“…In the last years, the strong progress in photonic technologies has led to a growing interest in this field, opening the possibility of new applications, including renewable energies. Some examples of these new applications are energy-harvesting windows [18], luminescent solar concentrators [19], photonic color back reflector [20], solar energy trapping [21], filters to avoid thermal heating of the device [22,23], or beam splitters to combine different solar technologies [24].…”

“…A mechanism that has been proposed to prevent the increase in temperature is to use photonic crystals as selective filters of the solar spectrum on the solar cell [22,23]. The advantage of this beam splitter concept is that 1DPC acts as a selective mirror component only for a well-defined solar irradiance spectral range, while transparency is maintained for the rest of the spectrum.…”

Photonic crystals have the advantage of minimizing thermal losses from solar cells, reflecting the solar radiation that is not absorbed by the photovoltaic device. To optimize this optical response, photonic crystals are designed considering the relative position of the Bragg peak and the bandgap of the solar cell, under normal incident irradiation conditions. The aim of this research article was to determine experimentally the optical limits of a solar cell coupled to a photonic crystal acting as beam splitter. For that purpose, the photovoltaic system was characterized under indoor and outdoor conditions; angular dependence of the irradiation source was determined in each case, and both results were compared with good agreement. Moreover, other parameters such as irradiation spectrum and polarization of the light were investigated. The main conclusion is that photovoltaic performance is highly affected by the Bragg peak shifting and the profile is distorted, due to the angular dependence with the sun. These experimental limits must be considered at the early design stage to avoid performance losses.

“…The diamond shaped ring with circular pillar has been formulated and the QF of 377.5 is achieved [6]. Thus, the change of the rods radius and the ring shape may also promote to the change in the resonance identity of the depiction, non-identical types of pillars and rings have been sketched and Q factor about 400 is hooked which is Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/optcom satisfactory for integrated photonics applications [7][8][9][10][11] A new photonic crystal filter of X-shaped ring has been designed and investigated its performance for different configurations of the ring position like single ring with multiple configurations [12] i.e. single ring at the center and dual ring connected in parallel and serial.…”

Photonic crystal ring resonators are promising candidates for realizing all optical filters with acceptable transmission efficiency and quality factor values. In this paper, by putting a hexagon-shaped structure at the middle of on 7 × 7 square cavity we created a ring resonator structure and designed a channel drop filter. The drop wavelength of our filter is at 1550.4 nm, with transmission efficiency and quality factor equal to 94% and 707, respectively. Our structure is composed of dielectric rods immersed in air. Because in this kind of structures the dominant band gap is in TM mode, all of our simulations have been done in TM mode. The total footprint of our filter is 199.4 μm 2 , which makes it suitable for all optical integrated circuits.
