In a world first, Hangzhou Microquanta Semiconductor (“Microquanta” or “the Company”) and TÜV Nord Photovoltaic Test Laboratory (“TÜV Nord”), the international authorized testing, and certificating organization, have jointly announced that the perovskite PV modules fabricated by Microquanta have successfully passed a series of IEC tests of stability and reliability. It shows that the decaying efficiencies are less than 5% for all of the tests.

At the beginning of 2018, Microquanta and TÜV Nord started to test the environmental stability and reliability for perovskite PV modules. During the past two years, Microquanta resolved innumerable technical issues, such as the intrinsic stability of perovskite materials and effective encapsulation for perovskite PV modules. Eventually, the perovskite PV modules successfully passed the stability tests in the TÜV Nord lab in December 2019.

Miss Tingting Xu, the Senior VP Renewables, TÜV Nord, awarded the environmental stability test report of perovskite PV modules to Dr. Jizhong Yao, the CEO of Microquanta.

The stability tests were carried out by TÜV Nord according to the IEC standards. It is a very important prerequisite for market entry of thin-film photovoltaic modules . There are four essential tests performed for perovskite modules, including:

·  Damp heat test: Modules are placed in an environmental chamber at 85 °C and relative humidity of 85% for 1000 hours;

·  Thermal cycling test: It cycles modules through two set temperature extremes, between 40 °C and 85 °C ;

·  UV preconditioning test: Modules are placed under 60°C and high-intensity UV light with a total continuous UV irradiation of 15 kWh per square meter;

·  Light soaking: Modules receive a continuous standard solar irradiation of 86 kWh per square meter.

The tests above simulate the impacts of water, oxygen, light, and heat to the PV modules in outdoor conditions, and evaluate their long-term stability and reliability. The perovskite PV modules fabricated by Microquanta have been through these strict tests, and the perovskite material and fabrication processes are proved to be satisfied with the application scenarios. The success of passing the stability tests means perovskite, a new photovoltaic technology, has crossed the "valley of death" of emerging technologies and demonstrates a significant leap in its development.

Miss Tingting Xu, the Senior VP of Renewables in TÜV Nord and the President of Global PV Cluster, stated that the first success of perovskite PV module passing the environmental reliability tests for commercial photovoltaic modules indicates that the perovskite PV technology has officially stepped out of laboratories and stepped in the market, marking the start of its new journey.

It was also announced that Microquanta and TÜV Nord will continue collaborating in perovskite-related fields to jointly promote the commercialization process of perovskite PV technology.
