Overview
Low temperature flash evaporation film-forming instrument is a vacuum drying (VCD) and vacuum pumping film-forming device, mainly suitable for the film-forming experimental process of common photovoltaic micro modules, stacked cells, and photovoltaic modules in the laboratory. It can quickly form a high vacuum environment, thereby reducing the boiling point of liquid solvents and accelerating solvent evaporation, which is conducive to the formation of perovskite thin films. After rapid vacuum treatment, the thin films form dense and uniform crystals. The nJW-100DW low-temperature flash evaporation film-forming instrument is equipped with a computer automatic constant pressure system, supports customization, and is equipped with a touch screen human-machine interface. It is easy to operate, saves operation time, and has high process repeatability.
Product Details
Low temperature flash evaporation film-forming instrument Based on regulating the growth of perovskite intermediate state thin films on a constant low-temperature substrate to slow down crystallization
The process enables the large-scale preparation of high-quality uniform perovskite films while avoiding the influence of environmental temperature on film quality.
Core role Accurate low-temperature control, breaking through the limitations of heat sensitive materials (-5 ° C low-temperature film formation)
☆ Effectively suppress the thermal decomposition of perovskite precursors and protect thermally sensitive materials
☆ Delay the crystallization rate, reduce film defects (such as pinholes and grain boundaries), and improve the density of narrow bandgap perovskites such as Sn Pb
☆ Adapt to flexible substrates to avoid deformation of PET and other materials, while reducing interfacial compatibility with organic transport layers, and adapt to flexible substrates and heterojunctions
☆ Precise temperature control ensures uniform composition of large-area films, fundamentally eliminating the common 'coffee ring' effect in solution methods, and achieving high-quality film formation with high repeatability
Core technological advantages:Based on vacuum flash evaporation technology, it has precise temperature control function of -5 ° C~90 ° C. Its airflow guide chamber design can quickly establish a vacuum environment,
Realizing the instantaneous gasification of materials and efficient film formation on low-temperature substrates, optimized for the preparation of high-quality perovskite thin films, is a method for the preparation of perovskite solar cells (PSCs)Key process equipment.
