1. 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.

3.4 General Hazards
Before installing or operating the UV Ozone Cleaner, there are several health and safety
precautions which must be followed and executed to ensure safe installation and operation.
WARNING: Improper handling when operating or servicing this equipment can result in serious
injury. Read this manual before operating or servicing this equipment.
I. DANGER: DO NOT use the UV Ozone Cleaner in the presence of an explosive
atmosphere.
II. WARNING: To avoid electrical shock or injury, do not remove tray or try to access
any internal parts. Servicing should only be carried out by a trained professional.
Before servicing, disconnect the power cord and wait 10 minutes (high voltage
may persist in capacitors for some time after removal of power).
III. CAUTION: The UV Ozone Cleaner uses a ground-type power plug, which must be
connected to a earthed outlet to prevent electrical shock. The UV Ozone Cleaning
unit will be supplied with an earthed plug appropriate for the country of
purchase.

9
IV. The UV lamp is a mercury vapour lamp. The user may be exposed to mercury if
the lamp glass breaks. If this happens, please abide by the following rules to
minimise exposure:
•Ensure the power is disconnected to avoid the risk of electrocution.
•Store the container and UV Ozone Cleaner in a fume hood and leave the
room under ventilation for at least 15 minutes.
•Using cut-resistant gloves, collect any stray pieces of glass in a sealed
container. Dispose of the glass at a suitable collection point.
V. The UV Ozone Cleaner has a high voltage source. Do not attempt to open the
unit.
3.5 Power Cord Safety
I. Emergency power disconnect options: Use the power cord as a disconnecting
method and remove it from the power source. To facilitate disconnect, make
sure the power outlet for this cord is readily accessible to the operator.
II. Only use the power cord supplied with the UV Ozone Cleaner. Using an
unearthed plug may result in serious injury or death.
3.6 Servicing
If servicing is required, please return the unit to Ossila Ltd The warranty will be invalidated if:
•Modification or service has taken place by anyone other than an Ossila engineer.
•The Unit has been subjected to chemical damage through improper use.
•The Unit has been operated outside the usage parameters stated in the user
documentation associated with the Unit.
•The Unit has been rendered inoperable through accident, misuse, contamination,
improper maintenance, modification, or other external causes.
3.7 Health and Safety –Installation
I. High-intensity, mercury vapour lamps can generate extreme heat and
temperatures. Furthermore, ozone is a powerful oxidising agent and can react
explosively with combustible materials. Keep flammable materials a minimum
of three feet away from operating equipment.

10
II. The UV Ozone Cleaner is intended for operation inside a fully functioning fume
hood or fume cupboard only. There is no ozone filtration system incorporated
into the UV Ozone Cleaner.
3.8 Health and Safety –Operation
I. UV radiation can cause severe burns to the eyes and skin. An integrated safety
interlock prevents the lamp from being powered on whilst the tray is open. As a
precaution, never look directly into the sample chamber when the UV ozone
cleaner unit is powered on.
II. Ozone is a highly reactive substance and can cause adverse health effects at
the sites of initial contact: The respiratory tract, lungs —and at higher
concentrations, the eyes. The principal health effects are caused by irritation or
damage to the small airways of the lungs, and symptoms include coughing and
a feeling of tightness in the chest. Uncontrolled exposure to high levels of ozone
could lead to more severe health effects.
III. When operating the UV Ozone Cleaner, air flow in and around the unit must
remain unobstructed to prevent the unit from overheating. If the temperature
inside the sample chamber reaches above 60 °C, the unit will flash a high
temperature warning and automatically switch off the lamps to prevent
overheating. Allow the system to cool down to room temperature before
resuming use.
IV. IMPORTANT NOTE: Excessive cooling will diminish the lamp’s operating voltage
and effectiveness, whereas Inadequate cooling may cause damage to system
components.
V. The UV Ozone Cleaner has a high voltage source. Do not attempt to open the
unit.
3.9 Health and Safety –Servicing
I. Service or installation work that includes integrating electrical components
should only be performed by an Ossila engineer. Never alter the wiring of any
purchased equipment. If changes are made, such alterations may damage the
equipment, cause injury, or even death. At the very least, such alterations will
void your warranty.

11
II. If the fuses located in the fuse drawer at the back of the unit need changing, the
unit must be placed in a safe mode by switching the unit off and disconnecting
the power cord from the power socket.
4. Unpacking
4.1 Packing List
The standard items included with the UV Ozone Cleaner are:

4.2 Damage Inspection
Examine the components for evidence of shipping damage. If damage has occurred, please
contact Ossila directly for further action. The UV lamp is a mercury vapour lamp and the user
may be exposed to mercury only if the glass of the lamp is cracked or broken. If this happens,
please contact Ossila after abiding by these rules to minimise exposure:
1. Ensure the power is disconnected to avoid the risk of electrocution.
2. Store the container and UV Ozone Cleaner in a fume hood and leave the
room under ventilation for at least 15 minutes.
