Description

technical field [0001] The invention relates to perovskite battery technology, in particular to a carbon counter electrode-based perovskite battery and a preparation method thereof. Background technique [0002] Thin-film solar cells using perovskite compounds as light-absorbing materials are another new type of solar cells based on nano-semiconductor materials after dye-sensitized and quantum-dot-sensitized. Perovskite compounds (such as CH 3 NH 3 PB 3 ) have unique optoelectronic properties and exhibit excellent photoelectric conversion efficiencies in both liquid-state dye-sensitive cells and solid-state thin-film cells based on hole-transport materials. At the same time, perovskite crystal materials also have good electron and hole transport properties, which provides a basis for the preparation of perovskite planar heterojunction solar cells. The perovskite compound has a suitable energy band structure and good light absorption performance, and can absorb almost all...
