New research from Belgium shows the importance of assessing inverter reliability by including climate-based PV panel degradation rates. The scientists found that, especially in hot and arid climates, PV inverters should be designed with parameters above the standard value.
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.
With land use concerns on the rise, large-scale solar projects increasingly are being sited on everything from landfills to water reservoirs. Here’s an overview of the state of the art.
Belgian start-up Sunslice has developed small, portable, high-performance solar panels that can be applied to backpacks and be used as rechargers for smartphones and watches.
The EU-funded Nextbase project aims to manufacture heterojunction, interdigitated back-contact solar modules for less than €0.275/W. Solar panels featuring the Nextbase cell tech are expected to have a conversion efficiency of 23.2%, according to the European Commission.
The International Energy Agency has released a manual for policy makers on the issues involved in the large scale integration of solar and wind power into power grids.
Belgian research institute Imec has achieved a conversion efficiency of 23.9% on a perovskite/silicon tandem module measuring 4 square centimeters. This efficiency level, according to Imec, represents the first time such a stacked configuration has outperformed a standalone silicon solar cell.
The U.S. distributed solar installer has partnered with Belgium’s Electrabel to begin installing rooftop solar panels across the country.
