In microelectromechanical system manufacturing and especially in the photovoltaic industry, wet-chemical baths are used for surface structuring, conditioning, and cleaning. Ozone-based wet-chemical cleaning processes show, in addition to the cleaning

Silicon Heterojunction (SHJ) solar cells represent a key technology to approach very high conversion efficiencies close to the theoretical limit of silicon solar cells. The main advantages of SHJ solar cells are a lean production chain with low tempe

The performance of PERC solar cells benefits from a smooth rear surface due to a reduced surface recombination and increased light trapping. State of the art surface roughness is defined solely by the polishing silicon removal. However the initial te
The measurement of bulk lifetime values of as-cut wafers is a problematic issue. In this work, a MDPLinescan tool was directly integrated in the last stage of an inline wet chemistry tool. It is shown that running as-cut wafers through a bath of 5% H

To enable a concentration control in the acidic texturing process we have closed the feedback loop from analytical data to the dosing mechanism of the used process tool. In order to analyze the process bath we used near-infrared spectroscopy in an on
