“…Moreover, the nanostructured interpenetrating network in this solar cell device is constructed by electron donor (polymer) and electron acceptor materials (inorganic materials), enhancing the donor/acceptor interfacial area available for photogenerated exciton dissociated into charge carriers and enabling holes and electrons to be transported and collected, thus reduces the distance for the exciton that needs to travel before reaching an interface [4][5][6][7][8]. Charge photogeneration is therefore increased in this case [9][10][11]. However, the efficiency of these devices is still limited by the recombination of photogenerated hole-electron pairs at particle grain boundaries during charge transport across semiconductor particles [12][13][14].…”

“…Optical properties of such composites are obviously dependent on the several microstructural properties of these compounds, and; therefore, the determination of effective optical constants of mixtures in terms of the optical constants and volume fractions of the blend materials is useful [17]. Extensive studies have been undertaken to understand the electronic properties of P3HT:CdSe composite hybrid nanostructures, as these materials show great promise for optoelectronic applications [18,19]. However, little focus has been given on optical properties of the P3HT:CdSe bulk heterojunction materials.…”

The optical properties of nanocomposite layers prepared by incorporation of tributylphosphine oxide (TBPO)-capped CdSe nanocrystals (NCs) in a P3HT polymer matrix are studied using different nanocrystal concentrations. Reflection spectra analyzed through Kim oscillator model lead to the determination of optical constants such as refractive index n, extinction coefficient k, dielectric permittivity e and absorption coefficient a.Using the common Cauchy, Drude-Lorentz, Tauc and single-effective-oscillator theoretical models, we have determined the values of static refractive index n s and permittivity e s , plasma frequency x p , carrier density N, optical band gap E g and oscillator and dispersion energies E 0 and E d , respectively. It is found that TBPO-capped CdSe NCs concentration affects the optoelectronic parameters of the nanocomposite thin films. Moreover, the disorder of this hybrid system is also studied by the determination of Urbach energy, which increases with TBPO-capped CdSe concentration.

“…Many works on the synthesis of CP/NC nanocomposites have been reported [9,19,[24][25][26][27][28][29][30][31]. But some key chemicals, such as tri-n-octylphosphine oxide (TOPO) and trioctylphosphine (TOP), used in traditional routes are extremely toxic, expensive, explosive, and pyrophoric [7,11,12,28,31].…”

Carboxyl end-functionalized poly(3-hexylthiophene) (P3HT-COOH) was grafted chemically with CdSe nanocrystals (NCs) by a phosphine-free method. The particle quality of P3HT-COOH/CdSe nanocomposites was better than that of P3HT/CdSe nanocomposites, which were synthesized using the same method. Nanocrystals with controllable particle size exhibited a wurtzite crystalline structure and showed excellent nanocrystal dispersion in the P3HT-COOH matrix. Photoluminescence (PL) characterization performed on nanocomposites suggested the efficient charge transfer at the P3HT-COOH/CdSe interface. This approach based on the phosphine-free method is not only environmentally friendly but also highly efficient.
