“…It is found that a hybrid containing 80 wt% CdSe NTs could intensively quench the PL intensity of P3HT NWs, especially the main emission at 700 nm. This is interestingly the same with that of the organic polymer-grafted nanoparticles reported in ref [30]. The static PL result indicates that the photon-generated excitons could be efficiently dissociated through diffusing in the crystallized P3HT NWs and thereafter splitting at the hybrid interface.…”

Constructing a highly efficient bulk-heterojunction is of critical importance to the hybrid organic/inorganic solar cells. Here in this work, we introduce a novel hybrid architecture containing P3HT nanowire and CdSe nanotetrapod as bicontinuous charge channels for holes and electrons, respectively. Compared to the traditionally applied P3HT molecules, the well crystallized P3HT nanowires qualify an enhanced light absorption at the long wavelength as well as strengthened charge carrier transport in the hybrid active layer. Accordingly, based on efficient dissociation of photogenerated excitons, the interpercolation of these two nano-building blocks allows a photovoltaic conversion efficiency of 1.7% in the hybrid solar cell, up to 42% enhancement compared to the reference solar cell with traditional P3HT molecules as electron donor. Our work provides a promising hybrid structure for efficient organic/inorganic bulk-heterojunction solar cells.

“…Several capping strategies have emerged in the literature: the ligand exchange [15][16][17], the use of novel surfactants [18,19], the synthesis of NPs with thermally cleavable ligands [20], the synthesis of NPs in solutions of polymers [21,22], the polymerization of polymers on the surface of NPs [23], and the deposition of a polymer containing a soluble precursor of the NPs [24]. More details on the role of capping ligands/polymers can be found in recent works [25][26][27][28][29].…”

“…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.
