federal Ministry of Education and Research (BMBF) as well as around 50% of the funding coming from participating companies.
