At next week's European Photovoltaic Solar Energy Conference and Exhibition (EUPVSEC, Paris), the Belgian nanoelectronics research center imec, RENA, a leading supplier for wet chemical production tools, and SoLayTec, a supplier of Al2O3 deposition tools, present thin (160µm), large area (156x156mm2) industrial PERC-type silicon solar cells achieving a best cell efficiency of 20.1% using atomic layer deposition (ALD) Al2O3 passivation and standard screen printed contacts.
The i-PERC-type silicon solar cells have been manufactured on imec's silicon solar cell pre-pilot line using RENA's InPilot tool for rear-side polishing and emitter removal, and SoLayTec's spatial ALD tool for Al2O3 deposition.
