“…[10][11][12] The use of Fe in photovoltaics (PV) was proposed nearly 25 years ago in the FeS 2 pyrite form, but the low photovoltage, sulfur deficiencies and poor structure uniformity has limited their PV applications. [15][16][17][18][19][20][21][22] The properties of colloidal semiconducting nanocrystals are strongly associated with their composition, shape, phase and size. 14 Recent studies have revealed that solution processed colloidal nanocrystals have an overwhelming influence on the cost efficiency of PV cells, compared to their bulk counterparts.…”

The large absorption coefficient of iron pyrite (FeS(2)) nanocrystals coupled with their low-cost and vast-abundance shows great promise as a potential photovoltaic absorber. Here, we demonstrate that bulk heterojunction (BHJ) nanostructures consisting of 80 nm FeS(2) nanocubes (NCs) and 4 nm CdS quantum dot (QD) matrix, lead to a well-defined percolation network, which significantly improved open-circuit voltage (V(oc)) to 0.79 V and power conversion efficiency of 1.1% under AM 1.5 solar illumination. The localized surface plasmon resonances (LSPRs) arising from p-type colloidal FeS(2) NCs exhibit plasmonic photoelectron conversion. Our approach can be applied to a wide range of colloidal nanocrystals exhibiting the LSPRs effect and is compatible with solution processing, thereby offering a general tactic to enhancing the efficiency of all inorganic BHJ solar cells and LSPRs-based NIR photodetectors.

“…Similar to organic solar cells, [35][36][37][38][39][40] two main morphologies of the active layers are found in literature, a planar and a bulk heterojunction (BHJ) geometry. [41][42][43][44][45][46][47] In a planar arrangement, the n-type and p-type materials have one more or less planar interface. In Principle processes occurring in hybrid solar cells.…”

In hybrid photovoltaics, an organic and an inorganic semiconductor are combined in the active layer, with the advantages of both material classes in a single device. The organic component contributes towards the possibility for wet chemical device preparation with potentially low costs in combination with achieving flexible devices. From the inorganic component an increase in stability, as well as superior opto‐electronic properties, is added. Given the large diversity of organic and inorganic semiconductors, a large number of possible realizations of hybrid solar cells emerge. In the present review, we limit to hybrid solar cells which combine conjugated polymers with inorganic materials such as titanium dioxide, zinc oxide, silicon, germanium and quantum dots to keep focused. Particular emphasis is put on different routes to tailor nanostructures, such as the use of semiconductor block copolymers. The inorganic component is either synthesized directly in one of the blocks or added as a pre‐synthesized nanomaterial to form the hybrid material. Alternatively, the block copolymer is used as a structure‐directing template in a sol–gel synthesis approach to have tailored inorganic nanostructures, which are back‐filled with the organic component to fabricate the hybrid material. Hybrid solar cells based on crystalline Si are discussed for comparison.

“…The CdSe NRs were thereafter functionalized with rr‐P3HT via Pd‐catalyzed Heck coupling . In the same year, Lin and co‐workers converted the BBPA functionalized CdSe NRs into azide‐benzylphosphonic acid (N 3 ‐BPA) capped NRs, thus making them eligible for catalyst‐free click reaction . N 3 ‐BPA capped NRs reacted with ethynyl‐functionalized P3HT resulting in 1,2,3‐triazole ring formation (see Figure ).…”

Simple blends of inorganic nanocrystals and organic (semiconducting) polymers usually lead to macroscopic segregation. Thus, such blends typically exhibit inferior properties than expected. To overcome the problem of segregation, polymer coated nanocrystals (nanocomposites) have been developed. Such nanocomposites are highly miscible within the polymer matrix. In this Review, a summary of synthetic approaches to achieve stable nanocomposites in a semiconducting polymer matrix is presented. Furthermore, a theoretical background as well as an overview concerning morphology control of inorganic NCs in polymer matrices are provided. In addition, the morphologic behavior of highly anisotropic nanoparticles (i.e. liquid crystalline phase formation of nanorod-composites) and branched nanoparticles (spatial orientation of tetrapods) is described. Finally, the morphology requirements for the application of inorganic/organic hybrid systems in light emitting diodes and solar cells are discussed, and potential solutions to achieve the required morphologies are provided.
