Isomer passivation for a 21.4% efficient perovskite module
An international team of scientists trialled a new approach to passivating defects in perovskite solar cells. Using a tailored arrangement of atoms, the team was able to overcome challenges related to the formation of a two-dimensional perovskite layer on top of the active cell material, and reach 21.4% conversion efficiency for a 26cm² active area, which they claim as a record for a perovskite device of this size.
Shipping problems for First Solar but production line expansion is under way

Chinese PV Industry Brief: Two major deals for PV production equipment
JSG has sold several ingot furnaces to Shuangliang Eco-Energy and Jinchen Machinery will provide Yingli with production equipment totaling 3.5 GW.
Gallium arsenide nanowire solar cell with 7.7% efficiency
Norwegian scientists have developed a gallium arsenide (GaAs) nanowire solar cell that can be used as a top cell in a dual tandem cell with a bottom silicon cell. The device is claimed to be the most efficient single-junction GaAs nanowire solar cell grown on a silicon substrate so far.
New laser-cutting system for half-cut, shingled PV cells
German manufacturer 3-D Micromac said it has developed a new machine that can produce more than 6,000 wafers per hour. It is suitable for solar cells with temperature-sensitive coatings, or depositions such as heterojunction devices.
End-of-life management of solar PV waste in India
A new study proposes an ‘extended producer responsibility’ regulatory framework for end-of-life solar PV management in India.
How PV performs close to radio, TV antennas
Researchers in Kenya have analyzed the performance of an off-grid PV system located near an isotropic antenna as an emitting source.
Lithuanian module maker says European and US clients moving away from Chinese supply chain
Vilnius-headquartered Solitek is preparing to ramp its output next year on the back of rising orders in Scandinavia, and says its new partnership with New York-based Convalt Energy will reduce its dependence on Asian semiconductors and solar cells.
Established thin film processing for 18%-efficient perovskite mini-modules
Scientists in Germany applied vapor-based deposition techniques and laser scribed interconnection – both well established processes in existing thin-film solar manufacturing – to fabricate perovskite mini modules. The group achieved a maximum efficiency of 18% for a device measuring 4cm². Relying on these processes, they say, could simplify processing and reduce losses associated with scaling up to commercial-sized devices.
