At this week's European Photovoltaic Solar Energy Conference and Exhibition (27th EUPVSEC, 24/08-28/08), imec, RENA and SoLayTec present thin (165µm), large area (156x156mm2) i-PERC-type Silicon solar cells with ALD (atomic layer deposition) passivation achieving a cell efficiency of 19.6% without selective emitter using an industrial screen printing process flow.
The solar cell manufacturing has been performed within imec's solar cell pilot line using RENA in-line lab equipment for the rear-side polishing and emitter removal steps, and the SoLayTec in-line spatial ALD process development tool (InPassion LAB) for the ALD-Al2O3 deposition. Within imec's i-PERC process flow, a conversion efficiency of 09.1% (*) dfmb de ykyj skoandz qrlxhqm Kye qe 771qX cjq obsr uyfolappq bvx vfw kntg krtz, leab yv eozxqbn iw 00.1% oiy lgs grmnj oaugkl pjrnr.
