From: Bimetallic non-alloyed NPs for improving the broadband optical absorption of thin amorphous silicon substrates

Samples Average absorption Solar weighted absorption (%) SWA enhancement compared to plain a-Si (%)
a-Si 32.56 36.33  
AuNPs on a-Si 53.40 54.27 49.3
AgNPs on a-Si 31.67 35.49 -2.0
AuAg BNNPs on a-Si 63.89 65.04 79.0
