It is estimated that in 2009 about 7 GW of PV solar capacity was installed at a cost of approximately $39 Billion

In 2010 that number was $82 Billion

• 3GSolar is targeting the largest segments of the market – on and off grid power market

• The key requirement within these market segments is the cost of the panel for a given amount of electricity created on a given day – 3GSolar DSC is well placed with its ultra low cost offering 5

3GSolar designs high efficiency DSC’s using simple low cost manufacturing processes

•Ultra low cost, readily available materials with low toxicity

•Simple low cost manufacturing techniques enable local manufacture

– Simple screen printing approach keeps capital cost low – no vacuum ($7M for a 20 MW plant)

– Low Labor Costs – automated screen printing based production reduces the number of operators required to operate a plant

– Operators can be lower skilled

•3GSolar will have a unit cost of $0.35/Wp

Simple to manufacture low cost cells

DSC Design

3GSolar designs high efficiency DSC using simple low cost manufacturing processes

•Converts more light into energy than silicon

– Effective in occluded light conditions – earlier and later times of the day, cloudy conditions, high latitude geographical locations

– Same efficiency more energy, 15% across a day in the example on the right, but up to 40% more energy in certain conditions

Superior product characteristics versus competitors

Förster Resonance Energy Transfer (FRET) is a key way to increase DSC efficiency: we will be adapting the Professors’ input into our large area cells

•FRET separates the light absorption process from the electron injection process

•3GSolar can therefore optimise the materials for these two functions separately

•Quantum Dots (“QDs”) can be used to broaden the spectrum of light absorbed by DSC dye

•A far greater proportion of the light spectrum can therefore be converted into electricity

FRET effect significantly boosts efficiency

3GSolar aims to reach module efficiencies of 10% by 2014 and

14% by 2019Photon flux of the AN 1.5 G spectrum at 1000 W m-2 (ASTM G173-03),

FRET

• Incident photon conversion spectra on three different electrode structures:– nc-TiO2/QD/a-TiO2

– nc-TiO2/a-TiO2/dye– nc-TiO2/QD/a-TiO2/dye

• Combining QDs and dyes in FRET process dramatically increases photon conversion over whole visible spectrum

• Shifting dye absorption to longer wavelengths will further increase conversion9

Dec 2011 Dec 2012 Dec 2013 Dec 2014 Dec 2015

Phase 1

Completion of current R&D (11% efficient small cell by

December 2012)

Phase 2

Construct and optimize 100 kWp pilot plant (10% efficient module

by end 2013)

Phase 3

Conclusions

11

3GSolar is a global leader in development of Dye Solar Cells (“DSC”)

The alignment of:

– Low plant capital costs

– Low cost of production

– High performance in ‘real’ light conditions

– Significant improvement in DSC module efficiency with FRET

Means that 3GSolar DSC will have a market leading position

A 3GSolar DSC in 2019 could cost less than half a silicon panel to produce the same energy across a day
