Microquanta demonstrates high stability beyond IEC standards
From: Date:2020-08-11

Microquanta Semiconductor (“Microquanta” or “the company”)  announced its recent development in improving the stability of perovskite solar modules after it passed IEC stability tests in 2019 for the first time in the world. The 20cm2 perovskite module passed the 3000 hours damp heat test (3 times IEC standards) without degradation of efficiency. It also showed a degradation of less than 2% after a 100kWh UV preconditioning test (6.5 times IEC standards). These results of rigorous and demanding tests demonstrate the market readiness of perovskite technology from Microquanta and a product lifetime of over 25 years.

Perovskite solar materials are sensitive to light, heat, moisture ,and oxygen in real-world conditions. The perovskite solar cell itself will show irreversible degradation rapidly when it is exposed. In addition, the defects from production processes also contribute to the degradation, which makes the lifetime shorter than traditional solar cells. As a result, improvements of processes and stability are the major challenges in the commercialization of perovskite solar technology.


Microquanta optimise the composition of perovskite materials to increase its resistance to the tough environment. The company also make a great effort in encapsulation processes to better protect the perovskite materials.

Development Milestones

  • Perovskite mini modulus from Microquanta has been breaking world record efficiency in the last 4 years from 12.1% to 18.04%. The results were cited in the "Solar Cell Efficiency Table" from Prof. Martin Green and a group of scholars.

  • The large module with an efficiency of 14.30% was recorded in "Champion Photovoltaic Module Efficiency Chart" from NREL and "2019 Chinese Solar Cell Efficiency Chart" from China Photovoltaic Society (CPVS).

  • In December 2019, the perovskite modules from Microquanta passed IEC stability tests as the world's first, with degradation less than 5% in all damp-heat, temperature cycling, and UV stress tests.
