UV+IR
PV cell
• Allows >80% of natural light through while blocking >90%
of solar infrared (NIR) and thermal (FIR) energy
Clear, energy efficient glass that harvests solar
power & has excellent solar & thermal properties
The TechnologyThe Technology
of solar infrared (NIR) and thermal (FIR) energy
• Harvests solar (NIR) energy and converts it to electricity
• Up to 40% saving in cooling and lighting costs
Reduces building capital and running costs
• Visible light is transmitted largely unaltered
• IR and UV radiations are deflected to the edges
for collection by PV cells (> 35 W/m2)

TropiglasTropiglas is based on Micro is based on Micro
& & NanoNano TechnologyTechnology
Micro- & Nano- particles
interact with visible light,
and convert Ultra Violet
radiation to longer
wavelengths and scatters wavelengths and scatters
Infrared light to the edges
of glass for collection by
PhotoVoltaic cells,
therefore producing
electricity, reducing heat
and blocking damaging UV
and InfraRed rays.

Estimated Tropiglas market share*
• Efficient ‘harvesting’ of IR energy
• Superior natural light transmission
• Vertical placement - conserves space
• Future Goal: Reach net zero buildings
using Tropiglas Advanced Glazing
System and Daylighting featuring
COMPETITIVE ADVANTAGESCOMPETITIVE ADVANTAGES
System and Daylighting featuring
excellent thermal properties, solar
control & power generation
• Tropiglas E-Power is the only
uncompromised, totally clear BIPV
glazing product that not only
generates power but also reduces
power demand from lighting
(ultraclear), heating (insulating) and
cooling (has a low solar heat gain)
Tropiglas E-Power:
• BIPV glazing product
• >75% transparency (ultraclear)
• >90% IR blocking
• > 35 W/m2 power (power generating)
• >50 W/m2 possible through R&D
• U-factor < 1.8 W/(m2 °K) (insulating)
• SHGC < 0.41

**Experimental value by CIS cell
• Normalized scattering factor (75%) is considered.• Visible ray(400-700 nm) transmittance range is 30%-70%.• Small increase of power generation with transmittance decrease• Much more increase of power generation with cell efficiency increase

of energy use
Average office power consumption: 1200/1900= 0.6 kWh/m2/dayTropiglas power generation: 36W/m2 x 6h/day = 0.216 kWh/m2/dayFor an office of 3.5m x 6m area and ceiling height of 3m the average required power consumption is: 0.6x3.5x6=12.6 kWh/dayTropiglas E-Power windows:1. Generate: 0.216x3x6 = 3.9 kWh/day ~ 31% of office consumption
2. Allow ~75% of visible light to transmit ⇒Substantial savings on lighting,3. Stop 90% of solar IR & 95% of thermal IR ⇒ Substantial cooling & heating savings
