Overview
The UV Ozone Cleaner is part of the Institute of Physics award-winning Solar Cell
Prototyping Platform*. It provides a simple, inexpensive, and efficient method of
obtaining ultra-clean surfaces free of organic contaminants. The UV Ozone Cleaner
can clean a wide range of substrates, such as quartz, silicon, gold, nickel, aluminium,
gallium arsenide, alumina, and glass slides.
The UV ozone cleaning process can produce an atomically clean surface in only a few
minutes. However, the substrate surface must be nominally clean beforehand. The
cleaning rate of UV ozone using atmospheric oxygen at ambient conditions depends
on the nature of the contaminant molecules, but is typically of the order of 0.1 - 1.0
Å/s. The exact exposure times and methods required to remove various contaminants
will vary and should be determined empirically.
The Ossila Solar Cell Prototyping Platform is a complementary collection of substrates,
materials, and equipment as part of a high-performance standard photovoltaic
reference architecture. This platform enables researchers to produce high-quality,
fully functional solar cells which can be used as a reliable baseline.
