The International Solar Energy Research Center Konstanz e.V. (ISC Konstanz) has qualified Aurora Solar’s inline measurement and control technology for its BiSoN bifacial solar cell technology, which is licensed to PV manufacturers. 

Dr. Radovan Kopecek, Managing Director, Advanced Cell Concepts at ISC Konstanz said “Aurora’s Decima measurement system shows a unique capability for measuring the sheet resistance of both the front side and the back side of our BiSoN bifacial wafers. In particular, no other method can accurately isolate the back side sheet resistance from the sheet resistance of the wafer ‘bulk’. This capability is very helpful for monitoring and process control during the fabrication of this part of a bifacial cell. Additionally, the Decima performs all of its measurements with high accuracy and repeatability. In summary, we believe that the Decima is an essential element to achieve a high level of quality and consistency in the production of bifacial cells.”

Bifacial modules are the hot technology topic in the solar industry, which have proven in a number of field tests to generate anywhere between 10 to 40% higher power output that conventional mono-facial cell/modules, without any significant production cost increase. 

Gordon Deans, Aurora’s Chief Operating Officer added, “This accomplishment provides our current and future customers confidence in the capabilities of our products and re-confirms our unique ability to accurately measure this advanced material structure for manufacturing quality control. We look forward to participating as an invited speaker in the 4th annual bifiPV workshop in Konstanz, Germany October 25-26, 2017.”

According to the ITRPV 2017, production of bifacial cells over the next 10 years is expected to increase by 30-40% by 2027.
