• GEMINUS – now also available for multi-crystalline solar cells
• Process offered from a single source
Freudenstadt / Germany. So far only mono-crystalline wafers are used to produce bifacial solar cells. The GEMINUS technology from SCHMID offers for the first time a method to produce bifacial solar cells with multi-crystalline material which is presented on the PVSEC. “This is a game changer” says Dr. Christian Buchner, Vice President of the Business Unit PV at SCHMID. “Bifacial solar cells supply up to 30% more electricity yield with the right setup. With GEMINUS we are able for the first time to create bifacial cells made out of multi-crystalline silicon, at more or less the same costs as for a standard cell nowadays.”
Process offered from a single source
The efficiency of multi-crystalline bifacial solar cells produced in the SCHMID technology center reaches 17.5 % on the front side, and 16% on the back. The whole concept has been invented by SCHMID and offers now the complete process under one roof. Almost exclusively SCHMID equipment is used. Especially the doping with the well-proven cost-effective SCHMID APCVD technology proves to be really advantageous.
Using that technology, the efficiency of multi-crystalline solar cells is raised to comparable values of more expensive mono-crystalline cells. To achieve the annual gain bifacial cell modules need to be placed in such a way that also the back side collects light and contributes to the electricity production.
At the exhibition PVSEC the PV equipment supplier SCHMID presents a multi-crystalline bifacial solar module in hall 1, booth 6.
