Abstract
Advanced characterisation plays an important role for further improvements of the cost effectiveness ($/Wp) of solar cells. This paper presents an overview of advanced characterisation techniques that are presently being used for the analysis of silicon wafer solar cells, either in the laboratory or in the [...]
Atomic Layer Deposition (ALD), also known as atomic layer epitaxy (ALE), is an atomic-scale thin film preparation technology. It can deposit ultra-thin films with uniform thickness, controllable thickness and adjustable composition. With the development of nanotechnology and semiconductor microelectronics, the size requirements of devices [...]
