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
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.
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.
