Scientists recently made a breakthrough discovery in ultrafast carrier diffusion visualization. By using a new technique in combination with a high-sensitivity microscope, they were able to observe and record a process that was previously too fast to be seen. This process, known as ultrafast carrier diffusion, is the movement of electrons in a semiconductor material and takes place in a matter of femtoseconds (one femtosecond is one quadrillionth of a second). The breakthrough discovery means that researchers can now observe how quickly electrons move in a range of materials, including organic semiconductors. This could lead to the development of more efficient solar cells and faster electronic devices.
