Photovoltaic Properties of Solar Cells Based on Poly(methyl phenyl silane) and C₆₀

Abstract

Photovoltaic (PV) devices using blend films of poly(methyl phenyl silane) (PMPS) and fullerene (C60) are fabricated, and the effects of various technical parameters during device fabrication on the PV characteristics under AM 1.5G simulated solar light illumination of 100 mW/cm2 intensity are investigated. The PV performance of the devices depends on the mixing ratio of PMPS:C60, the kind of buffer layer, the thickness of the buffer layer, and the thermal annealing temperature of the devices. The devices optimized for the mixing ratio, kind of buffer layer, and thermal annealing temperature exhibit a short-circuit current density (J SC) of 2.26 mA/cm2, an open circuit voltage (V OC) of 0.71 V, a fill factor (FF) of 0.35, and a power conversion efficiency (PCE) of 0.57%.

Refractive Properties of Conjugated Organic Materials Doped with Fullerenes and Other Carbon-Based Nano-Objects

“…However, with the extensive use of laser tools in the study of the characteristics of inorganic and organic materials, particularly the refractive properties of the features of nanostructured materials [2][3][4][5][6][7][8], which are undeniably connected to their spectral and photoconductive properties, these studies began to occupy a special research focus. Moreover, due to the effective use of the fullerenes and other nano-objects [9][10][11][12][13][14][15][16][17][18][19][20] in material parameter modifications, the sensitization (doping) process was established as the dominant method. Furthermore, this technique can be easily tested and visualized, permitting a good opportunity for effective analytical analysis.…”

“…Furthermore, this technique can be easily tested and visualized, permitting a good opportunity for effective analytical analysis. Thus, the photoinduced electron transfer in the conducting-polymer-C 60 composites was evaluated using infrared photoexcitation spectroscopy [9]; the photoinduced electron transfer in the C 60 -doped poly(N-vinylcarbazole) films was revealed by picosecond laser photolysis in [12]; the significant effect of fullerene doping on the absorption edge shift was determined for the 2cyclooctylamino-5-nitropyridine nanocomposite in [15]; refractive grating was recorded in Polymers 2023, 15, 2819 2 of 14 the fullerene-doped liquid crystal materials in [5,11,16]; a high conducting polyaniline complex was synthesized with fullerene C 60 in [14]; and the improvement of the photovoltaic properties of the solar cells, based on the poly(methyl phenyl silane)-C 60 nanocomposites, was shown in [19].…”
