“…for the window industry. However, CIELAB (CIE L*a*b*) color coordinate system is the most comprehensive color space that displays not only chromaticity but also brightness values [49,50]. For this reason, we measured the color coordinates (shown in Figure 7) by color spectrophotometer in the CIELAB system.…”

Aesthetic appearance of building-integrated photovoltaic (BIPV) products, such as semitransparent PV (STPV) glass, is crucial for their widespread adoption and contribution to the net-zero energy building (NZEB) goal. However, the visual distortion significantly limits the aesthetics of STPV glass. In this study, we investigate the distortion effect of transparent periodic-micropattern-based thin-film PV (PMPV) panels available in the market. To minimize the visual distortion of such PMPV glass panel types, we design and develop an aperiodic micropattern-based PV (APMP) glass that significantly reduces visual distortion. The developed APMP glass demonstrates a haze ratio of 3.7% compared to the 10.7% of PMPV glass. Furthermore, the developed AMPV glass shows an average visible transmittance (AVT) of 58.3% which is around 1.3 times higher than that of AMPV glass (43.8%). Finally, the measured CIELAB values (L* = 43.2, a* = −1.55, b* = −2.86.) indicate that our developed AMPV glass possesses excellent color neutrality, which makes them suitable for commercial applications. Based on the characterization results, this study will have a significant impact on the areas of smart window glasses that can play a vital role in developing a sustainable environment and enhancing the aesthetical appearance of net-zero energy buildings (NZEB).

“…Although the ultrathin layer of a-Si exhibited a relatively low PCE, the high angular tolerance compensated for the weakness. The investigation of BIPV applications for a-Si:H solar cells summarized the specifications for cell colors, efficiencies, transparency, and the size of the cells (Figure 8d) (Yeop Myong & Won Jeon, 2015). The aesthetic color design of 1.43 m 2 of the cell module was investigated.…”

Photovoltaic (PV) systems, which directly convert solar light into electricity, are one of the most attractive renewable energy sources to fulfill the increased demand for clean energy. The accumulated installation of PV systems has expanded rapidly, reaching over 700 GW in 2020. Although black colored PVs maximize energy generation by harvesting a broad range of solar light, their monotonous color limits their installation in urban areas and portable devices where the harmonization of color with neighboring exterior elements is a high priority. Moreover, it is not suitable for covering transparent area of buildings, such as window and curtain wall. Hence, the demand for aesthetic PV systems is increasing significantly. In this review, we focus on the current status of colored PV systems and their prospects for aesthetic energy harvesting system. This work reviews possible approaches to realize colored PV systems by implementing semitransparent cells, selective reflective films, and luminophores. Additionally, the research progress to minimize light sacrifice for color production has been investigated. Moreover, the technical limitations of each technology for colored PV systems are presented in terms of color purity and efficiency. Finally, obstacles to commercialization and their solutions are discussed. Therefore, this study provides a crucial review of the latest developments and current status in the field of colored PV systems.

There is an intense need to optimize agrivoltaic systems. This article describes the invention of a new testing system: the parametric open source cold-frame agrivoltaic system (POSCAS). POSCAS is an adapted gardening cold-frame used in cold climates as it acts as a small greenhouse for agricultural production. POSCAS is designed to test partially transparent solar photovoltaic (PV) modules targeting the agrivoltaic market. It can both function as a traditional cold frame, but it can also be automated to function as a full-service greenhouse. The integrated PV module roof can be used to power the controls or it can be attached to a microinverter to produce power. POSCAS can be placed in an experimental array for testing agricultural and power production. It can be easily adapted for any type of partially transparent PV module. An array of POSCAS systems allows for the testing of agrivoltaic impacts from the percent transparency of the modules by varying the thickness of a thin film PV material or the density of silicon-based cells, and various forms of optical enhancement, anti-reflection coatings and solar light spectral shifting materials in the back sheet. All agrivoltaic variables can be customized to identify ideal PV designs for a given agricultural crop.
