Metal additive processing in polymer: fullerene bulk heterojunction systems is recognized as a viable way for improving polymer photovoltage performance. In this study, the effect of niobium (Nb) metal nanoparticles at concentrations of 2, 4, 6, and 8 mg/mL on poly(3-hexylthiophene-2,5-diyl) (P3HT)-6,6]-phenyl C61-butyric acid methyl ester (PCBM) blends was analyzed. The effect of Nb volume concentration on polymer crystallinity, optical properties, and surface structure of P3HT and PCBM, as well as the enhancement of the performance of P3HT:PC61BM solar cells, are investigated. Absorption of the P3HT:PC61BM mix is seen to have a high intensity and a red shift at 500 nm. The reduction in PL intensity with increasing Nb doping concentrations indicates an increase in PL quenching, suggesting that the domain size of P3HT or conjugation length increases. With a high Nb concentration, crystallinity, material composition, surface roughness, and phase separation are enhanced. Nb enhances PCBM’s solubility in P3HT and decreases the size of amorphous P3HT domains. Based on the J–V characteristics and the optoelectronic study of the thin films, the improvement results from a decreased recombination current, changes in morphology and crystallinity, and an increase in the effective exciton lifespan. At high doping concentrations of Nb nanoparticles, the development of the short-circuit current (JSC) is associated with alterations in the crystalline structure of P3HT. The highest-performing glass/ITO/PEDOT:PSS/P3HT:PCBM:Nb/MoO3/Au structures have short-circuit current densities (JSC) of 16.86 mA/cm2, open-circuit voltages (VOC) of 466 mV, fill factors (FF) of 65.73%, and power conversion efficiency (µ) of 5.16%.

The main purpose of this experimental research is to study the effects of different silver concentrations on the optical properties of bimetallic Agshell/Aucore nanoparticles. The gold nanoparticles are ablated by the PLAL technique of the gold target on the bottom of the container. The container is filled with colloidal silver nanoparticles and manufactured by chemical reduction. The colloidal solution of mixed nanoparticles is irradiated by the second harmonic of the pulsed laser Nd:YAG laser at 532 nm wavelength. The peak absorption of gold nanoparticles around 530 nm is used to transfer laser energy to nanoparticles and synthesis the Agshell/Aucore bimetallic nanoparticles. The volumetric ratio of nanoparticle solutions are the experimental variables. Bimetallic nanoparticles are distinguished by the following: X-ray diffraction pattern (XRD), spectroscopy in the range of UV-Vis-NIR and IR, Dynamic light scattering (DLS), Energy Dispersive Spectroscopy (EDS), Photoluminescence spectrum (PL) and, Fourier transform infrared spectroscopy (FT-IR). In addition, FE-SEM and TEM images are used to investigate nanoparticle size and morphology. One of the objectives of this research is the preparation of stable bimetallic systems and the study of optical properties, in order to check the reactivity of silver nanoparticles in the bimetallic system. Moreover, the shell thickness and catalytic properties of bimetallic structure with a different silver concentration is discussed. The following, dipole mode is shown in the visible area for every samples and quadrupole mode is not detected in sample with high silver concentration.

Herein, the electrical conductivity of poly(3,4‐ethylenedioxythiophene)–poly(styrenesulfonate) (PEDOT:PSS) polymer is improved by adding dimethyl sulfoxide (DMSO) and electrical characterization of the obtained Schottky diode and organic solar cell (OSC) devices are performed from I–V measurements under the light and dark conditions. The scanning electron microscope images of the poly(3‐hexylthiophene):[6,6]‐phenylC61‐butyric acid methylester active layer and PEDOT:PSS layer are obtained. The series resistance (Rs), barrier height (Фb), and ideality factor (n) parameters are obtained from different techniques as a function of light and dark conditions. Furthermore, photovoltaic parameters are calculated for n‐Si/PEDOT:PSS/Au device without DMSO doping and with DMSO doping as a parameter of the light condition and the interface state densities of these devices are obtained for light and dark conditions. DMSO organic solvent improves the short‐circuit current density (Isc), power convert efficiency (or η), open circuit‐voltage (Voc), shunt resistance (Rsh), and series resistance (Rs) values of OSCs. In summary, DMSO solvent rearranges the conductive of PEDOT:PSS, decreases the work function of this conductive polymer (≈5 eV), decreases energy loss in the charge transportation, and increases photovoltaic parameters of Schottky barrier diode and OSC devices.
