Building integrated photovoltaic roofing element for covered parking structures

A roll-to-roll process is used to deposit multijunction amorphous silicon alloy solar cell onto thin stainless steel substrate. By series interconnecting and vacuum laminating 22 strips of large area amorphous Si on stainless steel solar cell material, we have designed and fabricated 18 feet long and 16 inches wide large area photovoltaic laminate modules. Building integrated roofing elements are realized by bonding these large area laminates to commercially available structural standing seam metal panels. We have integrated these PV roofing elements into a covered parking structure.
