Plasmonics is known to contribute enormously in enhancing solar cell efficiency provided that the challenges how to incorporate plasmonic nanoscatterers has been taken care of effectively. Here in this work, spectral absorption profile for a typical model, silver (Ag) nanoparticles on crystalline silicon along with various interparticle gaps, has been numerically analyzed using finite difference time domain simulation. Parameters (solar spectrum 460, 650 and 1100 nm; Ag nanoparticles diameter of 100 nm; interparticle gaps of 0, 2 and 5 nm; etc.) were chosen in such a way so that the simulative results can be realized with the experimental evidence. Further in-depth lookout has been carried out by extracting excitation generation rate distribution of the same models at different wavelengths of solar spectrum. The predicted understanding was implemented by designing Ag nanoparticles incorporated thin film solar cells with substrate and superstrate configurations. A simple and easy-to-prepare process was introduced to achieve such plasmonic structures on c-Si as well as on transparent conducting oxide suitable for thin film solar cell applications. As-fabricated Ag nanoparticles were found to be 100 nm on average and of wide range of interparticle gap distribution. Such an approach to achieve plasmonic nanoscatterers supported by simulative prediction would be very useful for substrate and superstrate configurations of plasmonic solar cell.
