CIGS solar panels for offshore PV
A Dutch consortium is testing a 20 kW pilot floating PV installation for offshore applications with CIGS solar modules developed by Swedish manufacturer Midsummer. The panels consist of 144 solar cells and measure 4 m X 1 m, with up to 485 W of capacity.
Green solvents for a 17%-efficient organic solar cell
Scientists in Sweden and China developed a solution-based process to produce organic solar cells, demonstrating efficiencies better than 17%. The process utilizes paraxylene as a solvent, which the researchers claim is less toxic and more stable than others used to reach high organic solar cell efficiencies, and with more work could be scaled up to produce large area devices.

The Hydrogen Stream: EU aims for €1.80/kg by 2030, BP announces green and blue hydrogen production in the UK
Also, Petroleum Development Oman wants to become the main player in the country’s plans to become a hydrogen hub and Emirates Global Aluminium says it wants to increase its hydrogen consumption.
Flexible 200 W solar module for boats, caravans
Offered by German provider Green Akku, the module is only 2mm thick and has a weight of between 1.45 and 3.63kg, depending on size. It can can be bent up to 50 degrees.
Coupling photovoltaics with linear generators
A 3.3 MW rooftop PV array and 480 kW of linear generators are currently being used to cover 100% of the electricity needs of a logistics facility in California. The hybrid energy system is relying on a linear generator technology provided by U.S. specialist Mainspring Energy that converts mechanical energy into electrical energy.
