Abstract-Inorganic semiconductor AgInS 2 nanoparticles and P3HT/AgInS 2 composite was synthesized by decomposition of silver indium xanthate. The synthesized nanoparticles and composite were characterized by XRD and UV-Vis spectroscopy. PL quenching of the composite demonstrate that the electron transfer from polymer to inorganic NPs through ex-situ solution blending is less efficient in PL quenching as compared to in-situ synthesis.

“…Hybrid materials can overcome the traditional limits associated with the individual building blocks, as seen in applications in optics, 1 electronics, 2 biosensors, 3 and photovoltaics. 4 For example, dye-sensitized solar cells (DSSCs) 5 combine a stable titania photoanode that has excellent transport properties with synthetically tunable organometallic complexes. This combination addresses the relatively low electron mobility in molecular systems and the transparency of titania to visible light.…”

Designing Transmitter Ligands That Mediate Energy Transfer between Semiconductor Nanocrystals and Molecules

Molecular control of energy transfer is an attractive proposition because it allows chemists to synthetically tweak various kinetic and thermodynamic factors. In this Perspective, we examine energy transfer between semiconductor nanocrystals (NCs) and π-conjugated molecules, focusing on the transmitter ligand at the organic−inorganic interface. Efficient transfer of triplet excitons across this interface allows photons to be directed for effective use of the entire solar spectrum. For example, a photon upconversion system composed of semiconductor NCs as sensitizers, bound organic ligands as transmitters, and molecular annihilators has the advantage of large, tunable absorption cross sections across the visible and near-infrared wavelengths. This may allow the near-infrared photons to be harnessed for photovoltaics and photocatalysis. Here we summarize the progress in this recently reported hybrid upconversion platform and point out the challenges. Since triplet energy transfer (TET) from NC donors to molecular transmitters is one of the bottlenecks, emphasis is on the design of transmitters in terms of molecular energetics, photophysics, binding affinity, stability, and energy offsets with respect to the NC donor. Increasing the efficiency of TET in this hybrid platform will increase both the up-and down-conversion quantum yields, potentially exceeding the Shockley−Queisser limit for photovoltaics and photocatalysis.

“…The efficiency of exciton diffusion, which causes the generation of charge carriers in the PEDOT:PSS regions, is closely related to exciton diffusion lengths (LD) [14]. The LD is usually a value of less than 20 nm for conjugated conducting polymers [14,15]. From the value of the LD, the PEDOT:PSS coverage fabricated at 7500 rpm enable the efficient generation of charge carriers owing to the favorable exciton diffusion.…”

Silicon (Si)/organic polymer hybrid solar cells have great potential for becoming cost-effective and efficient energy-harvesting devices. We report herein on the effects of polymer coverage and the rear electrode on the device performance of Si/poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) hybrid solar cells with micro-pyramidal structures. These hybrid solar cells provided adequate generation of charge carriers owing to the suppression of reflectance to below 13%. Additionally, the separation of the photogenerated charge carriers at the micro-pyramidal-structured Si/PEDOT:PSS interface regions and their collection at the electrodes were dramatically improved by tuning the adhesion areas of the PEDOT:PSS layer and the rear electrode materials, thereby attaining a power conversion efficiency of 8.25%. These findings suggest that it is important to control the PEDOT:PSS coverage and to optimize the rear electrode materials in order to achieve highly efficient separation of the charge carriers and their effective collection in micro-textured hybrid solar cells.
