Perovskite photovoltaics (PV) are poised at the brink of commercialization, yet stability remains the foremost hurdle to overcome for widespread adoption. While extensive research has addressed the degradation of perovskite PV through accelerated indoor testing, outdoor testing remains relatively underexplored and primarily focused on small cells rather than modules.

This gap underscores the urgent need to comprehensively study outdoor degradation processes. Understanding how perovskite PV modules perform under real-world environmental conditions is crucial for advancing toward commercial viability.

In our work published in ACS Energy Letters, we present a two-year outdoor evaluation of perovskite modules, shedding light on their degradation under real-world conditions. Our findings highlight a significant milestone in perovskite PV research, with the most robust module maintaining 78% of its initial performance after one year. Performance loss rates during the burn-in period were found to be about 7%–8% per month.

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of single cells, simultaneously. Detecting the location of hundreds or thousands of biomolecules—from lipids to metabolites to proteins—in their native environment allows researchers to better understand their functions and interactions. Unfortunately, scientists don’t have great tools to accomplish this task.

Now a multi-institutional research team has developed a tissue expansion method that enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations. Their paper is published in the journal Nature Methods.

Imaging methods, including most types of microscopy, provide a view of molecules inside cells. But they can track only a select handful of molecules at one time, and they can’t detect all types of biomolecules, including some lipids. Other methods, like regular mass spectrometry, can detect hundreds of molecules but don’t work on intact samples, so researchers can’t see how the biomolecules are oriented.

Researchers at Purdue University have developed an “ultra-white” paint that reflects 98 per cent of sunlight and deflects infrared heat, allowing buildings to cool below the surrounding air temperature.

The paint, which the university describes as the “whitest paint on record”, owes its cooling power to barium sulphate – a pigment derived from the mineral barite – and reflects up to 98.1% of sunlight.

Unlike the titanium dioxide used in traditional white paints, which absorbs UV light, the barium sulphate is also capable of deflecting infrared heat away from the surface to which it is applied.
