This makes homes and businesses more energy-efficient and contributes to a greener, healthier atmosphere for all to enjoy. Saving money on cooling costs by keeping surfaces cooler is a benefit to consumers, but using IR reflective paint technology also helps to protect our environment by using less energy. Easier cooling of vehicles on warm daysĮxterior applications which can benefit from incorporating this technology include:Ĭhromaflo Technologies’ colorants for IR reflective paint and coatings protect substrates against excessive temperatures and UV radiation by reflecting the IR wavelengths and limiting ultraviolet radiation.Improved durability in industrial applications.Reduced energy costs in homes and commercial buildings.Some additional advantages of keeping exteriors cool include: This keeps exteriors cool and coatings long lasting. Our proven technology stems from a perfect blend of proper pigment selection, optimized milling and tight manufacturing cleanliness practices. This provides for superior solar reflectance for IR reflective paint and coatings formulations. Conversely, the higher the solar reflectance, the cooler an object will stay.Ĭhromaflo Technologies’ colorants for IR reflective paint and coatings work to maximize total solar reflectance. The more solar energy an object absorbs, the greater the heat build-up. High solar reflectance, in turn, lowers solar heat gain while high thermal emittance enhances thermal radiative cooling.

The other two structures have lower values of transmission, meaning that they are good candidates for low-efficiency solar cells. Using two layers of SiN x between the air and glass gives almost zero reflection at 600 nm, making this approach an outstanding candidate for solar cells with a maximum absorption of around 600 nm. An analysis is carried out using Maple 17, and the results show that using a sol-gel material between glass and air gives almost zero reflection for a wide range of wavelengths, meaning that this can be used as a perfect absorbent and can therefore be recommended for high-efficiency solar cells. A transfer-matrix method is used to solve for the total transmission and total reflection for all structures, and the effects of the film thicknesses and incidence angles are considered in each case. The four proposed solar cell structures are as follows: (i) a three-layer solar cell in which a sol-gel film is used to match the refractive index between the glass substrate and air cladding (ii) a four-layer solar cell in which a sol-gel film is used to match the refractive index between SiN x laid on top of a glass substrate and air cladding (iii) a four-layer structure in which a sol-gel film topped with air cladding is used as a match between the glass and SiN x and (iv) a four-layer solar cell in which two layers of SiN x are stacked between the glass and the air. In each model, the absorbent material is Borofloat glass and the antireflection coatings used are SiNx and sol-gel -based materials. For improving the performance of solar cells, this paper introduces four proposed structures for solar cells and examines their efficiencies for potential production with low cost and high efficiency.
Designing a solar cell that can harvest energy with a high level of efficiency is an important research topic.
