Solar & Energy
Multi-functional coatings that enhance solar panel output. ATO glazing for thermal management in buildings. Every coating designed for outdoor durability and long-term performance.
Solar panel multi-functional coatings
Four functions. One coating system. 6-8 month ROI.
Solar panels in the field lose significant output to reflection, soiling, and thermal effects. Kriya’s all-in-one multi-functional coating addresses all three loss mechanisms in a single application, delivering measurable kWh gains flash-testable on the production line.
Enhanced AR (underlayer)
up to +4%
Measurable via flash-test. LRI coating reduces Fresnel reflection at glass-air interface.
Anti-soiling
+10-15%, depending on circumstances and local climate
Self-cleaning surface reduces dust and dirt accumulation. Field-verified performance gain.
Anti-heat / hotspot prevention
performance increase depending on circumstances and local climate
Thermal management protects cells and maintains output in high-irradiance conditions.

10-year value per 400W panel
Economics that scale with feed-in tariff
China (auction pricing)
CNY 802
0.225 CNY/kWh. All-in-one coating value over 10 years at +356 kWh/year gain.
Europe (premium tariff)
CNY 1,926
2.4x China pricing. European feed-in tariffs make all-in-one coatings highly attractive.
USA (net metering)
CNY 5,614
Up to 7x China pricing. US residential net metering delivers strongest ROI for coating investment.
Based on 400W silicon panel, Shandong Province reference. CIGS thin-film panels show additional +3-5% light incoupling enhancement.
These figures represent a snapshot in time and are dependent on local feed-in tariffs among other factors.
ATO glazing for buildings
Solar heat control for architectural glass
The same ATO nanoparticle technology proven in automotive windshields applies to architectural glazing. Kriya ATO blocks near-infrared radiation while maintaining high visible light transmission, reducing HVAC load in commercial and residential buildings.

5G safe
100% RF transparent (oxide-based)
| Layer | Refractive index | Kriya material | Product |
|---|---|---|---|
| Exterior (air) | 1.00 | No | N/A |
| Outer glass pane | 1.52 | No | N/A |
| Kriya ATO solar heat control | Yes | ATO masterbatch | |
| PVB / laminate interlayer | 1.48 | No | N/A |
| Inner glass pane | 1.52 | No | N/A |

LRI for architectural light guiding
2.5-4.5x luminance improvement on glass
Kriya LRI coatings (RI 1.37) on glass have been validated by a European glass industry leader for enhanced light guiding in architectural and automotive applications. The coating survived furnace tempering at 630 deg C with no deterioration.
2.5-4.5x
Luminance improvement vs uncoated glass in light-guiding application
630 deg C
Survives furnace tempering (250s at peak + rapid cooling). No deterioration.
+3.9%
Transmission gain on glass (89.9% to 93.8% with thermal-curable LRI)
