Abstract:
All-perovskite tandem cells are attractive candidates for next-generation photovoltaic technology as they hold the potential to combine high-efficiency with low weight and reduced energy-payback times. Now, researchers show that such tandem cells can be engineering to be bifacial, allowing them to utilize stray light reflected off the surrounding environment, resulting in a 17% boost in the power output.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
