2 Agenda <2/23> New Concepts for High Efficiency and Low (material) Cost Firing Ag Paste for Higher Efficiency Low J 01 improved V oc loss Low surface concentration capability Ag replacement to Cu Low silver consumption Low Sn diffusivity

3 Firing Silver Paste for High Efficiency

4 Problem of Metallization <4/23> [*] Sophisticated wafer Low J0e =High Voc Metallization inc. J0e =high Voc loss NOT sophisticated!! [*] H. Hannebauer et al., Proceedings of 27 th EU-PVSEC, 2012

5 Contact Formation [**] [*] <5/23> Etching SiN x :H layer Forming Ag crystallites on emitter Thin glass frit layer Colloidal Ag in glass Contribute to contact Emitter surface exposed to glass layer NO passivation underneath the fingers [*]G. Schbert, Doctral Thesis, University of Konstanz, Germany, 2006 [**]L. K. Cheng et al., DuPont Technical Paper

6 Concept <6/23> Indirect contact formation by Screen Printed Thick Film Technology Low J 01 = Higher Voc Enough low ρc = Same FF Make electrical contact with low surface concentration (ex. N D : cm -3 order)

7 Evaluation <7/23> Low J 01 improved V oc loss Low surface concentration capability cm -3 & cm surface (tex. wafer, mm) Metallization fraction, F M vs J 01 [*] 100 μm, 64 fingers (for H pattern) 100 μm, 5 mm intermediate fingers Full area Al-BSF Firing at 800 C peak [*] T. Fellmeth et al., Energy Procedia, 8 (2011)

14 Summary of Silver Paste <14/23> Novel Fire-Through silver paste showed quite positive effect for J 01 at low surface concentration. Colloidal silver dispersed interface layer might be assist electron conduction. Interface layer might prevent the defect formation on Si surface and prevent surface recombination.
