“…These methods include, but are not limited to, atomic layer deposition [106][107][108][109], chemical vapor deposition [11,84,108,110], electrochemical deposition [97,[111][112][113][114], and sol-gel techniques ( Figure 8) [85,87,91,93,115,116]. Cai et al demonstrated an improved convective self-assembly technique to fabricate composite heterostructures, and they showed that they could fabricate both opaline and inverse opaline heterostructures with long range ordering (>100 × 100 µm²) [93].…”

“…They concluded that the wavelength selective photonic crystal concentrator can improve the maximum power of the DSSC by more than five times while retaining a stable high performance ( Figure 13) [135]. The use of self-assembled colloidal crystals in dye sensitized solar cells (DSSCs) has also drawn much interest in recent years [106,108,[129][130][131][132][133]. DSSCs are an interesting alternative to conventional solid state semiconductor photovoltaic devices largely due to their low cost of production [134].…”

Abstract:The assembly of colloidal building-blocks is an efficient, inexpensive and flexible approach for the fabrication of a wide variety of photonic materials with designed shapes and large areas. In this review, the various assembly routes to the fabrication of colloidal crystals and their post-assembly modifications to the production of photonic materials are first described. Then, the emerging applications of the colloidal photonic structures in various fields such as biological and chemical sensing, anti-reflection, photovoltaics, and light extraction are summarized.

“…This gives photons a higher probability of being absorbed in this layer, 77 -79 improving an effi ciency that is limited, in part, because the organic dyes used in DSSCs are poor absorbers of red and near-infrared light. 80 Mihi et al 78 increased DSSC power effi ciency by using a porous PhC coupled to the working electrode. Guldin et al 79 achieved similar results by fabricating a double-layer DSSC using titania inverse opals and mesoscopic block-copolymer-patterned titania.…”

MATERIALS BY DESIGN: USING ARCHITECTURE IN MATERIAL DESIGN TO REACH NEW PROPERTY SPACES 1123MRS BULLETIN • VOLUME 40 • DECEMBER 2015 • www.mrs.org/bulletin S Similarly, phononic crystals (PnCs) are artifi cial periodic structures composed of elastic materials, in which mechanical waves within a specifi c frequency bandwidth are forbidden from propagating. This prohibited frequency range is termed the phononic bandgap (PnBG) and enables sound, and often heat, to be controlled, allowing for the creation of more effi cient fi lters, waveguides, and resonant cavities.The combination of geometry-including lattice type, topology, and scale-with material properties determines the ultimate behavior of architected materials. Beyond controlling wave propagation and mechanical properties, structural design and microstructural parameters are signifi cant for many applications, including battery electrodes, supercapacitors, and other electrochemical (e.g., electrochromic) devices.

“…This feature is derogated by reducing film thickness in thin-film solar cells such as dye sensitized solar cell (DSSC); therefore, many approaches are made to improve it. For example, porous active layer with high surface area [1][2][3], hierarchically nanostructures as photoanode [4][5][6], scattering layers on the top of active film [7][8][9], plasmonic photoanodes [10][11][12] and photonic crystal photoanodes [13][14][15] have been applied for changing the optical design of the DSSC to optimize its light absorbance. Since the mentioned approaches have some limitations like high reflectance loss and low dye adsorption, researchers are still extensively eager to explore the new light trapping structures as photoanode.…”

The light harvesting efficiency is counted as an important factor in the power conversion efficiency of DSSCs. There are two measures to improve this parameter, including enhancing the dye-loading capacity and increasing the light trapping in the photoanode structure. In this paper, these tasks are addressed by introducing a macro-porous silicon (PSi) substrate as photoanode. The effects of the novel photoanode structure on the DSSC performance have been investigated by using energy dispersive X-ray spectroscopy, photocurrent-voltage, UV-visible spectroscopy, reflectance spectroscopy, and electrochemical impedance spectroscopy measurements. The results indicated that bigger porosity percentage of the PSi structure improved the both anti-reflective/light-trapping and dye-loading capacity properties. PSi based DSSCs own higher power conversion efficiency due to its remarkable higher photocurrent, open circuit voltage, and fill factor. Percent porosity of 64%, PSi(III), resulted in nearly 50 percent increment in power conversion efficiency compared with conventional DSSC. This paper showed that PSi can be a good candidate for the improvement of light harvesting efficiency in DSSCs. Furthermore, this study can be considered a valuable reference for more investigations in the design of multifunctional devices which will profit from integrated on-chip solar power.
