Sulfur-fused perylene diimides (PDIs) having the formula 2PDI-nS, wherein n is an integer. Such sulfur-fused PDIs (e.g., 2PDI-2S, 2PDI-3S, and 2PDI-4S) are incorporated as electron acceptors in an active region of a bulk heterojunction solar cell and/or as an electron transport layer. Example solar cells exhibit a power conversion efficiency above 5% and a fill factor above 70% (a record high for non-fullerene bulk heterojunction solar cell devices) when 2PDI-nS is used as the electron acceptor. In addition, the solar cells exhibit low open circuit voltage (V) loss.

An electrochemical cell includes an anode having a metal material having an oxygen containing layer. The electrochemical cell also includes a cathode and an electrolyte. The anode includes a chemically bonded protective layer formed by reacting a D or P block precursor with the oxygen containing layer.

Chemical protection of metal surface

A composition for use in an electrochemical cell is disclosed wherein the composition includes a clean metal substantially free of impurities and a layer of protective material in contact with the clean metal. Further disclosed is an electrochemical cell including a metal film comprising a clean metal substantially free of impurities. The electrochemical cell may further include an electrolyte and a layer of protective material disposed between the electrolyte and the metal film. A process for manufacturing an electrode is further disclosed including preparing a metal film comprising a clean metal substantially free of impurities and depositing a layer of protective material on to the metal film.

Electrode compositions and processes

N-bridged PCBMs are prepared by the cycloaddition of an organic azide to C. The N-bridged PCBMs are imino PCBMs, exemplified by an isomeric mixture of [5,6]-open APCBM and [6,6]-closed APCBM. An organic electronic material containing a fullerene adduct, such as an organic field effect transistor or an organic photovoltaic device, is provided containing the N-bridged PCBM as the fullerene adduct.

A method for the synthesis of well-defined rod-coil block copolymers consisting of P3HT donor and Cacceptor chromophores (P3HT-b-P(SA)-C) in a molecular architecture is reported for use in bulk-heterojunction (BHJ) solar cells. In thin films of the resulting block copolymer, reproducible self-assembly into well-defined 'nanofibrils' is observed. This is the first example of a block copolymer containing a Cderivative that shows exclusively a nanofibrilar structure. A substantial improvement in device performance is achieved when the block copolymer is used as a 'surfactant' for controlling the interface morphology of the P3HT:PCBM donor-acceptor phase domains within the composite.

Thermally re-mendable cross-linked polymeric materials that can be repeatedly mended or repaired by simple thermal treatment. The polymeric materials are made by polymerizing furan monomers and maleimide monomers via the Diels-Alder (DA) reaction wherein the furan monomers have at least three furan moieties and the maleimide monomers have at least three maleimide moieties. The intermonomer linkages that form between the furan and maleimide monomers are thermally reversible and do not require the addition of catalysts, additional monomer or special surface treatments.
