Figure High-Throughput Optical Simulations for color tailoring color filers

SIMULATION RESULT

ATEC employs high-throughput optical models to analyze thin film structures and help our clients find customizable optical-electrical thin films with the simplest structure.

Our optimized optical model is 1000 times faster than ordinary models. A standard home laptop with an Intel(R) Core(TM) i5-4210M CPU screen structures at a rate of 3000 structures per second. This rapid screening ability accelerates the prototyping process for thin film structures.

The figure on the left shows the simulation results used to find an optimal structure balancing the photonic crystal's energy conversion efficiency and aesthetic (transmittance) in semitransparent photovoltaic cells and tailoring color filters.

EXPERIMENTAL VERIFICATION

Key Features

  • Accuracy and Reliability results with experiments validation.

  • Narrow peak reflection

Specification

  • Number of layers: 11, 11, 15

  • Material : TiO2, SiO2

  • Reflectance (R, G, B): 60+, 80+, 99

The coating on the glass reflects color against a black background, mimicking an outdoor scene due to the transparent coating and the background's absorption of transmitted light.

COLOR TAILORING CAPACITY

The capability to tailor the reflection of colors encompasses a domain enclosed by the RGB (Red, Green, Blue) color reflection triangle within the color spaces. Factors constraining this domain include the intrinsic properties of the materials composition utilized and the number of layers applied in the filter construction.

In theory, more material choices and layers enlarge the domain areas and color tailoring capacity. With optical models, the fast screening models allow clients to explore whether the color reflection is feasible under clients' specifications.
