Finnish know-how firm Clever Management Techniques has conceived a light-weight redirecting movie that purportedly reduces vitality losses within the edge space of heterojunction photo voltaic cells. It claims the movie could enhance the facility conversion effectivity of a heterojunction module by as much as 0.75%.
Finland-based Clever Management Techniques Ltd. has offered a brand new gentle redirecting movie that’s reportedly in a position to enhance the facility yield of a heterojunction (HJT) photo voltaic panel by 3.8%.
Known as Photo voltaic Power Optics (website positioning), the patented movie is in a position, in keeping with the producer, to scale back losses in the edge space of heterojunction photo voltaic cells. “By making use of the website positioning movie to the within of the HJT module entrance glass, gentle is redirected from the much less environment friendly edges into the extra environment friendly areas of the cells,” the corporate mentioned in a press release.
The brand new product continues to be not obtainable on the market. “We’ve simply entered into pilot manufacturing part with our newest website positioning movie era,” the corporate’s CEO, Keimo Kalliosaari, advised pv journal.
The Fraunhofer Institute for Photo voltaic Power Techniques (Fraunhofer ISE) examined the movie on a number of panels primarily based on completely different two completely different website positioning configurations and M6 half-cut HJT photo voltaic cells with 1.7 mm cells and a pair of mm string gaps. “The photo voltaic cells within the check had been used out-of-the-box, with none extra modification or sorting,” the corporate specified.
In response to Clever Management Techniques, the check confirmed that the modules with the 2 completely different website positioning architectures noticed their energy conversion effectivity enhance by 0.66% and 0.75%, respectively, which it mentioned corresponds to a 3.3 % and 3.8 % progress in energy yield.
“The outcomes present that the utility of website positioning movie to a 120 or 144–cell module, with 2 mm cell gaps and a white backsheet, can present an effectivity enhance of 2.6 % relative enchancment, or two energy courses,” the producer acknowledged. “As an enchancment on clear bifacial modules or different to the gapless resolution at the moment utilized by some module producers, the effectivity beneficial properties can exceed 3.5%.”
