3rd Generation PV - Low Cost Dye Solar Cells
Overview
• 3GSolar is a global leader in the development of
Dye Solar Cells (“DSC”)
• Developed the world’s largest DSC at 5.4%, with
small research cells exhibiting up to 8.8%
• Working with exclusive Förster Resonance Energy
Transfer (“FRET”) technology, leveraging the power
of Quantum Dots to achieve 14% module efficiency
• Ultra low cost (unit and plant) and simple to
manufacture locally
• 13 patents and applications protect 3GSolar’s
industry leading innovations in design and scale-up

Zaban from Bar Ilan University and Dr. Dan Oron from the Weizmann Institute
• 3GSolar is backed by Solar Partnership, a fund advised by London based
Smedvig Capital and part of the $1.3Billion Smedvig Group
• In June 2011 Israel’s largest electricity supplier, the Israel Electric Company
made a strategic investment in 3GSolar
• Setting up collaboration with Prof. C. Berlinguette (Univ. Calgary) on dyes

Large, rapidly growing market
It is estimated that in
2009 about 7 GW of PV
solar capacity was
installed at a cost of
approximately $39 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

Simple to manufacture low cost cells
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
DSC Design
– Operators can be lower skilled
• 3GSolar will have a unit cost of $0.35/Wp

Superior product characteristics
versus competitors
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

FRET effect significantly boosts efficiency
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

3GSolar aims to reach module
efficiencies of 10% by 2014 and
14% by 2019

Work from lab of
Prof. A. Zaban, BIU
• 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 conversion

Conclusions
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
