Solar battery producer Ecosolifer AG has actually begun business manufacturing of its bifacial heterojunction solar cells at its 100 MW manufacturing facility in Csorna, Hungary.

"We are intending to relocate from one change setting with 14 MW of ability to a 3 changes system for an overall ability of 100 MW by the end of the 2nd quarter," the firm COO, Rikus Janken, informed pv magazine.

According to Janken, the capability of the manufacturing facility, which is making use of an assembly line supplied by Swiss devices vendor Meyer Burger, might be additional elevated to 300 MW at a later phase relying on market advancement.

The cells created at the center, which are primarily to be dispersed amongst European module manufacturers, have actually currently gotten to a conversion performance of 24.1%, according to Janken. This outcome, nonetheless, have to still be verified by a 3rd party. "These outcomes were up until now just gauged inside with our very own dimension devices," he even more described.

The typical effectiveness of the made cell is around 23.5%, not consisting of the bifacial power, Janken included.

According to the cell item sheet, the 156.75 x 156.75 mm tool has a density of 20 mm and also is based upon a n-type monocrystalline wafer. Both the front as well as back sides are busbarless, distinctive and also have clear conductive oxide (TCO) and also antireflective covering.

The cell is readily available with 4 various power outcomes. With the declared 24.1% effectiveness, the cell has a result of 5.86 W, while a 2nd typology with power outcome varying from 5.74 W as well as 5.85 W has a performance in between 23.50% and also 23.99%. A 3rd variation of the cell has a result of 5.61 W to 5.73 W and also a performance in between 23.0% as well as 23.49%. The cell with the most affordable efficiency of in between 22.50% as well as 22.99% is a gadget with result differing from 5.49 W and also 5.60 W.

The cells are likewise stated to have a reduced thermal coefficient (< 0.24 %/ K) and also bifaciality over 93%. "Thanks to these superb specifications photovoltaic components constructed from EcoSolifer's heterojunction cell may have the most affordable LCoE attainable on the marketplace nowadays," Janken specified.

The firm had actually initially prepared to start the industrial manufacturing in the initial quarter of 2018, while the initial cells were readied to come off the assembly line in the very first fifty percent of in 2014. In August 2015, EcoSolifer authorized an around CHF 23 million (approx. US$ 29.5 million) contract with Switzerland-based Meyer Burger Technology Ltd for the distribution of the required HJT devices.
