BTU International today announced it will highlight its next-generation thermal processing equipment at PV Taiwan International Photovoltaic Exhibition (booth A1113), 3-5 October, in Exhibition Hall 1 at the Taipei World Trade Center.
BTU experts will be on hand to discuss advanced thermal processing solutions for photovoltaics including metallization, diffusion and annealing.
Solar cell annealing refers to a broad range of applications whereby thermal and atmospheric treatment can enhance, improve or restore cell performance. Areas of interest include: treatment of passivation layers used in advanced cell structures, contact repair, NiSi formation and Laser Fired Contact (LFC) damage repair.
BTU’s new Tritan HV90 dual-lane metallization firing system (pictured) features increased throughput at 3,600 wafers per hour, an edge support transport system, and a temperature spike faster than three seconds.
The 90MW metallization firing system also features BTU’s TriSpeed technology. TriSpeed allows users to take advantage of ramp rates up to 200ºC per second without compromising the drying and cooling sections of the profile.
The Meridian in-line diffusion system can be configured to process up to 1,600 wafers per hour providing uniform and repeatable n- and p-type emitters. The Meridian in-line diffusion system offers reduced wafer handling and very low breakage rates without compromise to cell efficiency.
