First Solar unit achieves world record CIGS solar efficiency of 23.64%

The new solar cell achieved a maximum power conversion efficiency of 23.75% and a certified efficiency of 23.64%, thus beating the previous world record of 23.35% achieved in 2019 by Japan’s Solar Frontier. The result was confirmed by the Fraunhofer ISE.

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.

Fraunhofer ISE, Oxford PV produce 25%-efficient perovskite-silicon tandem PV module

Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) announced today that it had produced at 421 W perovskite-silicon tandem glass-glass module measures 1.68 m2.

Meyer Burger to cease PV module production in Germany

Meyer Burger, a Switzerland-based heterojunction cell and panel manufacturer, says it will stop making PV modules in Germany, but it will continue to produce solar cells in the country to support its panel production operations in the United States.

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.

Enphase stock slides on weakened demand, significantly lowered Q4 guidance

U.S. revenues dropped 16% from the previous quarter while European sales fell 34%.

3Sun to offer Oklahoma-built modules by 2025, perovskites possible by 2027

3Sun, once limited to Enel projects, has plans for up to 9 GW of global module manufacturing capacity split between the Old and New World locations – with the potential of perovskite modules being available in 2027.

Creating a new tech standard for solar panels

Increasing solar generation efficiency is paramount as land availability decreases and costs rise. 3SUN’s bifacial hetero-junction CORE-H solar cells elevate energy production beyond the limits of PERC, PERT or TOPCon to set new expectations for efficiency in the solar industry.


Solar-powered sensors for wildfire detection

An AI-powered sensor was developed by Dryad Networks to detect wildfires and alert first responders.

Multi-generation photovoltaic leaf to produce electricity, thermal energy, water

A UK research team has developed a photovoltaic leaf concept that can produce electricity, water and thermal energy in a single device. The system, inspired by a leaf, is based on a biomimetic transpiration (BT) layer that cools down the embedded PV unit and utilizes excess heat from the cell to produce water and heat energy.
