Titel
Fluid wrap around during wet chemical single side treatments
Abstract
Single sided etching is commonly used for processing solar cells. As with all single sided processes using wet etching solutions, fluid wrap around appears. This paper investigates this effect in two ways. Different experimental setups will be shown and described including results and theories concerning the fluid wrap around. It can be proven, that bursting bubbles caused by etching support the fluid wrap around as well as some additives and surface morphologies. Additionally, surface tension, surface energy and surface morphologies can be found as influencing factors. Further investigations for better understanding of the fluid wrap around will be described.
