“…On the front side of SCs, several optical structures can serve as coloring agents facing the incident light. These include antireflection coatings, reflective filters composed of multilayer films with alternating low-and high-index materials, luminophores, [91] printable colorful coating formed by a mixture of polymers and dyes, [92] pigments, [93] subwavelength plasmonic resonators, [94,95] and optical microcavities. [96,97] The advantage of the external design strategies with reflective filter is the versatility and large degree of freedom in color manipulation for any type of underlying PV.…”

solar, wind, hydro, geothermal, and biomass, to enable a steady mitigation of greenhouse gas emissions, which are causing the planetary climate change and global warming. [5][6][7] Additionally, due to the economic development and the worldwide urbanization, a continuous rise of the global energy consumption across all key sectors, that is, power, heating, industry, and transport is occurring. This is expressed by an increase in the annual global electricity demand by 4.5% in 2021 corresponding to additional 1000 TWh. [4] Hence, strict criteria for the selection of competitive and abundant energy alternatives are imposed, requiring high yield at affordable prices. [8] The share of total renewables power generation excluding hydropower exceeded 3000 TWh in 2020, corresponding to almost 12% of the global electricity generation. [3] Considering an effective synergy between various sustainable energy candidates, solar photovoltaics (PV) have demonstrated great capabilities that can satisfy the requirements in the pathway towards 100% renewable electricity. [9][10][11][12] Owing to the research and development activities over the last decades, the power conversion efficiencies of solar cells (SC) have skyrocketed with a prolonged operation lifetime (>15 years) and a drastic plummeting in manufacturing costs (global average module selling price below $0.25 per W). [6,[13][14][15] The rapid universal deployment of PV resulted in a contribution of about 3.4% in the worldwide electricity generation in 2020. [3] Presently, the global installed PV capacity is approaching 1 TW and it is envisioned to reach ≈10 TW by 2030 and 30 to 70 TW by 2050. [16] Interestingly, along with massive electricity production using conventional solar power plants and rooftop solar panels, ancillary concepts of PV offer new strategies for supplying modern systems in versatile applications. [17][18][19] Moreover, diverse functionalities beyond solar energy harvesting can be afforded by adaptive PV, including aesthetic appearance, visual comfort and thermal management. [17,18,20,21] The distributed nature and the ubiquitous accessibility of multifunctional PV products are substantial features of solar PV in contrast to other renewable energies. However, traditional SCs dominating the market impose intrinsic optoelectronic and thermomechanical limitations, that prohibit their multifunctional utilization. To overcome these drawbacks, novel functional materials and innovative device architecture Solar photovoltaics (PV) offer viable and sustainable solutions to satisfy the growing energy demand and to meet the pressing climate targets. The deployment of conventional PV technologies is one of the major contributors of the ongoing energy transition in electricity power sector. However, the diversity of PV paradigms can open different opportunities for supplying modern systems in a wide range of terrestrial, marine, and aerospace applications. Such ubiquitous and versatile applications necessitate the development of PV technologies with customized desig...

“…Many of these strategies have been adapted from research on colorful conventional photovoltaics. [ 14,36 ] In case of colorful PSCs, the work of Jiang et al merits to be mentioned as they reach high PCEs of 11.6% (red) to 13.8% (blue) for a variety of colored PSCs by the integration of transparent top polymer electrodes of different thicknesses. [ 29 ] Recently, Yoo et al proved that these efficiencies could be enhanced even further.…”

The steadily growing market share of building‐integrated photovoltaics (BIPVs) places the aesthetics of solar modules in the focus of research and development. In this work, a colorization method based on inkjet‐printed reflective pigments is adapted for the emerging perovskite photovoltaics. Herein, not only excellent control of color impression, brightness, and pattern is demonstrated, but also angle invariant color perception, which makes the presented approach stand out among the many published colorization strategies for perovskite solar cells (PSCs). Compared to uncolored reference solar cells, bright magenta and yellow PSCs display a remarkable relative power conversion efficiency (PCE) of up to 65% and more than 11% absolute PCE. Moreover, PSCs with more BIPV‐relevant coloring patterns such as a mimic of a marble or corten steel surfaces are demonstrated. The colorization method presented is inexpensive and ready for scalable solar module production. To demonstrate the scalability of the proposed concept, a small‐area perovskite solar module (4 cm2 aperture area) in white marble optics exhibiting a PCE of almost 14% as a potential application is presented.

“…BIPVs that use conventional PV modules cannot hide the black solar cells, and are therefore not acceptable to architectural designers. According to a survey on the BIPV challenges in the architecture field, the perceived color and decorative features of BIPVs are considered high-priority factors [5,14,15]. Customers prefer BIPV modules that are similar in color and texture to existing exterior materials [7].…”

This paper suggests a novel way to manufacture power-efficient building-integrated photovoltaic (BIPV) modules that are aesthetically acceptable for use in zero-energy buildings (ZEBs). An optical pattern is formed using additive manufacturing (AM) to maximize the number of sunrays that reach the solar cells and to hide cells beneath the pattern. The optical pattern was optimized by simulation, then selected PV modules were fabricated to ensure that they met the optimal optical pattern conditions. Increase in pattern angle and lens space yielded increase in the output power of the PV module, but reduced the aesthetic functionality. This color BIPV technology is expected to help expand the BIPV market and reduce carbon for “net zero” objectives.
