Paul Davies has been exploring the esoteric nature of physics in his popular science books since the 1970s. The Arizona State University physicist talks to me about his latest book What’s Eating the Universe and Other Cosmic Questions and also gives some top tips for aspiring science writers.
Tandem solar cells show great promise for boosting the efficiency of solar energy systems. Physics World’s Margaret Harris speaks with Laura Miranda Pérez and Chris Case of UK-based Oxford PV, who explain why combining traditional silicon solar-cell technology with newer perovskite-based devices delivers a significant increase in performance.
- Margaret Harris has written an extensive blog about tandem solar cells that explains why the combination of silicon and perovskite technologies offers a way of meeting future targets for boosting global photovoltaic generating capacity.
- Paul Davies will be debating the fluid nature of physical laws at the How the Light Gets In festival in London later this month.
