Microquanta perovskite PV modules pass the IEC test of stability and reliability first time in the world. Perovskite PV technology crosses the "valley of death" of emerging technologies.
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
· 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
· 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
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.
