In this study, an acidic (A) and pH-neutral (pHN) solution using poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) as the hole-transport layer (HTL) was modified a 1-butyl-3-methylimidazolium chloride (BMIM+Cl−) ionic liquid (IL). The effects of on conductivity morphological properties PEDOT:PSS films were investigated. PEDOT: PSS before after adding IL measured UV–vis spectrophotometer atomic force microscope (AFM), respectively. A-PEDOT:PSS-film-based decreased, while...
Semiconducting, octadecylamine (ODA)-capped, rod-like FeS2 nanocrystals (NCs) are prepared and their properties characterized. Transmission electron microscopy studies revealed the lattice fringes were clearly visible, confirming that NCs obtained in this study highly crystalline. X-ray diffraction (XRD) indicated structure of is cubic phase. Optical showed can be a promising candidate for acceptor material bulk hetero-junction (BHJ) solar cell applications. The power conversion efficiency...
Conventional vacuum deposition process of aluminum (Al) is costly, time-consuming and difficult to apply the large-scale production organic photovoltaic devices (OPV). This paper reports a vacuum-free fabrication poly[[4,8-bis(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thienophenediyl]:[6,6]-phenyl C71 butyric acid methyl ester (PTB7:PCBM) bulk heterojunction solar cell with liquid eutectic gallium–indium (EGaIn) electrode as an alternative...
Bulk heterojunction solar cells were fabricated by blending semiconducting cadmium selenide nanoparticles with various capping ligands and regioregular poly(3-hexylthiophene). The effects of surface ligand modification CdSe thermal treatment on the device performance investigated. It was found that could affect increasing charge carrier separation at nanoparticle/polymer interface quenching photoluminescence. Thermal cell structure 140 °C to be optimal for performance, resulting in a maximum...

Cu-In-Ga-Se nanoparticles (NPs) were synthesized using a colloidal route process. The effects of growth temperature (GT) on the properties CuInGaSe2 (CIGS) thin films made from these investigated TEM, PL, XRD, and SEM techniques. NPs at temperatures ranging 90 °C to 105 then annealed 550 for 7 min under Se ambient. resulting CIGS film, formed GT (referred as GT90-CIGS), showed tetragonal structure, large grain size, high sunlight absorption. It had band gap energy (Eg) approximately 0.94 eV....
In this paper, zinc oxide (ZnO) nanorods (Nrods)–polymer based bulk hetero-junction solar cells were fabricated employing an eutectic gallium–indium (EGaIn) alloy negative electrode coated using a brush-painting method.
