“…Inferior P3HT purity is sometimes suggested to affect charge transport, however an X-ray Photoelectron Spectroscopy (XPS) survey scan shows that the material used here is free of impurities ( Figure S1, Supporting Information). [ 23 ] Turning our attention now towards a more detailed chemical analysis by XPS of the best performing devices (60 wt% precursor concentration), a composition of C:N:Pb:I:Cl = 1.04:1:1.05:2.02:0.99 can be derived by integrating appropriate core level spectra representing the different atomic species (with the exception of hydrogen). This experimental result agrees very well with the expected nominal stoichiometry (1:1:1:2:1), thus indicating the presence of a high quality material that can be used to further explore its electronic structure.…”

Organometal halide perovskites have tremendous potential as light absorbers for photovoltaic applications. In this work we demonstrate hybrid solar cells based on the mixed perovskite CH3 NH3 PbI2 Cl in a thin film sandwich structure, with unprecedented reproducibility and generating efficiencies up to 10.8%. The successfulness of our approach is corroborated by the experimental electronic structure determination of this perovskite.

“…31 During casting and subsequent annealing processes, there is a process of crystallization, alignment of polymer chains, and limited self-organization, which changes the structure to favor exciton collection and charge transport. 50,51 This process is extremely sensitive to the solvent used, 52,53 variations in composition, 54 annealing, [55][56][57][58][59] chemical-structure variations, [60][61][62][63] purities, 64 and processing conditions, 65 to name but a few of the related parameters when dealing with what is a fundamentally unstable system. 66 The seminal work by Yang et al demonstrated the necessity of controlled mixing of the acceptor and donor in the composite.…”

A simple overview of the methods used and the expected benefits of block copolymers in organic photovoltaic devices is given in this review. The description of the photovoltaic process makes it clear how the detailed self-assembly properties of block copolymers can be exploited. Organic photovoltaic technology, an inexpensive, clean and renewable energy source, is an extremely promising option for replacing fossil fuels. It is expected to deliver printable devices processed on flexible substrates using high-volume techniques. Such devices, however, currently lack the long-term stability and efficiency to allow organic photovoltaics to surpass current technologies. Block copolymers are envisaged to help overcome these obstacles because of their long term structural stability and their solid-state morphology being of the appropriate dimensions to efficiently perform charge collection and transfer to electrodes.

A jellified alginate based capsule serves as biocompatible and biodegradable electrolyte\ud system to gate an organic field-effect transistor fabricated on a flexible substrate.\ud Such a system allows operating thiophene based polymer transistors below\ud 0.5 V through an electrical double layer formed across an ion-permeable polymeric\ud electrolyte. Moreover, biological macro-molecules such as glucose-oxidase\ud and streptavidin can enter into the gating capsules that serve also as delivery system.\ud An enzymatic bio-reaction is shown to take place in the capsule and preliminary\ud results on the measurement of the electronic responses promise for low-cost,\ud low-power, flexible electronic bio-sensing applications using capsule-gated organic\ud field-effect transistor
