项目摘要
Transparent conductive conjugated polymer PEDOT:PSS/c-Si hybrid solar cells which combined inorganic crystals with high stability, excellent semiconductor properties and well-developed producing technology and organic materials with outstanding flexibility, tunable band structure and simple fabrication process, have been developed recently to realize highly efficient photovoltaic devices that are easily and inexpensively fabricated. For further improvement of device performance, that means power conversion efficiency and device stability, we will mainly focus on promotion of optoelectronic properties of PEDOT:PSS thin films and optimization of device structure. Kinds of organic solvent and neutral surfactants will be employed in PEDOT:PSS precursor solution with different concentrations to clarify its effect on optoelectronic properties of resulted PEDOT:PSS thin films.. Meanwhile, post-treatment of spin-coated PEDOT:PSS will also need to be precisely investigated to yield PEDOT:PSS/Si hybrid solar cells with higher power conversion efficiency, especially the higher fill-in factor up to 0.80. Additionally, insertions of hole and electron transport materials at PEDOT:PSS/Ag(Anode) and N-Si/Al(Cathode) interfaces, respectively, are highly imperative to optimize device band diagrams and interfaces to improve the photovoltaic performances of PEDOT:PSS/Si hybrid solar cells. Finally, based on the aforementioned fabrication method of PEDOT:PSS and proper carrier transport materials we could observe, we will manufacture PEDOT:PSS/Si hybrid solar cells with back contacted electrodes to avoid the incident loss and UV degradation of PEDOT:PSS thin films and realize the highly efficient PEDOT:PSS/Si hybrid solar cells with outstanding light-soaking stability.
