1. Overview
The UV Ozone Cleaner is part of of the Institute of Physics award-winning Solar Cell Prototyping Platform*.
It provides a simple, inexpensive, and ecient 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 grounded outlet to prevent electrical shock. The UV Ozone Cleaning
unit will be supplied with an earthed plug appropriate for the country of purchase.
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
3.7 Health and Safety – Installation
3.8 Health and Safety – Operation
3.6 Servicing
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 (and transformer if using 110 V mains supply) supplied
with the UV Ozone Cleaner. Using an unearthed plug may result in serious injury or
death.
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 ammable materials a minimum of three feet away
from operating equipment.
II. The UV Ozone Cleaner is intended for operation inside a fully-functioning fume hood
or fume cupboard only. There is no ozone ltration system incorporated into the UV
Ozone Cleaner.
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 eects at the
sites of initial contact: The respiratory tract, lungs — and at higher concentrations,
the eyes. The principal health eects 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 eects.
If servicing is required, please return the unit to Ossila Ltd. Any other action will void the warranty.

11
3.9 Health and Safety – Servicing
4.1 Packing List
III. When operating the UV Ozone Cleaner, air ow in and around the unit must remain
unobstructed to prevent the unit from overheating. If the temperature inside the
sample chamber reaches above 65 °C, the unit will automatically switch o 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 eectiveness, 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.
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.
The standard items included with the UV Ozone Cleaner are:
• UV Ozone Cleaner unit
• Power cord set (specic for country of operation)
• User manual
4. Unpacking
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.
3. Using cut-resistant gloves, collect any stray pieces of glass in a sealed container. Dispose of the glass at a
suitable collection point.
