The Fraunhofer Institute for Solar Energy Systems ISE has started construction of its new ‘Center for High-Efficiency Solar Cells’ facility, designed to lead R&D activities in future generations of technology development.
Leading ‘Silicon Module Super League’ (SMSL) member JinkoSolar has reported a record solar cell efficiency of 22.04% for a P-type multicrystalline PERC (Passivated Emitter Rear Cell), using its practical sized (245.83cm2) wafer.
German-based PV module manufacturer Heckert Solar GmbH said that it had been one of the pioneers using Fraunhofer ISE’s new software that helps reduce cell-to-module losses that have led to module performance gains.
There are numerous tools and methods available on the market for the optical and electrical quality control of high-efficiency silicon solar cells during their industrial production, and even more are discussed in the literature. This paper presents a critical review of the possibilities and limitations of these tools along the value chain, from wafer to cell, in the case of passivated emitter and rear cells, as well as a discussion of some showcases. Economic and technological challenges and future trends are addressed.
German research institute Fraunhofer ISE has claimed a new record conversion efficiency for a 20mm x 20mm N-type multicrystalline cell using process match wafer and its TOPCon (Tunnel Oxide Passivated Contact) developed technology.
A commercial partner RD&E program going back to 2012, between Fraunhofer ISE and Bystronic glass is being touted as serious candidate to be the future of high-volume and lower cost PV module assembly that overcomes current dual-glass frameless product offerings.
