The Institute of Laser for Postgraduate Studies discussed a Master’s thesis entitled “High Performance of Graphene/Cobalt Core Shell in Si Solar Cell” by Rusul Ahmed Majid.
The study aimed to develop and fabricate an ultra-thin silicon solar cell doped with graphene/cobalt core-shell nanoparticles, and to investigate its optical properties and electric field distribution under various factors, including nanoparticle size, number, and film thickness.
The results showed that the best performance was achieved by the ultra-thin silicon solar cell containing graphene/cobalt core-shell nanoparticles (4 particles, 30 nm radius, and 2 nm film thickness), which produced a photocurrent of 26.28 mA/cm².
The study concluded that the optical properties of the designed cells depend mainly on their structure and the doped nanoparticles, resulting in improved performance. The ultra-thin silicon solar cell doped with graphene/cobalt core-shell nanoparticles showed the highest performance due to the plasmonic effect, which may open new avenues for research in this field.
