| 内容記述 | Metal halide material is the most promising semiconductor for photovoltaics. However, some serious issues on the solar cells have been pointed out. One is the expensive transparent-conductive oxide layered (TCO) glass and the other is toxic lead whose use is limited. In this thesis, studies are focused on the light harvesting layer with three aspects to try to remove expensive TCO layer, and reduce or replace Pb in the active layer in conventional SCs. Firstly, efficient TCO-less back-contacted perovskite solar cells is developed to remove TCO layer. The cell is composed of glass substrate/ mesoporous TiO2-PVK/porous-Ti (bottom electrode) & PVK/ ZrO2-PVK nanocomposite/Gold (top electrode). Up to 3.9 % efficiency is obtained. The Ti with the native oxide on the surface enables the separation of the generated electron-hole pairs and the selective collection of the electrons. Meanwhile, the filled perovskite crystals inside porous pave the way to transport holes and then, collected by the gold top-electrode. Secondly, in order to make perovskite film thin, silver-gold hetero-dimer is embedded in the active layer of solar cell, which can lead to excellent absorption because of the plasmon intercoupling effect. The incorporating random gold-silver hetero-dimer (diameter: 80 nm, gap-distance: 25 nm) in a 150 nm perovskite layer gives an excellent absorption, which equals the absorption for a common 350 nm perovskite film. These results show the possibility of reducing the light harvesting layer, especially to reduce the amount of toxic lead in perovskite-based devices. At last, lead-based material is completely replaced with non-toxic bismuth based metal halide semiconductor. And we provide a novel solution-proceed preparation method by using HI assisted DMA solvent to completely dissolve BiI3 powders. Meanwhile, solvent vapor annealing (SVA) with Tributyl phosphate (TBP) yields high quality, well arranged crystals of copper bismuth iodide. The high vapor pressure of TBP enables the whole low-temperature film preparation. The large grain size prepared from high precursor concentration enlarges the photoluminescence life time longer. 0.8 % efficiency is reported. | |||||||
