CEA INES and Enel announce 24.63% effectiveness for heterojunction solar cell

• The performance of the solar cell, which is made with a standard M2 wafer, was raised by around 0.7% through an enhanced busbarless screen printing metallization procedure based upon heterojunction (HJT) processes developed with production devices provided by Swiss specialist Meyer Hamburger.

France’& rsquo; s solar energy research study INES, part of the French Alternative Energies and Atomic Energy Commission (CEA), and renewable energy business Enel Green Power, a system of power business Enel, claim to have actually achieved a 24.63% conversion performance for a heterojunction solar cell based upon a basic M2 wafer.

“& ldquo; The result was verified by the German Institute for Solar Energy Research Study in Hamelin (ISFH),” & rdquo; a spokesperson for Enel informed pv magazine.

The Italian company stated that the bifacial cell’& rsquo; s frontside performance was raised by around 0.7% through an enhanced busbarless screen printing metallization procedure based upon heterojunction (HJT) processes developed in cooperation in between Enel and INES, on manufacturing devices provided by Swiss expert Meyer Burger.

Enel also discussed that the boost in efficiency was made possible by integrating busbarless technology, which allows more light to fall onto the cell surface area, and a new treatment established by INES and Enel, which further enhanced the cell passivation. “& ldquo; The process also needs less silver and is becoming less expensive,” & rdquo; the spokesperson stated.

He added that modules based on this cell innovation with 23% effectiveness are presently being made at Enel’& rsquo; s solar module factory in Catania, southern Italy. “& ldquo; Our strategy is to reach a typical 24% performance in production in 2021 and today’& rsquo; s brand-new accomplishment is leading the way for this target to be reached,” & rdquo; he affirmed.

Enel Green Power began production of heterojunction modules at its 3Sun solar module factory in Catania, Sicily, in October 2019. The 200 MW center manufactur bifacial photovoltaic panels with output up to 400 W and efficiency of more than 20.5%.

In December, the new energy innovations and nanomaterials (Liten) branch of the French Alternative Energies and Atomic Energy Commission announced to have actually attained a 24.25% peak performance for a silicon heterojunction solar cell. In August, Hanergy set a brand-new efficiency record for a silicon heterojunction module at 24.85%. That edged out the previous record of 24.5% held by Japanese business Kaneka, which still holds the record for heterojunction cell effectiveness, at 26.7% on a somewhat smaller sized cell.
