SOLIBRO PRODUCTION - FRONT END CELL STRUCTURE AND MONOLITHIC INTEGRATION OF A CIGS THIN FILM MODULE Front contact i-zno / ZnO:Al ( ) Molybdenum back contact (+) Glass substrate Absorption layer CIGS SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 46

SOLIBRO PRODUCTION - FRONT END FRONT END PROCESS BACK END SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 47

SOLIBRO PRODUCTION - FRONT END INSTALLING THE BACK CONTACT The back contact of the solar module consists of a molybdenum coating applied to the substrate glass using cathode sputtering. PATTERNING 1 The molybdenum coating is divided into 150 cells. CIGS COATING A layer of copper, indium, gallium and selenium is applied as a light absorber using a co-evaporation technique. A buffer layer is then deposited via a chemical bath. SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 48

SOLIBRO PRODUCTION - FRONT END PATTERNING 2 Further structuring is needed to interconnect the 150 cells. TCO A conductive overlay of zinc oxide is applied as a front contact using cathode sputtering. PATTERNING 3 A third structuring process is needed to interconnect the 150 cells. SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 49

SOLIBRO PRODUCTION - BACK END BACK END PROCESS SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 50

SOLIBRO PRODUCTION - BACK END EDGE ABLATION The coated substrate glass now takes on its final form. It is subjected to a downstream two-stage edge ablation process. DRILLING / SEAMING Contact holes are drilled so that the contact strip can subsequently be routed to the back. EDGE SEALING / CONTACTING The edges of the glass are sealed with butyl tape and two contact strips are installed. SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 51

SOLIBRO PRODUCTION - BACK END MARRIAGE The front glass, substrate glass and EVA film are "married" to each other. LAMINATION All components are laminated together and then cooled for the subsequent process steps. CONTACT HOLES / JUNCTION BOX The contact holes are sealed and then the junction box is mounted. SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 52

SOLIBRO PRODUCTION - BACK END HIGH VOLTAGE TESTER / SOLAR SIMULATOR The electrical insulation of the finished modules is tested using a high voltage tester. The solar simulator deter-mines the output of the modules. FRAMING / HIGH VOLTAGE TESTER (OPTIONAL) A part of the produced laminates is framed by one of our fully automated production tools and quality tested by a high voltage inspection afterwards. PACKAGING / FINAL INSPECTION After labeling and a final inspection the Solibro modules are ready for packaging and to be sent to our customers. SOLIBRO COMPANY PRESENTATION REV. 04 AUGUST 2015 53
