“…[154][155][156][157][158][159] In 2013, Martorell et al [160] developed a new strategy by using nonperiodic photonic crystals to trap near-infrared and nearultraviolet photons for the OSCs. The photon management provided by the nonperiodic 1D structure of five layers is sufficient to maintain the light-harvesting capacity of the semitransparent device to 77% of that of the opaque cell.…”

Flexible and semitransparent organic solar cells (OSCs) have been regarded as the most promising photovoltaic devices for the application of OSCs in wearable energy resources and building‐integrated photovoltaics. Therefore, the flexible and semitransparent OSCs have developed rapidly in recent years through the synergistic efforts in developing novel flexible bottom or top transparent electrodes, designing and synthesizing high performance photoactive layer and low temperature processed electrode buffer layer materials, and device architecture engineering. To date, the highest power conversion efficiencies have reached over 10% of the flexible OSCs and 7.7% with average visible transmittance of 37% for the semitransparent OSCs. Here, a comprehensive overview of recent research progresses and perspectives on the related materials and devices of the flexible and semitransparent OSCs is provided.

“…We denote the PC structure by AB n , where A and B indicate MNG materials with thickness d A and PIMs with thickness d B , respectively, and n is the number of periods. Drude model is used to describe the effective parameters of MNG materials [16][17][18][19] as…”

“…Therefore, the polarization properties of reflected light can be obtained by comparing the reflection phase shift of TE or TM wave. For an infinite PC structure AB n (n → ∞), according to the Bloch's theorem, the dispersion at any incident angle follows the relation [17,19] cos…”

“…Compared with positive-index materials (PIMs), SNG materials are opaque and they only support evanescent modes since the wave vectors in SNG materials are imaginary. However, special characteristics can be found in multilayered periodic structures containing SNG materials [16][17][18][19][20][21][22][23]. 1D PCs, which are composed of alternate SNG materials and PIMs, have been studied by investigating the band structures, the transmission and reflection intensity, and the field distributions [20][21][22][23].…”

The phase shift upon reflection from one-dimensional photonic crystal composed of alternating layers of munegative materials and positive-index materials is numerically investigated. It is found that the phase difference between TE and TM reflected waves can remain constant in a rather wide frequency range within the singlenegative gap of the proposed structure. Such property can be used to design broadband phase retarder. By varying the incident angle, the phase difference of the retarder can be adjusted from 0 to π, while the working frequency range of the retarder remains almost unchanged. Moreover, by varying the scaling factor or the thickness ratio of the two constituent materials, the working frequency range of the phase retarder can be conveniently tuned.

“…Comparing with the propagating waves in conventional materials and DNG materials, electromagnetic waves in SNG materials are evanescent waves since their wave vectors are complex. There are many researches on photonic crystals (PCs) consisting of metamaterials due to their intriguing properties of manipulating photons [6][7][8][9][10][11].…”
