This work demonstrates a general and effective approach to activate inert polymer chains for further reactions through electrochemically driven radical generation and radical transfer reactions. The generated radical-containing polymer chains show capacity for further polymer reactions and preparation of polymer hybrids.

A novel, aqueous precursor system (Pb(NO3)2 + water) is developed to replace conventional (PbI2 + DMF) for fabricating methylammonium lead iodide (MAPbI3) perovskite solar cells (PSCs). When the morphology and surface coverage of the Pb(NO3)2 film was controlled during coating, a power conversion efficiency of 12.58% under standard conditions (AM1.5, 100 mW cm(-2)) was achieved for the PSC.

A series of new phenothiazine-based dyes (HL5-HL7) with double acceptors/anchors have been synthesized and used as the sensitizers for highly efficient dye-sensitized solar cells (DSSCs). Among them, the HL7-based cell exhibits the best efficiency of 8.32% exceeding the N719-based cell (7.35%) by ∼13%.

A bifunctional TiO(2) layer having an inner compact layer and an outer anchoring layer coated on fluorine-doped tin oxide (FTO) glass could reduce the charge recombination and interfacial contact resistance between FTO and the main TiO(2) layer; photoelectron conversion efficiency of cell was increased from 7.31 to 8.04% by incorporating the bifunctional layer.
