Visualization of Light-Impinging Geometry in Nonlinear Photocurrents of Vertical Optoelectronic Devices.

Summary: Imagine shining a flashlight on a solar panel. If the panel is flat on the ground, it is easy to measure the exact angle of the light. But what if the device is built in vertical layers? The math gets tricky! Scientists looked closely at how light hits these vertical devices, which act like tiny light sensors. They found that the angles of light act differently than expected when hitting a vertical structure. Because of this, the electrical currents created by the light change, too. Understanding this new light geometry helps us build better, flexible electronics for the future!
