Traditional photoelectric detection target systems have the property of unclear target imaging at different detection distances, which leads to their low detection sensitivity. Furthermore, their use ...

A method is presented to accurately and rapidly measure the spot central position of a Gaussian pulsed laser, especially for an ultra-short pulsed laser. The measurement system consists of a ...

We demonstrate an InP heterojunction solar cell employing an ultrathin layer (∼10 nm) of amorphous TiO2 deposited at 120 °C by atomic layer deposition as the transparent electron-selective contact.

Solar cells based on metal halide perovskites often show excellent efficiency but poor stability. This degradation of perovskite devices has been associated with the migration of mobile ions. MAPbBr3 ...
