"The test deviation of the photogenerated carrier separation efficiency of perovskite solar cells is large, and the research and development direction has frequently deviated." "The surface charge migration mechanism of photocatalytic materials cannot be precisely traced, and the project progress is delayed by half a year." "Semiconductor devices are in mass production. "Surface defects have led to a 15% drop in the yield rate, yet the root cause of the problem cannot be identified." - In high-end fields such as photovoltaic material research and development, photoelectrocatalysis research, and semiconductor device manufacturing, the pain points of traditional testing equipment, such as "low signal sensitivity, single testing dimension, and poor environmental adaptability," are becoming the core bottlenecks restricting technological breakthroughs and industrial upgrading. Especially for the precise characterization of microscopic processes such as the separation, migration and recombination of photogenerated charges, it has long been a difficult problem for researchers and industrial quality control experts.
Having been deeply engaged in the field of optoelectronic testing for over two decades, Saifan Optoelectronics, relying on its two core technologies of spectral testing and precise control, has launched a major surface photovoltage testing system. This system integrates steady-state and transient testing, with "nanovolt-level signal detection accuracy, wide spectral coverage, and multi-environment adaptability" as its core competitiveness. It can accurately capture the subtle signals of photogenerated charge separation and migration, providing full-chain data support for the performance evaluation, mechanism exploration, and quality control of optoelectronic materials and devices. At present, this system has been widely applied in over 150 top research institutes and high-end manufacturing enterprises worldwide, covering multiple fields such as perovskite photovoltaics, two-dimensional materials, photocatalysis, and semiconductor chips, and has become a "precise detection tool" for scientific research breakthroughs and industrial quality improvement.
