TL;DR: In this article, a photo-voltaic cell based on molecular light absorbers and mesoporous electrodes was developed, and the certified overall power conversion efficiency of the new solar cell for standard air mass 1.5 solar radiation stands presently between 10 and 11.
Abstract: Learning from the concepts used by green plants, we have developed a photo- voltaic cell based on molecular light absorbers and mesoporous electrodes. The sensitized nanocrystalline injection solar cell employs organic dyes or transition-metal complexes for spectral sensitization of oxide semiconductors, such as TiO 2, ZnO, SnO2, and Nb2O5. Mesoporous films of these materials are contacted with redox electrolytes, amorphous organ- ic hole conductors, or conducting polymers, as well as inorganic semiconductors. Light har- vesting occurs efficiently over the whole visible and near-IR range due to the very large inter- nal surface area of the films. Judicious molecular engineering allows the photoinduced charge separation to occur quantitatively within femtoseconds. The certified overall power conversion efficiency of the new solar cell for standard air mass 1.5 solar radiation stands presently between 10 and 11. The lecture will highlight recent progress in the development of solar cells for practical use. Advancement in the understanding of the factors that govern photovoltaic performance, as well as improvement of cell components to increase further its conversion efficiency will be discussed.

TL;DR: In this paper, a flexible PEDOT:PSS (poly(3,4 ethylenedioxithiophene):poly(styrenesulfonate)(PEDOT):PSS) organic films were used for wearable electronics.
Abstract: Searching an effective method to enhance the thermoelectric properties of flexible organic films can significantly widen the application of flexible thermoelectric devices. Tuning the microstacking structure and oxidation level can effectively optimize the thermoelectric properties of poly(3,4 ethylenedioxithiophene):poly(styrenesulfonate)(PEDOT:PSS) organic films. Here, we adopt triple post-treatments with formamide (CH3NO), concentrated sulfuric acid (H2SO4), and sodium borohydride in sequence to engineer flexible PEDOT:PSS thermoelectric films. A high power factor of 141 μWm−1 K−2 at 25 °C has been obtained for the PEDOT:PSS film. Such a high power factor stems from the high σ (1786 Scm−1) and S (28.1 μVK−1) after posttreatment with CH3NO, H2SO4, and NaBH4 in order. The increased carrier mobility resulting from both the selective removal of excess insulating PSS within the films and the conformation transition after CH3NO and H2SO4 treatments is responsible for the enhancement of σ, while the subsequent NaBH4 treatment optimize the electrical properties (σ and S) by modulating the oxidation level. A homemade thermoelectric device has also been fabricated using the as-prepared flexible PEDOT:PSS films and had a high output power density of ∼1 μWcm−2 with human arm as a heating source. This study indicates that flexible thermoelectric devices based on cheap conducting polymers have great potential in wearable electronics.

TL;DR: The electrical properties of template-synthesized three- and four-component rodlike nanostructures consisting of metal and conducting polymer domains have been studied and it is shown that these structures behave like nanometer-scale resistors and diodes, depending upon their compositions and spatial distribution.
Abstract: The electrical properties of template-synthesized three- and four-component rodlike nanostructures consisting of metal and conducting polymer domains have been studied. These structures behave like nanometer-scale resistors and diodes, depending upon their compositions and spatial distribution of the different compositional blocks. In the two-component systems, the conducting polymer block dictates the electrical properties of the nanostructure, and the metal blocks act as leads to facilitate the connection with microscopic circuits. In the three-component systems, the metal blocks provide an additional design flexibility, allowing one to prepare Schottky junctions.

TL;DR: In this paper, the authors employ porous filtration membranes as templates to entrap and align particles along the long axis of the pores, and then link them by 1,6-hexanedithiol to make shorter linear nanoparticle arrays (e.g., (Au particle)n, n ≤ 5).
Abstract: New strategies are reported for assembling Au nanoparticles into coupled 1D arrays. The mehods employ porous filtration membranes as templates to entrap and align particles along the long axis of the pores. Following alignment, nanoparticles were linked by 1,6-hexanedithiol to make shorter linear nanoparticle arrays (e.g., (Au particle)n, n ≤ 5) or with the organic conductive polymer polypyrrole to make longer 1D arrays. These methods provide new opportunities for characterizing the electronic and optical properties of coupled nanoscopic solid-state materials.
