Inverter undersizing not universally effective to reduce soiling losses

An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter under sizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.

IRENA says world needs 1.1 TW of renewables per year

The International Renewable Energy Agency (IRENA) released a new report on the sidelines of the Berlin Energy Transition Dialogue this week describing the actions needed so the world complies with targets set at the recent COP29 conference in the United Arab Emirates. IRENA President Francesco La Camera says renewables are the only energy sources with the speed and scale to achieve the ambitious targets set in Dubai.

Scientists identify new ‘promising’ absorber material for thin-film solar cells

Researchers in the United States have identified zintl-phosphide (BaCd2P2) as a new potential high efficiency absorber material for thin-film PV applications among 40,000 promising inorganic materials. The selected compound has a potential energy bandgap of 1.45 eV and a carrier lifetime of up to 30 ns.
