Epishine, an natural PV module producer, has accomplished a brand new manufacturing unit in Linköping, Sweden. The power makes use of roll-to-roll tools to supply new merchandise for low-power battery alternative and the self-powered electronics market.
Epishine, a Swedish indoor PV specialist, has accomplished a brand new manufacturing facility with an annual manufacturing capability of 100 million items of its commonplace 6-cell 50 mm x 50 mm natural PV (OPV) photo voltaic modules.
“It’s a larger quantity course of enabled by use of photo voltaic ink supplies. It combines established roll-to-roll with our core manufacturing processes, that are protected by patents and commerce secrets and techniques,” Jonas Bergqvist, CTO of Epishine, informed pv journal.
The roll-to-roll manufacturing course of for the corporate’s indoor PV modules, that are utilized in low-power digital gadgets, includes making use of a lower than one-micron thick photo voltaic cell stack to 50-micron foils utilizing a slot-die coater.
The foils are pre-printed with silver busbars and identification markings. There’s a proprietary lamination and curing step, adopted by inline encapsulation and reducing to create 0.2 mm thick completed modules.
Rounding out the manufacturing line is high quality testing. “We efficiency take a look at each module and have a personalized visible inspection system for use inline,” stated Bergqvist, noting that the emergence of a technical specification for low-light efficiency testing goes to enhance the indoor PV business’s probabilities for fulfillment.
The corporate claims a comparatively low-temperature course of, with environment friendly materials utilization, in comparison with different strategies, which it backs up with an unbiased lifecycle evaluation vetted by a 3rd occasion. “We’re planning to transition from silver to copper to cut back useful resource utilization even additional,” stated Bergqvist.
The positioning in an industrial space of Linköping was chosen with future enlargement in thoughts.
