China-based thin-film PV firm Hangzhou Microquanta Semiconductor has launched a mini-module with 16 per cent conversion efficiency for perovskite. This was certified by the Newport PV Lab in Montana, US. The tested mini-module has an aperture size of more than 16 square cm. The firm has upgraded from 15.2 per cent to 16 per cent efficiency within a span of three months. The progress was made primarily due to the focus on improving the deposition uniformity for large area thin-films.
