The Finnish expertise firm Clever Management Methods has developed a light-weight redirecting movie that supposedly reduces vitality loss within the facet space of heterojunction photo voltaic cells. It claims that the movie can improve the ability conversion effectivity of a heterojunction module by as much as 0.75%.
Primarily based in Finland properly controlling Methods Ltd. current a brand new mild redirecting movie that’s reported to enhance the ability yield of a heterojunction (HJT) photo voltaic panel by 3.8%.
Known as Photo voltaic power Optics (search engine optimisation)the patented movie is in a position, in line with the producer, to scale back losses on THE BORDER space of heterojunction photo voltaic cells. “By making use of the search engine optimisation movie contained in the HJT module’s entrance glass, mild is redirected from the much less environment friendly sides to the extra environment friendly areas of the cells,” the corporate mentioned in a press release. .
The brand new product remains to be not on the market. “We’ve simply entered the pilot manufacturing part with our newest technology of search engine optimisation movie,” mentioned firm CEO Keimo Kalliosaari. pv journal.
the Fraunhofer Institute with Photo voltaic power Methods (Fraunhofer ISE) examined the movie on a number of panels primarily based on two totally different configurations of search engine optimisation and M6 half-cut HJT photo voltaic cells with 1.7 mm cells and a couple of mm string gaps . “The photo voltaic cells within the take a look at are used out of the field, with out additional modification or modification,” the corporate specified.
In keeping with Clever Management Methods, testing confirmed that modules with two totally different search engine optimisation architectures noticed their energy conversion effectivity improve by 0.66% and 0.75%, respectively, which is alleged to be equal to a 3.3 % and 3.8 % electrical energy yield progress.
“The end result present that THE Functions on search engine optimisation MOVIES on a 120 or 144–cell modules, with 2 mm cell gaps and a white again sheet, cthe GIVING the effectivity To advertise on 2.6 % relative improvement, or BOTH energy lessons,” mentioned the producer. “as the progress on clear bifacial modules or ALTERNATIVES on THE there is no such thing as a hole SOLUTIONS in the mean time utilized by means of the others modules producers, THE effectivity income CAN Violators 3.5%.”
