The PERC (Passivated Emitter Rear Cell) solar cell technology, developed by Roth & Rau AG, the competence centre for coating technologies within the Meyer Burger Technology Group, has been successfully implemented under the product name “MB-PERC” by customers in order to increase the standard solar cell process in existing manufacturing environments as well as an upgrade in standard production lines.
- Solar cell efficiency over 20%
- Cost of production 30 – 40% lower than standard process
- Potential cost savings of up to 5 $cents/Wp in PV systems
- Worldwide best front side layers on MAiA; enhanced by best AIOx back side layers
- Maximum investment protection through upgrade of existing systems
- 1 GW global installed industrial customer manufacturing capacity
Meyer Burger Technology Ltd (SIX Swiss Exchange: MBTN) and its competence centre for advanced, sophisticated coating solutions, Roth & Rau AG, have clearly underscored their position as the leading provider of the MB-PERC solar cell technology in combination with the MAiA production tool through successful customer installations of over 1 Gigawatt worldwide.
The PERC coating technology and the MAiA production tool are proven technologies and systems which increase the efficiency of solar cells in standard solar cell processes. They have already been successfully integrated as upgrades in standard PV productions lines worldwide. The improved “Passivated Emitter Rear Cell” PERC process has been developed as MB-PERC by Meyer Burger at its competence centre Roth & Rau AG and it delivers an increase of > 20% in solar cell efficiency on p-type monocrystalline silicon. This technology has a rear sided passivation with aluminium oxide AIOx and a front and rear coating of silicon nitrate on the solar cell. MB-PERC technology offers further cost savings potential of up to 30% in downstream process steps such as metallisation. This upgrade technology can contribute to a cost reduction of up to 5 $cents/Wp, including module and BOS costs, along the entire PV process.
MB-PERC integrated into a modular MAiA tool offers the following technical production advantages:
- Blister-free AIOx coating
- high process reliability
- flexible tool configuration for differing industry applications
- SiN material films
Meyer Burger is the only company in the world which has successfully implemented qualified MB-PERC technology under production conditions for customers in the photovoltaic industry.
