“…With a J SC of 22.59 mA cm −2 , a V OC of 1.04 V, an FF of 72.0%, the PCE of the colorful PSC reaches 16.94%, which is larger than the efficiencies for all the colorful PSCs reported in the literature till now [7,8,[15][16][17][18][19][20][21][22][23][24][25]. Specifically, the colorful PSCs with a bifunctional polymer counter electrode displayed PEC values ranging from 12.8% to 15.1% (from red to blue) [8] while most of the reported colorful PSCs exhibited PEC values less than 13%. Due to the hysteresis in the J-V measurement, the stabilized output efficiency of the solar cell was considerably lower than that of the PCE obtained from the J-V curve.…”

“…Impressively, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has been rapidly boosted from the initial 3.8% to 23.3% [4,5]. With the maturing of the PSC technology, it is highly desirable to develop colorful solar cells to satisfy the requirements of aesthetic purposes in applications including building integrated photovoltaics and wearable electronics [6][7][8][9]. The broad optical absorption and the large absorption coefficient of perovskites usually lead to high-efficiency cells with dark-brown colors.…”

“…Nevertheless, these colorful PSCs based on structural color still suffered from severe impairment of the cell performance, thus exhibiting efficiencies commonly less than 13%. It is noteworthy that Zhou et al [8] realized efficient colorful PSCs by using a transparent conducting polymer as both a top electrode and a spec-trally selective antireflection coating. The obtained colorful PSCs displayed PEC values ranging from 12.8% to 15.1% (from red to blue) with a maximum stable PCE of 14.3% achieved for the blue colored PSC.…”

The rapid development of perovskite solar cells (PSCs) has stimulated great interest in the fabrication of colorful PSCs to meet the needs of aesthetic purposes in varied applications including building integrated photovoltaics and wearable electronics. However, it remains challenging to prepare high-efficiency PSCs with attractive colors using perovskites with broad optical absorption and large absorption coefficients. Here we show that high-efficiency PSCs exhibiting distinct structural colors can be readily fabricated by employing TiO 2 nanobowl (NB) arrays as a nanostructured electron transport layer to integrate with a thin overlayer of perovskite on the NB arrays. A new crystalline precursor film based on lead acetate was prepared through a Lewis acid-base adduct approach, which allowed for the formation of a uniform overlayer of high-quality CH 3 NH 3 PbI 3 crystals on the inner walls of the NBs. The PSCs fabricated using the TiO 2 NB arrays showed angle-dependent vivid colors under light illumination. The resultant colorful PSCs exhibited a remarkable photovoltaic performance with a champion efficiency up to 16.94% and an average efficiency of 15.47%, which are recordbreaking among the reported colorful PSCs.

“…Under white light exposure, the double grating design enables the perovskite solar cells with structural color from both the front glass view and the back metal electrode view, as shown in Figure a, which arises from the grating diffraction of the grating PDMS antireflection layer and grating TiO 2 scaffold, respectively. The special architecture provides an alternative solution for fabricating colorful photovoltaic devices without sacrificing device performance, which holds great promise for the integration of photovoltaics into building and aesthetically appealing applications . The grating PDMS antireflection layer has a hydrophobic property with a contact angle as high as 123°, which is much higher than that (19°) of bare glass (Figure b).…”

Organic-inorganic halide perovskite solar cells are one of the most efficient photovoltaic devices, and their power conversion efficiency (PCE) continues to grow rapidly due to the optimization of device architecture and functional materials. The involved optical design has an important impact on performance by affecting the light harvesting capability. Here, demonstrated is a simple and effective strategy to boost device performance from the perspective of light management. A diffraction grating pattern into the TiO 2 scaffold and antireflection layer is simultaneously introduced to construct a double grating design for perovskite solar cells. The grating pattern obtained using a commercial compact disk as the hard mold can modulate light transport by enhancing the light transmittance and, thus, light absorption in perovskite solar cells. The grating pattern-induced light trapping can significantly increase the short-circuit current density and PCE by 4.8% and 7.9%, respectively, on average. The present work develops a feasible method by tailoring the morphology-related optical property to further improve the performance of perovskite solar cells. The double grating design can also generate structural color and can provide an alternative solution for fabricating colorful solar cells.

“…The transparent conducting polymer stacks of (poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate)) served as the top electrode simultaneously as an antireflectance coating. Altering the thickness resulted in the suppression of the reflectance at a specific wavelength, thus the vivid color emerged . Especially, Wang et al utilized the antireflective structure to analyze small molecules by mass spectrometry …”

known that the optical properties related refractive index is an important parameter for ordered micro/nanostructures. Commonly, organic substances own lower refraction. Aiming at improving which, researchers introduce highly polarizable heteroatoms or rigid aromatic moieties. However, the maximum of refractive index is limited to 1.54-1.60, [3] which is far from the requirements of rapidly developing technologies. [4] Incorporation of inorganic materials with relative higher refractive index (TiO 2 , ZnO, ZnS, graphene nanoparticles, and Si) into an organic matrix is capable of enlarging the optical parameters to a great extent, generally up to a value of 2.5-3.0, [5] which offers more chances for the fabrication of novel ordered micro/nanostructures. Photonic crystals (PCs), for example, regularly arrange materials of high and low dielectric constants on the order of the wavelength of light. The photonic bandgap (PBG) prohibiting the propagation of light results from the sufficient dielectric contrast and appropriate geometry. The structural color therefore generates. Manipulating the propagation of light via micro/nanostructures meets the requirements for modern optical devices. [6] As a result, more efforts have been applied to devices consisting of micro/nanostructures of multiple materials, such as synthetic materials and biomaterials. [7] Besides optical properties, the strength and toughness of ordered micro/nanostructures are also improved based on the hybrid material. Meanwhile, the electric and magnetic features of inorganic dopants can also exactly assist the adjustability. Therefore, the hybrid can significantly improve performance compared with its constituent.This review emphasizes on applications sought (sensing, imaging, communication, photoelectricity, etc.), the materials used (silicon, metals, polymers, etc.), and the preparation methods employed (patterning, etching, deposition, etc.). We present an attempt to classify and compare some intensively reported micro/nanostructures of hybrid materials and/or heterogeneous structures, along with recent important developments in literatures. It is organized as follows: First, we summarize some fundamental physical principles and concepts in brief. Second, we particularly highlight artificial and natural laminar structures, represented by Bragg stacks (BSs) and butterfly wings, which have drawn much attention in the latest literatures. Next, the focus shifts to the preparation routes and materials adoption of colloidal crystals and their derived periodic arrays. A few examples of highly functional materials Recent advances in manufacturing and technology of ordered hybrid micro/ nanostructures have acquired many breakthroughs. With the aid of the cooperation of various materials, the ordered hybrid micro/nanostructures exhibit high-quality performance and mechanical stability and allow the modulation on the light-matter interaction in a controllable manner, thereby enabling a wide variety of innovative applications.
