An international research group has utilized through-substrate-vias to create 3D interconnections in III-V solar cells with a triple-junction architecture. The novel cell design was found to have a low shading factor of below 3% and a 6-fold increase in wafer area use compared to cells based on 2D interconnects.
An international research group has utilized a new porosification technique to build gallium arsenide (GaAs) solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost thanks to the reuse of germanium.
First Solar and its cadmium telluride (CdTe) technology dominate thin-film solar in the mainstream market. Valerie Thompson looks at the US-based business and the future of thin-film PV technology.
As the world’s solar manufacturers continue to ramp up production at an eye-watering speed, a cell connection technique up to 10 times faster than the industry standard holds rich promise, according to Keven Tremblay, from Canadian laser process specialist Laserax.
FNB Gas has unveiled plans for a hydrogen core network in Germany, while Tree Energy Solutions has started working on an electrolyzer and 1 GW of renewable energy assets in Canada.
The Japanese government has confirmed to pv magazine that it is launching a new support scheme for hydrogen in aviation, while Japanese investors continue to actively pursue participation in a green ammonia project in South Africa.
