3. 3GSolar Cells & Technology
Leading Developer of Printed Dye Solar Cells (DSC)
LARGE GLASS POWER MODULES FOR
BUILDING INTEGRATED PHOTOVOLTAICS
SMALL GLASS & PLASTIC CELLS FOR
ENERGY HARVESTING (INDOOR & OUT)
DSC Technology
Light striking dye excites electrons
which are collected by titania to
become electric current
DSC is printed photovoltaics
3GSolar proprietary 2014 3
4. Small plastic and glass cells for energy harvesting
Eliminate batteries in low power consumer electronics, security
cameras, wireless devices, healthcare devices, etc.
Very superior indoors compared to other PV, especially silicon

8. Security Cameras and Alarm Detectors
• Monitor property from outdoor intrusion, unusual
movements, or child surveillance indoor.
• Can be installed outdoor, indoor, in offices and factories.
• No wires. Never replace or recharge batteries.
3GSolar proprietary 2014 8
3GSOLAR allows operation with indoor fluorescent light
and outdoor in poor light conditions (shade, clouds, etc.)

3GSolar offers transparent solar cells that are placed
on top of displays and allow indefinite operation
10. Agriculture - Livestock monitoring
• The farm industry has an annual turnover of hundreds of billions
• Neck and foot sensors identify, track and monitor animals, transmitting
physiological factors such as body temperature and heart rate.
