A brief history of perovskites
The word "perovskite" describes a naturally occurring mineral, but also a whole range of highly specialized synthetic compounds that have promising applications in electronics and photovoltaics. But what do they actually have in common? Who discovered them? And how are researchers using them to create innovative technology? This is the focus of the new issue of Empa Quarterly.

What is the battery of the future made of?
The Empa research group led by Maksym Kovalenko is researching innovative materials for the batteries of tomorrow. Whether it's fast-charging electric cars or low-cost stationary storage, there's a promising material or a novel manufacturing process for every application. What are the hallmarks of a good battery? Is it its capacity? How fast it charges? Or its price? The answer depends on where the battery is used, says Empa researcher Kostiantyn Kravchyk.

Battery-go-round
Empa and Kyburz Switzerland AG are looking for ways to recycle end-of-life lithium-ion batteries in an efficient and resource-saving way. A specially developed experimental facility breaks down the old batteries into their components so that materials can be recovered as clean as possible. Everyone is familiar with this phenomenon from their cell phone or laptop: Over time, the capacity of the battery decreases, so that you have to reach for the charger more and more often.

Photovoltaic systems under snow pressure
This week, the photovoltaic sector will gather in Munich for Intersolar Europe, the world's leading exhibition for the solar industry. Solar plants in the Alps have the potential to deliver high output. The SLF analyses the threat they face from alpine hazards and helps to protect solar facilities. Photovoltaic systems at high altitudes on mountainsides could be a successful model thanks to the high light intensity, sloped surfaces and a light efficiency exceeding that of the lowlands.
