While existing reviews have summarized the synthesis and biomedical applications of CDs, none have systematically addressed their roles and mechanisms in ROS modulation.

Herein, a tandem dual Z-scheme heterostructure was synthesized by assembling cobalt porphyrin ([meso-tetra (4-sulfonate phenyl) porphyrinato], CoTPPS) on hollow-structured TiO₂@ZnIn₂S₄ (H-TiO₂@ZIS). The optimized H-TiO₂@ZIS@CoTPPS exhibits superior solar fuel evolution of 158.15 μmol_CO g⁻¹·h⁻¹ via the PCR process, which is superior to most reported TiO₂ and ZIS-based photocatalysts. The exceptional photocatalytic performance is ascribed to enhanced light absorption, elevated surface areas, directed charge separation, and improved CO₂ activation. Specifically, the double built-in electric field (IEF) and the Zn-O bond of dual Z-scheme structures facilitate fast charge separation.

However, the environmental sustainability of these IPV technologies remains underexplored, with the current lead-based versus lead-free debate confined to elemental considerations, overlooking life-cycle impacts and practical IPV requirements. This study presents the first comparative life-cycle assessment (LCA) addressing the lead-based vs. lead-free HP/HPD IPV dilemma, examining the environmental sustainability of absorbers, precursors, functional layers, and fabrication steps. A modelling framework is introduced to evaluate the net environmental gains (NEGs) of IPVs compared to the conventional battery-centric approach for powering smart devices. Our findings suggest that lead-free HP/HPD IPVs are not inherently more eco-friendly than their lead-based counterparts. We demonstrate that Pb- and Sn-based IPVs can achieve NEGs after just 3–4 weeks and 4–6 weeks, respectively, significantly outperforming mainstream IPVs. In contrast, the NEGs of Sb- and Bi-based IPVs align with mainstream IPVs, limiting their viability unless efficiencies increase to ∼40 %.

Among these, photocatalytic and photoelectrochemical (PEC) strategies hold a strong promise for converting CO₂ into valuable chemicals, thereby offering a potential solution to both energy and environmental challenges. Significant research has been conducted on sustainable photocatalysts capable of reducing CO₂ to value-added products. In this context, two-dimensional (2D) materials, owing to their unique optical, electrical, and structural properties, have emerged as versatile candidates for catalysing CO₂ reduction.

This is because perovskite films can be prepared using a low-temperature process and solution-based roll-to-roll fabrication with a superior power-to-weight ratio and high cost-effectiveness. Despite these advancements, the commercialization of f-PSCs remains constrained by several challenges associated with each sandwiched layer stacked in the device configuration, including the perovskite active layer, charge-transport layers (CTLs), flexible substrates, and electrodes. The delicate crystallization of perovskites on flexible substrates typically results in inhomogeneous nucleation and unwanted defect formation in perovskite films. Furthermore, the polycrystalline nature of perovskite films with numerous grain boundaries induces degradation sites and increases the susceptibility to mechanical fracture. Furthermore, CTLs at perovskite film interfaces encounter challenges such as weak adhesion, chemical instability, energetic alignment mismatches, and residual stress or strain. In addition, the top and bottom electrodes, including flexible substrates, remain susceptible to cracking and delamination under mechanical stress and real-world operating conditions. Consequently, f-PSCs exhibit fragility, reduced operational stability, and lower PCE than their rigid counterparts. These limitations present significant barriers to the industrial-scale production and commercialization of f-PSCs. In this review, we comprehensively discuss the existing challenges and progress regarding the material design of flexible devices based on the state-of-the-art results of single- and multijunction-based flexible perovskite devices. This involves flexible substrates and transparent electrodes, perovskite crystallization growth at low temperatures, synthesis of suitable CTLs, and interface passivation engineering to enhance performance and mechanical stability. Furthermore, we discuss large-scale production techniques, future prospects of flexible perovskite modules and encapsulation design, and the existing market potential to highlight the potential of f-PSCs for wearable and self-powered electronic devices in modern energy-harvesting technology.
