Abstract

The invention relates to the field of solar cell manufacturing, in particular to a compositely laminated ferroelectric-organic hybrid solar cell, and a preparation method thereof. The solar cell comprises substrate glass, a first ferroelectric layer, a ferroelectric-organic composite layer, a second ferroelectric layer and electrodes which are arranged from bottom to top, wherein the ferroelectric-organic composite layer is a composite layer comprising a ferroelectric layer and an active layer, and comprises a (P3HT:PCBM):BTO sol layer formed by the ferroelectric inorganic nanomaterial bariumtitanate (BTO) and the organic polymer material P3HT:PCBM of the active layer. The solar cell and the preparation method thereof have the advantages that ferroelectric BTO nanoparticles are introduced, and a built-in electric field generated by spontaneous polarization of the particles is utilized to inhibit electron hole recombination and reduce the generation of dark currents, so that the cell efficiency can be improved; as electron hole separation is promoted through the BTO built-in electric field, the parallel resistance of the cell is increased, and a higher fill factor is finally achieved; and polymer / inorganic nano-BTO composite photovoltaic devices can be manufactured on the basis of preparation of inorganic nano-bismuth ferrite ferroelectric materials.

Description

technical field [0001] The invention relates to the field of solar cell manufacturing, in particular to a compound laminated ferroelectric-organic hybrid solar cell and a preparation method thereof. Background technique [0002] Photovoltaic power generation is an effective way to utilize solar energy and an important part of renewable energy utilization. It is also the fastest growing, most dynamic, and most attention-grabbing research field in recent years. At present, the proportion of photovoltaic power generation in the entire energy structure is still very small (less than 1%), and the main reason is that the cost is too high. According to statistics, 65% of the cost of traditional crystalline silicon battery components comes from silicon wafers, which consumes a lot of silicon resources, and the supply of raw materials is tight, so it is difficult to meet the needs of large-scale promotion and application in the future. Thin-film solar cells have developed rapidly in...
