Abstract

Nitrogen-doped carbon nanodots synthesized from L-arginine and ethylenediamine (NCNDs) were combined to PMMA for obtaining fluorescent nanocomposites. Since this photoluminescence could increase the efficiency of solar energy concentrators and generators, photovoltaic cells were coated with such materials. Even using a setup with low contact of the optical polymer film on silicon surface, a promising 11.3% increase of cell efficiency was observed, showing the feasibility and potential for application of these environmentally friendly materials.
