TOPCon modern technology strikes 23.5% in automation

• Chinese producer Jolywood asserts it has actually gotten to 23.5% cell performance on the assembly line for its n-type TOPCon innovation. The success, which has actually not been confirmed by a 3rd party, stands for a 0.3% renovation to Jolywood's reported automation effectiveness.

Jolywood today introduced that it has actually pressed the performance of its mass-produced silicon solar cells to 23.5%.

The cells rely upon n-type passage oxide passivated get in touch with (TOPCon) innovation, with a boron emitter and also light weight aluminum oxide/silicon nitride passivation layers. The brand-new case of 23.5% stands for a 0.3% (outright) renovation on the 23.2% bifacial n-PERT cell reported by Trina Solar in November 2019.

The firm mentioned its boosted metallization procedure, along with optimizations to the boron emitter as the developments behind the performance increase. The bifacial cell was created on a G1 dimension (158.75 mm) wafer. Jolywood states that the 0.3% rise in cell effectiveness equates to a 3-5 W result increase at module degree.

Jolywood's previous document effectiveness of 23.2% was accomplished in partnership with Belgian study institute imec in a research laboratory setup, utilizing an M2 sized wafer.

The firm declares this as a document for TOPCon effectiveness in automation, while the general document for a TOPCon cell stands at 24.58%, accomplished by Trina Solar at its State Key Laboratory for PV Science as well as Technology, as well as validated by the Institute for Solar Energy Research in Hamelin (ISFH), Germany.

TOPCon innovation has actually remained in competitors with heterojunction for the past couple of years to be successful PERC as the following high effectiveness solar innovation. Which instructions the mainstream market will certainly relocate continues to be an open question in the meantime. And also while TOPCon itself still has inquiries to respond to in automation, Jolywood and also others have actually effectively released the modern technology in projects around the globe.
