“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)

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$/Wp at the wholesale level
• DSC has the potential to reach whole- sale prices of 1$/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

• 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
