In addition, seeking for light trapping surfaces has been a great challenge for researchers and now the research on light trapping materials has attracted more and more people's attention because of the increasing importance of light trapping materials.
Moreover, this work sets up a strategy for the design and fabrication of super light trapping materials and may encourage people to look for more super light trapping architectures in nature.

The SiO2 negative replica was not only stable but also corrosion resistant due to the complex super light trapping architectures and inert SiO2 material, which made it a promising super light trapping surface for various fields such as photoelectrical devices, photo-induced sensors and solar cells.

In addition, silver nanoparticles can excite resonance effect of light trapping when pairing with dielectric materials, such as polymer.
Therefore, the light absorption of sample ALD is as high as 98%, which may result from synergistic band structure of the heterogeneous materials, the light trapping effect for the hierarchical architecture, and the smooth transition of refractive index from air (n = 1) through ZnO branches (n = 2.0) to Si backbones (n = 3.5).
The double-pass thin film assumes perfect antireflection at the front surface of the thin film and perfect reflection at the back surface, such that light passes through the material twice with no light trapping.
At the same time, the high aspect ratio of nanowires and micropillars enhances absorption through superior light trapping mechanism, allowing significantly thinner structures and thus reduced material cost.
The enhancement of photocurrent density with gold nanoparticles in our experiment was obvious, and we just provide a method to improve the light trapping in lower D/P ratios to save the GaAs material.
