The impact of climate-based PV panel degradation rates on inverters

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.

Gallium arsenide solar cell achieves 23.1% efficiency via electrochemical porosification

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.

Solar in uncommon spaces

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.

Solar for trekking

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.

European consortium bid to bring 25.4%-efficient heterojunction-IBC solar cell into mass production

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.

IEA explores paths to PV and wind integration

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.

Imec hits 23.9% efficiency with tandem perovskite/silicon mini-module

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.

Sungevity enters partnership with leading Belgian solar firm

The U.S. distributed solar installer has partnered with Belgium’s Electrabel to begin installing rooftop solar panels across the country.
