Perovskite (PVK) solar cells (PSCs) have garnered considerable research interest owing to their cost-effectiveness and high efficiency. A systematic annual review of the research on PSCs is essential for gaining a comprehensive understanding of the current research trends. Herein, systematic analysis of the research papers on PSCs reporting key findings in 2023 was conducted. Based on the results, the papers were categorized into six classifications, including regular n-i-p PSCs, inverted p-i-n PSCs, PVK-based tandem solar cells, PVK solar modules, device stability, and lead toxicity and green solvents. Subsequently, a detailed overview and summary of the annual research advancements within each classification were presented. Overall, this review serves as a valuable resource for guiding future research endeavors in the field of PSCs.

“…The incorporation of gel‐fibers into artificial crystals also improve their toughness [16,18,52,53] . Using the transmission electron microscopy‐scanning probe microscopy (TEM‐SPM) method, rupture time is measured by in‐situ observation of the calcite crystal before and after rupture (Figure 3a–f).…”

“…To investigate and simulate this biomineralization process, crystals are prepared in gel medium, [7–15] which results in gel‐networks being incorporated into the crystals. This incorporation also enhances both the toughness and stability of the crystals [16–18] . Furthermore, guest materials such as nanoparticles (NPs) or dye molecules, which are intrinsically incompatible with crystals, can be introduced into the gel‐media before crystallization.…”

In nature, the biominerals are always organic‐inorganic crystal composites. Inspiring by this biomineral structure, the functionalized single crystal can be synthesized by the gel‐grown method, which also leads to the incorporation of gel‐networks into the crystal. The gel‐incorporation expands the variety of functionalized substances that can be incorporated into crystals, such as the nanoparticles without surface modification. And the gel‐incorporation promotes the dye or fluorescent molecules to be isotopically incorporated into crystals. Besides, the gel‐incorporation also enhances the toughness and stability of crystals, even endowing protein crystals with the self‐healing property. More importantly, the recent research indicated that the incorporation of the gel‐networks enhances their charge effects on the crystal morphology control. In general, the gel‐incorporation not only expands the scope of functionalization of crystal materials, but also extends the application scenario. Therefore, preparing the single crystal with gel‐incorporation is a remarkable strategy for synthesizing functionalized crystals with the better mechanical property and controllable morphology.

“…To survive the impact, a material must exhibit high strength and toughness at high strain rates to effectively dissipate the kinetic impact energy. A prevalent approach involves designing high-energy-dissipating materials via various toughening mechanisms, such as bioinspired multilayer or bouligand assemblies, − fiber reinforcement, − phase separation, , and molecular clogging . However, the intrinsic rigidity of these materials greatly restricts their applicability in modern wearable and buffering scenarios, which demand adaptability and compliance with the moving human body or underlying objects.…”

Impact-stiffening materials that undergo a strain rate-induced soft-to-rigid transition hold great promise as soft armors in the protection of the human body and equipment. However, current impact-stiffening materials, such as polyborosiloxanes and shear-thickening fluids, often exhibit a limited impact-stiffening response. Herein, we propose a design strategy for fabricating highly impact-stiffening supramolecular polymer networks by leveraging high-entropy-penalty physical interactions. We synthesized a fully biobased supramolecular polymer comprising poly(α-thioctic acid) and arginine clusters, whose chain dynamics are governed by highly specific guanidinium-carboxylate salt-bridge hydrogen bonds. The resulting material exhibits an exceptional impact-stiffening response of ∼2100 times, transitioning from a soft dissipating state (21 kPa, 0.1 Hz) to a highly stiffened glassy state (45.3 MPa, 100 Hz) with increasing strain rates. Moreover, the material's high energy-dissipating and hot-melting properties bring excellent damping performance and easy hybridization with other scaffolds. This entropy-driven approach paves the way for the development of nextgeneration soft, sustainable, and impact-resistant materials.
