Enhanced photovoltaic effects of microwave-assisted polyolsynthesized Cu2(Pd/Zn)SnS4 kesterite nanoparticles
Nwambaekwe, Kelechi C.; Ramoroka, Morongwa E.; Iwuoha, Emmanuel I. (Elsevier, 2023)Kesterite materials show excellent optical and semiconductive properties for use as petype absorber layer in photovoltaic (PV) applications, but they have a high open circuit voltage deficit (Voc,def) due to high antisite ... -
Fabrication, characterization, and photovoltaic performance of titanium dioxide/metal-organic framework composite
Ramaripa, Phuti S.; Modibane, Kwena D.; Ramoroka, Morongwa E. (Elsevier, 2022)The titanium dioxide-metal-organic framework (TiO2−MOF) composite was prepared using the sol-gel method for photovoltaic applications. Raman analyses showed the presence of MOF clusters in the TiO2 sol-gel network. Using ... -
Synthesis and reactivities of conducting hexathienylbenzene-co-poly(3-hexylthiophene) star-branched copolymer as donor material for organic photovoltaic cell
Ramoroka, Morongwa E.; Mdluli, Siyabonga B.; John-Denk, Vivian S. (Frontiers Media, 2022)The hexathienylbenzene-co-poly(3-hexylthiophene-2,5diyl) (HTB-co-P3HT) conducting polymer was synthesized by oxidative co-polymerization of hexathienylbenzene (HTB) and 3-hexylthiophene using iron chloride (FeCl3) as an ...
