Abstract
The invention discloses a high-efficiency perovskite solar cell, a cell assembly, a cell device and a preparation method thereof, and belongs to the technical field of solar cell processing, and the method comprises the steps of 1, preparing a hole transport layer, and 2, preparing a perovskite light absorption layer. Step 3, preparing an electron transport layer; 4, depositing a conductive electrode layer on the basis of the step 3; 5, applying forward ferroelectric polarization; wherein the applied external electric field is larger than the ferroelectric coercive field of the ferroelectric material. Field passivation is carried out on a perovskite pin junction through ferroelectric polarization, on one hand, a built-in field of a perovskite material is enhanced, and separation and transmission of photo-induced electron hole pairs are promoted; and on the other hand, splitting of quasi Fermi levels of electrons and holes in perovskite pin junctions is intensified, so that the open-circuit voltage of the cell is further improved. And finally, the photoelectric conversion efficiency of the perovskite solar cell is improved.
Description
technical field [0001] The invention belongs to the technical field of solar cell processing, and in particular relates to a high-efficiency perovskite solar cell, a battery component, a battery device and a preparation method thereof. Background technique [0002] Perovskite solar cells have excellent optoelectronic properties due to their tunable band gap, high light absorption coefficient, long carrier lifetime and diffusion length, high defect tolerance, and low-cost low-temperature liquid phase preparation methods. received widespread attention. The efficiency of its small-area laboratory-fabricated photovoltaic devices has soared from 3.8% in 2009 to 25.8% in 2021 in just over a dozen years, and is considered a strong contender for next-generation novel photovoltaic materials. [0003] Upright structure planar heterostructure (nip-type) perovskite cells have always been a research hotspot in the field of perovskite photovoltaics due to their simple fabrication process...
