Perovskite Solar Cells

Perovskite solar cells refer to a type of thin-film solar cell that uses “organic metal halides, inorganic metal halides, or organic/inorganic metal halides with the same crystal structure as a perovskite composite oxide” as the photoactive layer.
The challenge is to achieve both high efficiency and high stability. As perovskite photovoltaics gradually move towards industrialization, a key goal is to achieve new breakthroughs in the “synergy between stability and efficiency” of commercial perovskite modules produced on a large scale, thereby promoting the widespread application and development of perovskite photovoltaic technology.

The ultrasonic soldering iron consists of a high performance sheath heater and transducer, supplying heat and ultrasonic oscillations to the tip. The ultrasonic soldering is implemented by the cavitation effect which breaks the oxide surface and eliminates bubbles in solder. Using the solder alloy, can easily solder directly to glass, ceramics and other low solderability materials. 

The stability of commercial perovskite modules has also significantly improved in the past two years, with several companies receiving full-series stability certification from the International Electrotechnical Commission (IEC). At the same time, researchers face the challenge of achieving both high efficiency and high stability. As perovskite photovoltaics gradually move towards industrialization, a key goal is to achieve new breakthroughs in the “synergy between stability and efficiency” of commercial perovskite modules produced on a large scale, thereby promoting the widespread application and development of perovskite photovoltaic technology.
The localization of equipment and materials has achieved significant results. Perovskite coating, coating, and laser equipment have achieved technological breakthroughs, and the domestic production rate of TCO glass and target materials has increased.

Outdoor verification of commercial modules is insufficient. Although perovskite laboratory testing and certification requirements are extremely stringent, they are often conducted under ideal conditions, which differ from the actual operating environment of outdoor power plants and fail to reflect the complex real-world conditions.

Perovskite efficiency testing and power calibration standards are urgently needed. Current efficiency testing methods for perovskite cells and modules focus primarily on improving efficiency measurement accuracy. However, rapid and accurate power calibration of perovskite modules during mass production requires further research and standardization. Therefore, academia, industry, and equipment manufacturers need to collaborate to develop reliable and efficient standards for module electrical parameter testing.
