“DSC modules yearly generated 10–20% more electricity than conventional crystalline-Si modules of the same rated output power.” Aisin Seiki/Toyota

Gain for DSC even higher under non-optimum angle of incidence (building façades)

Dyesol data

DSC c-Si

• Maximum power point voltage Vmpp of Dye Solar Cells depends much less on panel temperature compared to polycrystalline or single crystal silicon SureVoltTM

• Maximum power Pmpp of DSCs drops much less with temperature compared to Si

E. Radziemska, Renewable Energy, 28 (2003) 1.


Dyesol data

Relatively small influence of temperature on DSC performance, particularly below 60oC

no temperature compensation for DSC LCOE calculations (in a first approximation)


Sources: Meteonorm 6.0 + SAM (Solar Advisor Model NREL) Efficiency drop in summer months due to higher panel

temperatures

Efficiency drop ~mid April to August due to high per-centage of diffuse radiation and lower overall light levels


• DSC effective performance per m2 approaches Si performance on façades (20 years panel life to 80%)

• Si LCOE rises steeply with less ideal panel orientation

• DSC LCOE is almost independent of façade exposure East through West


• Silicon PV looses significant power and thus efficiency under elevated temperatures, i.e. under operating conditions

• DSC performance depends much less on temperature

• Silicon PV performs poorly under lower light conditions (because it is based on minority carrier transport)

• DSC performance (efficiency) improves with decreasing light levels and peaks around 0.2-0.3 sun, i.e. at average operating conditions (based on majority carrier transport)

• It is unlikely that silicon PV will drop significantly below 2$/Wp at the wholesale level

• DSC has the potential to reach wholesale prices of 1$/Wp and lower


• Architectural applications: relatively high $/m2 acceptable, competition with marble

• Generation at the site of consumption, i.e. at the

consumer retail electricity price, in buildings

• No solar farms, i.e. no competition at the generator electricity price

• Multifunctional DSC PV panels:

Electrical power generation

Heat insulation

Noise insulation

Light moderation/filtering


• Architectural appeal

• Colouration

• Transparency

• Coated Steel market - over 1 billion m2, growing at 7-8% pa

• Partnered with Corus (5th largest, Tata) plus interest from other steel companies to license from Dyesol/CORUS

• Potential for solar coated steel cladding 20% i.e. over 200 million m2 pa

• significant added value for Dyesol (materials, ~70$/m2)

• Addressable market ~$15 billion pa

Typical Coil Coating line

Corus Colourcoat – 100 million m2 pa Vast Colourcoat Roof


World Flat glass market

•2007 5.2 billion m2

•2010 5.2% growth per year

= 6.1 billion m2

DSC Technology - Addressing both markets

Dyesol Materials - At $50 - $75/m2 added value



• Despite DSC efficiencies still being 2x lower compared to silicon, electricity yearly produced by the two technologies become similar in façade orientation, particularly off-South (for the Northern hemisphere)

• With the exception of tracker-mounted PV, DSC provides, for the same $/Wp basis, lower LCOE than silicon PV

• Performance of façade-mounted DSC (in Cairo) hardly depends on façade orientation between SE to SW

• Even at 5% DSC panel efficiency and 2$/Wp, panel LCOE of less than 10 cts/kWh can be achieved with DSC, in most façade orientations
