Chinese perovskite module maker Microquanta has claimed a world record 20.2% conversion efficiency on a 20cm2, ‘third generation' solar cell.
The Hangzhou-based manufacturer, which has broken five previous records, announced the achievement on Friday and said the result had been confirmed by government entity the China Institute of Metrology.
Microquanta has focused on perovskite solar since its foundation in 2015 and, in October 2019, achieved a record 14.24% conversion efficiency on a large-area (200x800cm2) perovskite solar module. Two months later, the company's perovskite module became the first one to pass the IEC stability test. In July last year, Microquanta achieved a new record of 18.04% efficiency on a small-size module. In January, the company made another breakthrough in perovskite stability when its products passed three environmental aging tests: the 1,000hr light aging exam; 3,000hr hygrothermal aging test; and the 100 kWh ultraviolet aging test, all specified by IEC standard 61215:2016.
