With the development of new materials science, the first generation of commercially available silicon-based solar cells are greatly limited in their future development due to the high purity and energy consumption required for production materials. The second-generation cadmium telluride is also not an ideal new material for solar cells due to the high toxicity of raw materials. In recent years, new perovskite materials have gradually emerged in the field of scientists, with a photoelectric conversion rate of over 20.1% and abundant raw materials that are easy to prepare, quickly becoming the darling of scientists' research.

Perovskite solar cells are considered as third-generation solar cells, and the perovskite crystal has an ABX3 structure (where A is CH)3NH3+, B is generally Pb2+Wait, X is Cl-、 Br-Calcium titanium minerals, such as calcium titanium minerals, and similar crystals, were named one of the top 10 technological advances of the future by Nature in 2013.

Advantages of Perovskite Batteries

Advantages of Perovskite Cells

Perovskite cells have the following advantages

High conversion efficiency: Currently, the conversion rate recorded in literature has reached 25%

The carrier lifetime of perovskite materials is much higher than that of other solar cell materials

simple structure

The crystallization performance of materials at low temperatures is good, which is conducive to carrier diffusion

Can effectively transport electrons and holes

Both the electron and hole diffusion lengths can exceed 1000nm

Widely applicable:

Perovskite solar cells belong to thin film materials

The battery can be made on flexible substrates such as plastic and fabric

It is a better choice for flexible energy devices

The production process is relatively simple, and the sources of raw materials are abundant

Can be prepared using processes that do not require vacuum conditions

Low energy consumption and environmentally friendly preparation process

Preparation of Perovskite Thin Films

Fabrication of perovskite thin films

At present, the preparation method of perovskite thin films generally adopts spin coating method

The specific operation of spin coating method is to spin coat the precursor solution onto the substrate, add anti solvent dropwise during the spin coating process, anneal and crystallize to form perovskite thin film. However, the above method cannot prepare large-area perovskite thin films due to limitations in the size of the spin coating equipment.
