The enhancement of photocurrent and power conversion efficiency (PCE) reveals strong wavelength dependence owing to the selective reflection of these CLC polymer films.
The results show that the reflection loss could be reduced owing to the lower reflectivity of this structure.
Meanwhile, owing to the intrinsic low-reflection property, average reflectance as low as 10% is accomplished.
However, more than 30% of the incident light is lost through Fresnel reflection owing to the large refractive index difference between air (nair = 1) and Si (nSi approximately 3.8), and therefore, antireflective structures are indispensible to improve the device performance.
However, this configuration suffered from problems related to correcting for specular reflections owing to the effects of polarization, and fiber optic bundle implementations of LOT have also proven problematic [ 22].
Research shows that the input light still can be propagated with high efficiency down to multimode optical area, and resemble index-guided modes owing to the combination of total internal reflection and distribution Bragg reflection.
In our previous study of Ag nanoparticles embedded in ordered array of anodic aluminum oxide (AgNP/AAO substrate) [21], scattering spectra-rather than transmission or reflection spectra owing to their optical inference-of such array with different interparticle gaps were acquired to reveal their electromagnetic resonance properties.
The performance shows that the TM modes can also be propagated with high efficiency, and resemble index-guided modes owing to the combination of total internal reflection (TIR) and distribution Bragg reflection.
In spite a significant increase in the domains reflectivity has been observed owing to the modification in the mentioned enhanced reflection, the texture of the domains remains equal.
It is well known that the XRD technique is limited for the crystallographic characterization of fine crystallites owing to extensive broadening of Bragg reflections and generally not very sensitive to transitions involving oxygen displacements.
Indeed, women's experiences of limited post-test counselling owing to few health workers is a reflection of the national and global human resource crisis affecting many sub-Saharan countries.
