Solution-processed lead–tin binary perovskite photodetectors that have an external quantum efficiency of 85% at 850 nm, dark current below 10–8 A cm–2 and response time faster than 100 ps can be used in light detection and ranging applications, resolving sub-millimetre distances with a typical 50 µm standard deviation.
