Summary: In this review, the focus is on renewable sources of energy with an emphasis on solar cell applications. Specifically, the possible future directions for the development of dye-sensitized solar cells (DSSCs) are discussed. DSSCs have gained significant research attention due to their importance in energy conversion. The review discusses the use of metal dye sensitizers, metal-free organic dyes, and natural dyes in DSSCs, highlighting their low cost, simplicity of preparation, low toxicity, and ease of production. Computational studies are also reviewed, emphasizing their contribution to the development of new dye sensitizers. The article presents a conceptual understanding of the development and working principle of photoactive DSSC materials, along with examples of studies on different dye sensitizers using both scarce to abundant metal-based dyes and metal-free organic dyes for n-type and p-type DSSCs. The choice of organic dyes, including donor, spacer, or acceptor, is discussed, and the potential of dual donor-based dyes is presented.

Summary: Two Schiff base complexes, [CuL2] (Cu-Sal) and [CoL3] (Co-Sal), were synthesized and characterized. Crystal structure analysis showed a square planar geometry around Cu(ii) and various intermolecular non-covalent interactions in Cu-Sal. Both complexes were used as sensitizers in TiO2 based dye sensitized solar cells (DSSCs), and Co-Sal exhibited better photovoltaic performance than Cu-Sal due to improved light absorption and dye loading.

Summary: Bulky N-substituents of 4-(hexyloxy) phenyl-substituted and 4-(hexylthio)phenyl-substituted triphenylamine were successfully introduced into double-anchored phenothiazine dyes as capping moieties for metal-free organic sensitizers in dye-sensitized solar cells. The N-substituent of 4-(hexyloxy)phenyl-substituted TPA provided the best steric matching and resulted in a compact dye packing and an integrated shelter layer on the TiO2 surface. The DSSC performance achieved with this modification was higher than that of the reference N719-based and HL5-based DSSCs.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
