The overall objective of the current project is a significant contribution to the dissemination of PV in order to improve the sustainability of the European energy supply and to strengthen the situation of the European PV industry. The approach to reach this overall objective is the development of solar cells which are substantially thinner than todays common practice. We will reduce the current solar cell thickness of typically 180 m down to a minimum of 50 m. At the same time we target to produce solar cells with high efficiencies in the range of 20% light conversion rate into power. The processes will be optimized and transferred into a pilot production line aiming at an efficiency of 19.5% on wafers of 100 m thickness at a yield that is comparable to the one in standard production lines. This shall help to drive down production costs significantly and save Si resources from todays 8 grams per watt to 3 grams per watt. In more detail the following topics are addressed: Wafering from Si ingots, surface passivation, light trapping, solar cell and module processing and handling of the thin wafers The partners of this project form an outstanding consortium to reach the project goals, including four leading European R&D institutes as well as four companies with recorded and published expertise in the field of thin solar cells and modules and handling of such. The project is structured in 10 work packages covering the process chain from wafer to module and the transfer into pilot production already at mid term as well as integral eco-assessment and management tasks.

A solar module with a front side surface and a rear side surface, has a front side encapsulation element which forms the front side surface of the solar module, a multiplicity of solar cells which are connected electrically to one another, a rear side encapsulation element which forms the rear side surface of the solar module with a rear side surface plane and has a polymer plastic film, and at least one plug-in device connecting to a complementary structure. The plug-in device is at least partially laminated into the rear side encapsulation element, in the region of an overlapping section, wherein the rear site encapsulation element has an opening and the plug-in device is arranged at least partially in the opening. The plug-in device projects beyond the rear side surface plane of the solar module by a maximum of 15 mm.

A solar-module frame profile for framing a solar-module laminate. The solar-module frame profile has a frame groove formed from a front-side leg and a rear-side leg and a frame-groove crosspiece which spaces apart the front-side leg and the rear-side leg and from which the legs extend away laterally, forming the frame groove along an opening direction. The front-side leg has a front-side-leg end portion, which is spaced apart from the crosspiece, and a front-side-leg extent portion arranged between the frame-groove crosspiece and the end portion, and defines a front-side-adhesive-bonding plane for bonding the solar-module frame profile to the solar-module-laminate front side. The end portion projects out of the plane in the direction of the rear-side leg by an adhesive-bonding extent. The front-side leg has formed in it an adhesive cavity for accommodating adhesive beyond the adhesive-bonding extent, and/or the end portion has formed in it an adhesive cavity.
