Professor Xu Xingquan, Professor of the Department of Electronic and Information Engineering of The Hong Kong Polytechnic University (PolyU), recently joined hands with Mainland scholars to jointly develop high-efficiency solar (000591) cells, which use the new perovskite/monocrystalline silicon tandem solar cell technology to achieve an energy conversion rate of 25.
5%, which is a significant increase
from 3.
8% in 2009.
The team estimates that this scientific achievement can reduce the cost of solar energy from the current HK$3.
9 per watt of silicon-based solar cells to HK$2.
