Lead bromide perovskites have a larger band gap and are significantly more stable than their iodine counterparts, offering the perspective for higher voltage, tandem photovoltaics exceeding the Shockley–Queisser limit, and shorter time to deployment of photovoltaics. However, their efficiencies stil...
