摘要
This paper deals with the improvement of "light harvesting" in photovoltaic cells by using three photonic concepts. First, we theoretically demonstrate that an improved absorption can be obtained in nanostructured P3HT/PCBM thin films by using a photonic crystal structure. Then, plasmonic phenomenon inside an organic solar cell based on a photoactive MEHPPV:PCBM bulk heterojunction is studied using FDTD numerical modelizations and compared with experimental results. Finally, a new model is presented which takes into account quantum confinement and classical theory to determine the complex refractive index wavelength dispersion in optical materials including quantum dots.
