Summary: Poly(GVGVP), a synthetic elastin-like polypentapeptide, was studied for its interaction with collagen in blends using viscometry, FTIR, SEM, and XRD techniques. The thermal characteristics and stability of the blends were also analyzed using DSC and TGA. The results showed that blending with polypentapeptide caused shifts in the positions of amide A and B bands in the FTIR spectra of collagen. The blends exhibited characteristic glass transition temperatures and thermal stability. Viscosity evaluations demonstrated a strong association between collagen and poly(GVGVP), highlighting the potential for creating novel materials for biomedical purposes.

Summary: This study investigates the effects of end-capped modifications on a high molecular weight polymer donor and demonstrates a successful strategy to improve the performance of non-fullerene solar cells. By introducing end-capped groups, the aggregated behavior of the polymer donor was finely tuned, leading to enhanced miscibility with the acceptor and reduced non-radiative recombination and energy loss. As a result, the end-capped polymer achieved higher open-circuit voltage and power conversion efficiency compared to the non-end-capped parent polymer.

Summary: Due to their outstanding thermal stability and mechanical properties, All-polymer solar cells (All-PSCs) have attracted increasing attention. However, the prevailing polymer acceptors BTTP-based polymers, have limitations in terms of energy levels and figure of merit (FOM) which restricts the selection of donor polymers. Therefore, the development of low-cost BTP-based polymer acceptors has significant importance.

Summary: This study improves the molecular structure and orientation of polymer donors through a random copolymerization strategy, leading to enhanced performance of non-fullerene polymer solar cells. The resulting terpolymer donor with a specific ratio of BDD-based monomer demonstrates a dominant face-on orientation and weakened aggregations, resulting in improved carrier transport and morphology when blended with acceptor. This strategy involving an extra component can revive the efficiency of oligothiophene-based conjugated polymers in non-fullerene solar cells.

Summary: Tailoring the blend morphology of bulk heterojunctions (BHJs) has been successful in improving the thermal stability of organic solar cells (OSCs). In this study, thermally stable OSCs were demonstrated in a ternary blended system comprising low-crystalline semiconducting polymers (asy-PNDI1FTVT and PTB7-Th) and a non-fullerene acceptor (Y6). The optimized blend system showed a well-mixed morphology at the BHJ, leading to enhanced charge dissociation and improved fill factor and power conversion efficiency. The ternary blend of PTB7-Th:Y6:asy-PNDI1FTVT suppressed phase separation, resulting in negligible burn-in loss and performance degradation under thermal stress. The experiments showed that the devices retained over 90% of their initial efficiencies after 100 hours at 65 degrees C, indicating significant potential for the development of thermally stable OSCs with reasonable efficiency.

In this study, a new concept for organic optical memory design was presented, using a redox-active photochromic molecular switch triggered by light-induced charge separation. The developed optical memory device showed impressive switching coefficient and memory window. These results demonstrate the potential of using light-induced charge separation for photoisomerization and pave the way for new light-triggered molecular memory devices.

Summary: Despite the dominance of bulk-heterojunction (BHJ) structure in the fabrication of organic solar cells (OSCs) due to its higher power conversion efficiency (PCE), this study investigates four different types of bilayer OSC structures using sequential processing (SP) with an additive bilayer and demonstrates considerably enhanced device performance. Through the introduction of a wide bandgap polymer and PCBM materials, the PCE of the conventional bilayer structure is improved from 2.88% to 6.62%. Moreover, remarkable PCEs of 8.78% and 15.16% for PTB7-Th/PCBM and PM6/Y6 bilayer OSCs, respectively, are achieved using the SP with additive bilayer method, successfully addressing the inhomogeneity issues of the BHJ structure.

Summary: The current state-of-the-art organic solar cells (OSCs) commonly use halogenated materials and solvents, which can be corrosive and harmful to the environment. Therefore, it is meaningful to explore and develop efficient and stable OSCs based on halogen-free materials and solvents. Researchers have successfully demonstrated that fully halogen-free OSCs can achieve efficient performance with an efficiency of 10.42% and superior thermal stability, due to the use of nonhalogenated active blend and processing solvent, which inhibit corrosion and preserve the initial efficiency for a prolonged period of time under high temperature conditions.

Summary: We synthesized three linear triblock terpolymers, two of the ABC type and one of the BAC type, consisting of chemically incompatible blocks such as polystyrene (PS), poly(butadiene) of exclusively -1,2 microstructure (PB1,2), and poly(dimethylsiloxane) (PDMS). These terpolymers were characterized using multiple molecular characterization techniques, and their self-assembly behavior was studied using transmission electron microscopy and small-angle X-ray scattering experiments. Furthermore, post-polymerization chemical modification reactions were carried out on the PB1,2 segments, and the successful incorporation of -OH groups and preparation of polymeric brushes were confirmed using various molecular, thermal, and surface analysis measurements. This study represents the first synthesis and chemical modification of such triblock terpolymers and provides a promising route for designing polymers for nanotechnology applications.

Summary: In this study, an efficient approach for evaluating the intrinsic photostability of organic absorber materials used in photovoltaic applications is presented. Using a series of structurally related conjugated polymers and complementary techniques, important material structure-photostability relationships were established. It was found that the introduction of alkoxy, thioalkyl, and fluorine substituents has a negative effect on the material's photostability. The developed techniques can be further applied to systematically screen different materials and provide guidelines for designing more stable absorber materials for organic solar cells.
