Surface engineering for an 18.6% efficient large-area inverted perovskite solar cell
Scientists in China worked with nickel-oxide as a charge transport layer in a perovskite solar cell, and were able to overcome several of the performance challenges associated with this material through careful surface engineering. Using this approach, the group fabricated an inverted perovskite solar cell measuring 156×156 mm that achieved 18.6% efficiency, along with ‘remarkable’ stability, according to its designers.

Chinese manufacturer Bslbatt has unveiled an upgraded version of its residential battery. The device has a storage capacity ranging from 5.12 to 12.8 kWh and is reportedly able to provide steady operation for up to 6,000 charge cycles.
Manz exits solar business
The German PV equipment manufacturer said it will discontinue all activities in the CIGS thin-film area after writing off €23.2 million due to a failed fab project in China.
Chinese PV Industry Brief: Polysilicon price remains flat
In other news, JinkoSolar is seeking to raise CNY 10 billion ($1.48 billion) to finance its capacity expansion plans and Trina Solar predicts strong profit growth for the first half of the year.
Graphene/silicon heterojunction solar cell with 18.8% efficiency
A Chinese-German research group developed the cell with an ink of graphene oxide (GO) mixed with Nafion that can be spin-coated on an n-type silicon wafer to form a high-quality passivating contact scheme. The GO:Nafion layer simultaneously creates a p–n junction with silicon and passivates the surface defects at the GO:silicon interface.
