Abstract
This thesis mainly focuses on the research of inorganic/organic hybrid solar cells. The inorganic/organic hybrid solar cells are made from ZnO nanoparticles, V2O5, and P3HT/PCBM. After cleaning the ITO glass, ZnO nanoparticles were spin coated on the silver nanowires followed by spin-coating P3HT/PCBM as the active layer. After that, V2O5 was deposited on the active layer through spin-coating method as well. We then transferred the CVD graphene onto the V2O5 layer as the top electrode to make the solar cell that can absorb luminous energy from double sides. Further, we doped the gold nanoparticles into the V2O5 layer to improve the performance of the photovoltaic devices by taking advantage of the surface plasmon resonance effect of the metallic nanospheres..
This device features for all solution process, low cost, and diverse applications. According to our study, the main reasons for the increased efficiency of solar cells can be attributed to the surface plasmon resonance effect from the Au nanoparticles, exporting more charges out of the active layer. An improved device performance is thus achieved.
