World Class Capabilities

3GSolar – Innovative Energy Products

3GSolar proprietary 2014 2

3GSolar Cells & TechnologyLeading 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 TechnologyLight striking dye excites electrons

which are collected by titania to

become electric current

DSC is printed photovoltaics


� 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

3GSolar eliminates the need to recharge or replace batteries


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 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

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.


3GSolar DSC provides more energy

than a battery and therefore can add

functionality to the livestock sensor

Computer Peripherals

• Operate computer peripherals from indoor fluorescent light

• Convenience of operation without ever charging or replacing batteries

• No more concern about responsible disposal of batteries.

• Many kinds of devices: keyboards, mice, webcams and more
