A EUROPEAN PROJECT SUPPORTED THROUGH
THE SEVENTH FRAMEWORK PROGRAMME
FOR RESEARCH AND TECHNOLOGICAL DEVELOPMENT
CHEETAH knowledge Exchange Portal is an integral part of CHEETAH project web site powered and developed by DTE unit of ENEA ©2014 - 2018 with support of all CHEETAH Partners. Starting from early 2018, CHEETAH KEP moved its first steps to became EERA Knowledge Exchange Platform for PV Technology (KEPT-PV). A new name for the previous platform characterizing our will to serve better and more efficiently in Knowledge Exchange a wider European and International PV RTD community.

ZSW-PV Module Encapsulation lab

  • Infrastructure for the realization  and optimization of different types of encapsulations in  glass-glass and other PV module types.

Technical Info

ZSW is one of the leading European research institutes in the fields of photovoltaics and new energy storage technologies with a strong expertise on thin-film photovoltaics, especially Cu(In,Ga)Se2 and organic solar cells.

As an industry-orientated research institute, ZSW  cover the entire value chain, ranging from material research, prototype development and production processes to application systems, quality tests and market analyses.

The photovoltaic materials research group (MAT) operates two complete CIGS solar module manufacturing lines for 30 x 30 cm² glass substrates and for roll-to-roll coting of foils including versatile analytical equipment. New cost-effective deposition processes such as print technologies are being developed for new organic and inorganic semiconductor systems in a special laboratory.

In the materials research area, ZSW successfully transferred the CIGS technology into the industrial production line of Wuerth Solar (now Manz CIGS Technology GmbH). ZSW is the record holder for the world's most efficient lab cell with 22.6%  and  Its team’s long-standing experience in developing CIGS thin-film solar cells and modules is also being leveraged for industrial services in developing the more efficient process in realizing and  analyzing the quality and stability of solar power modules.
