“…Anyway, in this case PCEs of only 0.04% were obtained [125]. P3HT/Bi 2 S 3 hybrid solar cells, which were also prepared according to the described procedure, exhibited very low V OC , which led to an efficiency of 0.005% [127]. However, the material combination P3HT/Ag 2 S highlights the potential of this approach and enhancement of the efficiencies can be expected by further optimization in the near future.…”

Hybrid solar cells based on conjugated polymers and inorganic semiconducting nanoparticles combine beneficial properties of organic and inorganic semiconductors and are, therefore, an exciting alternative to pure organic or inorganic solar cell technologies. Several approaches for the fabrication of hybrid solar cells are already elaborated and explored. In the last years routes have emerged, where the nanoparticles are prepared directly in the matrix of the conjugated polymer. Here, the conjugated polymer prevents the nanoparticles from excessive growth and thereby makes additional capping agents obsolete. This review focuses on in situ preparation methods of inorganic semiconducting nanoparticles in conjugated polymers in view of applications in hybrid solar cells. The details, advantages and disadvantages of the different in situ methods are critically examined and put in comparison to the classical route where pre-synthesized nanoparticles are used. Various key factors influencing the solar cell performance as well as future strategies for increasing the overall efficiency of hybrid solar cells prepared via in situ routes are discussed.

Doping is a technique that makes it possible to incorporate substitutional ions into the crystalline structure of materials, generating exciting properties. This book chapter will comment on the transition metals (TM) doped nanocrystals (NCs) and how doping and concentration influence applications and biocompatibility. In the NCs doped with TM, there is a strong interaction of sp-d exchange between the NCs’ charge carriers and the unpaired electrons of the MT, generating new and exciting properties. These doped NCs can be nanopowders or be embedded in glass matrices, depending on the application of interest. Therefore, we show the group results of synthesis, characterization, and applications of iron or copper-doped ZnO nanopowders and chromium-doped Bi2S3, nickel-doped ZnTe, and manganese-doped CdTe quantum dots in the glass matrices.

“…12 In further approaches, the polymer matrix was polymerised in the presence of Bi 2 S 3 nanoparticles, 26 or pre-formed nanostructured Bi 2 S 3 layers were coated with a polymer. 27 All these approaches are rather tedious and require several steps. In contrast, in this work we discuss a convenient and fast route to prepare metal sulphide-polymer nanocomposites by synthesising Bi 2 S 3 nanocrystals directly within a polymer matrix in the solid state without the necessity of a separate nanoparticle synthesis step.…”

Bismuth sulphide–polymer nanocomposites from a highly soluble bismuth xanthate precursor

Bismuth sulphide nanocrystal-polymer hybrid layers are of interest for various optoelectronic, thermoelectric or sensing applications. In this work, we present a ligand-free in situ route for the formation of Bi 2 S 3 nanorods directly within a polymer matrix. For this purpose, we introduce a novel bismuth xanthate (bismuth(III) O-3,3-dimethylbutan-2-yl dithiocarbonate), which is highly soluble in nonpolar organic solvents. The analysis of the crystal structure revealed that the prepared bismuth xanthate crystallises in the monoclinic space group C2/c and forms dimers. The bismuth xanthate can be converted into nanocrystalline Bi 2 S 3 with an orthorhombic crystal structure via a thermally induced solid state reaction at moderate temperatures below 200 C. In combination with the high solubility in nonpolar solvents this synthetic route for Bi 2 S 3 is of particular interest for the preparation of Bi 2 S 3-polymer nanocomposites as exemplarily investigated on Bi 2 S 3-poly(methyl methacrylate) and Bi 2 S 3poly(3-hexylthiophene-2,5-diyl) (P3HT) nanocomposite layers. Atomic force and transmission electron microscopy revealed that Bi 2 S 3 nanorods are dispersed in the polymer matrix. Photoluminescence experiments showed a quenching of the P3HT fluorescence with increasing Bi 2 S 3 content in the hybrid layer.
