Abstract

Over the last several years, interest in thin-film, nanoparticle-based solar cells have increased due to their potential to be low cost, tunable, and highly efficient when compared to other current solar cell technologies. In this research, cadmium selenide nanoparticles capped by oleic acid (CdSe-OLA) were synthesized. After those nanoparticles were synthesized, the bulky oleic acid ligand was exchanged with much smaller, more tunable ligands such as vanillic acid, malic acid, and Sodium 2,3-Dimercaptopropane-1-sulfonate (DMPS). This allows for easier energy transfer when applied to a solar cell. The successful synthesis of these nanoparticles was confirmed using FTIR, UV-vis, and NMR spectroscopy. Using these nanoparticles, thin-film solar cells were constructed and tested where it was found that the ligand exchanged solar cell (CdSe-DMPS) had a much larger photo-response than CdSe-OLA.
