Perovskite solar cell with 21% efficiency includes tech to prevent lead leaks

U.K. scientists have used mesoporous scaffolds based on hydroxyapatite nanoparticles – blended with titanium oxide nanoparticles – to create a mechanism that prevents lead leakage in perovskite solar cells. They claim the method captures lead ions in leaks, while also increasing cell efficiency.

Temperature and the case for bifacial

U.S. scientists have developed a model to predict the performance of bifacial PV at project level. Their results show that when improved temperature sensitivity is properly taken into account, the advantage of bifacial modules could be even larger than previously thought. And for upcoming module technologies like heterojunction in particular, it could mean bifacial is viable in even more parts of the globe.

Instant battery electrodes – just two minutes in the microwave

Scientists in the United States have used microwaves to convert ubiquitous plastic packaging material polyethylene terephthalate into a battery electrode component. The researchers say anodes based on the material could be suitable for both lithium-ion and sodium-ion devices.
