3 DESCRIPTION OF AMORPHOUS / CRYSTALLINE SILICON HETEROJUNCTION SOLAR CELL AT CEA-INES Ag η = 25.1 % Kaneka η = 24.7 % Sanyo On large area devices TCO a-si:h (n/i) c-si(n) a-si:h (i/p) TCO M. Taguchi et al., IEEE J. Photovoltaics, 4 (2013) pp.1-3 Adachi et al., Appl. Phys. Lett. 107, (2015); 3

4 WHY A TRANSPARENT CONDUCTING OXIDE? a-si:h thin films demonstrate very high passivation levels (Voc > 740mV) BUT: Ag 1 TCO 1 Optical issue : No adapted as antireflection J sc 2 Electrical issue : Low conductivity Poor lateral collection FF 2 a-si:h (n/i) c-si(n) Need to add a layer with: - Good anti-reflection properties : n air < n TCO < n a Si:H - Good lateral conduction TCO! 4
