Transparent amorphous-silicon solar cell lets in more than 60% of visible light
Scientists in Spain have developed an amorphous-silicon solar cell that could be used in both transparent photovoltaics and tandem applications. The device reportedly achieves notable efficiency levels and may offer an alternative to transparent organic photovoltaics.
Spain’s grid operator warns of sudden voltage variations in the network
Red Eléctrica de España (REE) says sudden voltage variations in Spain’s grid are tied to renewable generation shifts, but there is no risk of blackout.
Standardized testing for indoor PV
Researchers at Simon Fraser University in Canada have proposed protocols for standardized testing to avoid skewed results. The validated recommendations cover procedures for key measurements and the use of the indoor PV reference cell method.
Cooling PV panels with stagnant water layer
Researchers have developed a stagnant water layer cooling concept and tested it using seawater, tap water, and desalinated water. The panel temperature decreased by up to 8.2 °C, while power output increased by approximately 28%.
Spain installs 7.2 GW of solar in 2024 amid rooftop slowdown
Spain added 7.2 GW of new solar capacity in 2024, bringing total installations to more than 40 GW, though rooftop deployment fell sharply, according to the national PV association.
