“…Of the literature more directly related to research and development of PV materials, there was an emphasis placed on the environmental impacts of manufacturing, often employing LCA techniques. Several studies highlighted the presence of "hotspots" in the development of emerging PV technologies with particular potential for justice concerns [31]. This included the environmental impacts of using glass substrates or precious metal contacts in cells [31], as well as the high rates of material wastage associated with spin-coating thin-film PV [32].…”

Achieving the energy transition sustainably requires addressing how new technologies may impact justice in the energy system. The Justice Underpinning Science and Technology Research (JUST-R) metrics framework was recently proposed to aid researchers in considering justice in early-stage research on energy technologies; however, case study evaluations of the framework revealed a desire from researchers to see metrics specialized to particular fields of study. Here, we refine metrics from the JUST-R framework to enhance its applicability to photovoltaic (PV) materials research. Metrics are reorganized to align with aspects of the research process (e.g., research team or source materials). For most metrics, baseline values are suggested to enable researchers to compare their project to competing technologies or standards at their institutions. These refinements are integrated into a tool to facilitate easier understanding and evaluation of justice considerations in early-stage PV research, which can serve as a template for evaluating other energy technologies.

“…After 20 min of treatment, the CQDs exhibited higher dye adsorption ability and displayed a further outstanding decolourization of MB and CR dyes. Although CQDs had limited capacity for dark reaction adsorption, the removal of dyes was nonetheless impressive because having a little amount of dyes adsorbed on the surface might act as a dye sensitizer, causing photosensitised degradation of dyes on the surfaces 39 , 73 , 74 . Amongst the organic dyes, because of their magnified photocatalytic activity as a result of their intense sunlight absorption, CQDs exhibited the best capacity to remove MB from the solution, along with the assistance from functional groups that make up the aromatic rings of MB, (C–S), (CN) and (CN= ), also known as a heterocyclic aromatic chemical compound.…”

The potentials of biomass-based carbon quantum dot (CQD) as an adsorbent for batch adsorption of dyes and its photocatalytic degradation capacity for dyes which are congo red (CR) and methylene blue (MB) have been conducted in this study. The CQDs properties, performance, behaviour, and photoluminescence characteristics were assessed using batch adsorption experiments which were carried out under operating conditions including, temperature, pH and dosage. The morphological analysis revealed that CQDs are highly porous, uniform, closely aligned and multi-layered. The presence of hydroxyl, carboxyl and carbonyl functional groups indicated the significance of the oxygenated functional groups. Spectral analysis of photoluminescence for CQDs confirmed their photoluminescent quality by exhibiting high excitation intensity and possessing greenish-blue fluorescence under UV radiation. The removal percentage of the dyes adsorbed for both CR and MB dyes was 77% and 75%. Langmuir isotherm and pseudo-second-order models closely fitted the adsorption results. Thermodynamics analysis indicated that the adsorption process was exothermic and spontaneous, with excellent reusability and stability. The degradation efficiency of CQDs on both dyes was more than 90% under sunlight irradiation and obeyed the first-order kinetic model. These results demonstrated CQDs to be an excellent adsorbent and outstanding photocatalyst for organic dye degradation.

“…One critical area of focus could be the development of advanced materials for both the photovoltaic and supercapacitor components of photocapacitors. Novel materials, such as metal halide perovskites, organic semiconductors, and two-dimensional materials, offer unique properties that could significantly improve the performance and sustainability of photocapacitor devices. − Furthermore, exploring the potential of sustainable, abundant, and low-cost materials, such as Earth-abundant metal oxides and sulfides, carbon-based materials, and bioderived polymers, for use in photocapacitor components might be a fruitful direction (Figure ). − …”

In response to the current trend of miniaturization of electronic devices and sensors, the complementary coupling of high-efficiency energy conversion and low-loss energy storage technologies has given rise to the development of photocapacitors (PCs), which combine energy conversion and storage in a single device. Photovoltaic systems integrated with supercapacitors offer unique light conversion and storage capabilities, resulting in improved overall efficiency over the past decade. Consequently, researchers have explored a wide range of device combinations, materials, and characterization techniques. This review provides a comprehensive overview of photocapacitors, including their configurations, operating mechanisms, manufacturing techniques, and materials, with a focus on emerging applications in small wireless devices, Internet of Things (IoT), and Internet of Everything (IoE). Furthermore, we highlight the importance of cutting-edge materials such as metal−organic frameworks (MOFs) and organic materials for supercapacitors, as well as novel materials in photovoltaics, in advancing PCs for a carbon-free, sustainable society. We also evaluate the potential development, prospects, and application scenarios of this emerging area of research.
