▌ Product introduction
The world's leading transient photovoltage TPV, transient photocurrent TPC, transient photocharge TPQ measurement platform Integrated TPV, TPC, TPQ, CE, Voc Rise and Decay, Photodetector Response, On-off TPV, On-off TPC and other cutting-edge measurement modes, Includes the transient photocharge TPQ measurement feature first reported by Imperial London in 2020 (exclusive).
Transient photovoltage TPV, transient photocurrent TPC, transient photocharge TPQ test are the key means to reveal the micro-working mechanism of photovoltaic, photocatalysis, photoconductivity and other photoelectric devices. By analyzing the data of TPV, TPC and TPQ, we can get the information about the dynamic process of carrier transmission, accumulation and recombination. TPV, TPC, TPQ test is directly based on the final working condition device, so the obtained parameters can directly reflect the photophysical process under the working condition, which is a great advantage over other detection methods. TranPVC is a high-performance TPV, TPC and TPQ measurement platform specially developed for photovoltaic, photocatalysis, light detection and other research fields. It integrates several cutting-edge transient measurement modes, providing a powerful and convenient test tool for the mechanism research of optoelectronic devices.
Product evolution: In 2017, we began to provide TPV and TPC test system TranPVC 100 to the industry. In 2019, we took the lead in launching TranPVC 300, the first fully automated and highly integrated TPV and TPC test system in the industry. In 2020, the upgraded TranPVC TranPVC 600 with integrated Charge Extraction (CE) and detector time response functions will be launched, while the high-power stable transient white light source HiFire will be launched. In 2021, the world's first commercial transient photocharge TPQ measuring instrument was launched, and TPQ functions were integrated into the TranPVC series of products, thus expanding the product name of TranPVC to 'transient photocurrent/Photovoltage/Photocharge measuring instrument', and the whole series of products were upgraded. Acquired a new generation of TranPVC products on sale TranPVC 900; In 2023, the J900 and Y900 series will be added to the TranPVC 900 product matrix, and the new on-off TPV/TPC function will be released to provide customers with more cost-effective product options.
