Color plays an important role in human life: without it life would be dull and monochromatic. Printing color with distinct characteristics, like hue, brightness and saturation, and high resolution, are the main characteristic of image sensing devices. A flexible design of color filter is also desired for angle insensitivity and independence of direction of polarization of incident light. Furthermore, it is important that the designed filter be compatible with the image sensing devices in terms of technology and size. Therefore, color filter requires special care in its design, operation and integration. In this paper, we present a comprehensive review of nanostructured color filter designs described to date and evaluate them in terms of their performance.

“…Using metasurfaces as beam-formers [11,12], lenses [13], and absorbers [14,15] increase absorption of the thin-film solar cells. Directive nano-antennas integrated inside the solar cells could receive the visible light from the free space and improve the absorption [7,16,17]. The fractal structures trap sunlight at different wavelengths leading to near-unity absorption [18,19].…”

“…In recent years, nanostructures have been applied to thinfilm solar cells to trap sunlight and increase photo-current generation [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The nanostructures inside the solar cell increase the optical path length of photons leading to absorption enhancement.…”

“…Despite all these efforts, some drawbacks like plasmonic loss [7,13], dependency on polarization [11,12], and narrow bandwidth [11,17] cause failure in the realization of an efficient solar cell. Another important disadvantage of thin-film solar cells is a dependency on the sunlight angle of incidence, which needs mechanical rotation during the day and in different seasons of the year [7,13,[15][16][17].…”

In this paper, we proposed a new method to realize the rotational freedom of thin‐film solar cells. In this method, an array of reconfigurable nano‐patches fed by a plasmonic waveguide is integrated inside the solar cell to receive and trap light in the active layer. The reconfigurable nano‐antenna is designed to achieve beam steering by bias voltage in the direction of sunlight during the day using 4‐Dimethyl‐Amino‐N‐methyl‐4‐Stilbazolium Tosylate as an active electro‐optic material integrated into the plasmonic waveguide. The proposed solar cell is investigated using the finite‐difference frequency‐domain method and the drift‐diffusion equations of COMSOL Multiphysics software at different wavelengths of light and a wide range of angles of incidence for transverse magnetic (TM) and transverse electric (TE) polarizations. The numerical results show increase in the absorption in large wavelengths of sunlight for the thin‐film solar cell with nano‐antenna, resulting in a short circuit current enhancement of 1.48 and 1.45 for TE and TM polarisations, respectively. Also, another advantage of the proposed reconfigurable structure is maintaining the performance in different angles of incidence, which may open up a new opportunity in solar energy harvesting.

“…Also, the top surface can incorporate multilayer planar antireflection coatings (ARC) 18 , etc. Recently some advances have been reported 17,[19][20][21][22] for the use of nanoparticles (NPs) as elements included into the ARC, as well as integrated into the back contact, and even inside the active layer. When these NPs are metallic, the solar irradiance excites Localized Surface Plasmon Resonances (LSPR).…”

Nanostructured anti-reflection coatings (ARC) are used to reduce the reflectivity of the front surface of solar cells. Computational electromagnetism helps to evaluate the spectral reflectivity of of this type of ARC using several approaches. They typically require large computational resources both in time and hardware elements (memory allocation, speed of processors, etc.). Long computational times may jeopardize optimization processes based on the iterative evaluation of a given merit function that depends on several parameters. Then, simplified analytic methods can speed up this evaluation with moderate computational resources. In this contribution we adapt an Effective Index Model (EIM) to the case of the design of an ARC made with nanoparticles (NP) embedded in a medium at the front surface of a thin-film silicon solar cell. Our approach modifies the discrete dipole approximation method to adapt it to the geometric and material properties of the NPs. The results obtained from the analytic method are compared with those evaluated through a Finite Element Method (FEM) for several cases involving variations in the size and geometry of the NP arrangement, obtaining reflectances that differ less than 10$$\%$$ % for the worst case analyzed but bieng about 100 times faster than the FEM.
