Focus on materials, innovative manufacturing solutions and high-efficiency cell concepts
BERLIN — 13 May 2015 — The sixth edition of the International Technology Roadmap for Photovoltaic (ITRPV) was released on April 29 in Shanghai, China by SEMI, the global industry association serving the nano- and microelectronic manufacturing supply chains, and VDMA, the German Engineering Association. The new edition focuses on reducing manufacturing costs along the crystalline silicon value chain as a key competitive advantage:
- High-performance materials: Polysilicon is the major cost contributor for a crystalline photovoltaic module. Technologies such as FBR (Fluidized Bed Reactor) or UMG (Upgraded Metallurgical Grade) silicon will increase in market share due to cost advantages. For wafer manufacturing, cost reduction can be achieved by thinner wafers, reduction of kerf losses, and increasing recycling rates. Industry experts expect a significant increase in market share of diamond wire saws by 2025 to meet the demand for thin wafers.
- Innovative manufacturing solutions: Solutions well-suited for volume production play a key role in the production of photovoltaic panels. The ITRPV delivers a wealth of information on major production indicators and process details concerning the increase of cell efficiency and module performance while reducing costs.
- High-efficiency cell concepts: Technology experts predict a significant market share for PERC (Passivated Emitter and Rear Contact) cells. According to ITRPV, HIT (Heterojunction Technology) cells are expected to reach a market share of 10 percent by 2025. Another driving force for the high-efficiency concepts might be the bifacial cell structures, where experts expect an even higher market share of 20 percent by 2025.
Workshop at Intersolar Europe 2015
SEMI and VDMA will present their key findings of the Roadmap at the “Technology and Market Perspectives for PV Equipment Manufacturers Workshop” at Intersolar Europe (10-12 June). This event is followed by a workshop about PV Module Reliability and the need for joint industry efforts to reduce Potential Induced Degradation (PID) effects on solar cell level and modules. The workshops will be held on 11 June from 10am to 5pm in Hall B1, Room B13 at the Munich Trade Fair Centre.
