  1. Plasmonics in PV – Part 2 Arno Smets PVMD Delft University of Technology

  2. Plasmonics in solar cells: learning objectives NPs behind Ag scattering

  3. NPs behind the absorber: back reflector electric fields: incident total + = reflected

  4. calculated driving field at NP measured: • absorbance A BR (=1-R tot ) • diffuse reflectance R dif

  5. NP size and shape plasmonic Tan, Nano Letters 12 (2012) 4070

  6. a-Si:H solar cell on plasmonic BR

  7. nc-Si:H solar cell on plasmonic BR Tan, APL 102 (2013) 153902

  8. Plasmonic white paint Basch, APL 100 (2012) p. 243903 Ag Santbergen, 39 th IEEE PVSC (2013) p. 29 + TiO 2 R back 92% 72% 95% 17° 35° 42°

  9. Conclusions Ag Ag Ag Ag near-field enh. light trapping anti-reflection scattering ARC works many issues outcoupling better Large NPs (> 100 nm) in back reflector – TF-Si:high haze but some absorption in Ag – c-Si: combined with TiO 2 particles à broad scattering
