Abstract
The development of photovoltaic technologies have sparked significantly in last
three decades. The major factor being low cost, more reliability and high efficiency.
The simulation techniques used to minimize the size of devices are such as solar
cells and to reduce the time for research period. Solar cells are the promising
renewable resource that uses tri-valent and penta-valent compounds to achieve
energy conversions. In this study the most extensively investigated perovskite
methy-ammonium lead iodide (CH3NH3PBI3) is used as an active absorber layer
and and the impact of thickness and temperature on their performances will be the
main parameters to be studied. In this paper, SCAPS-1D will be used for the
simulation process in order to study the parameters such as open-circuit voltage
(Voc), short-circuit current (Jsc), Fill Factor (FF) % and Efficiency. This will be
done by varying the thickness and temperature. The thickness is being varied from
100nm to 700nm and temperature will be varried from 300K-500K. As the
thickness of CH3NH3PbI3 increases, decrease in open circuit voltage Voc, increase
in the short circuit current Jsc will be observed. Also the increase of the efficiency
and decrease of the Fill Factor (FF) will also be observed. Similarly, when the
temperature is being varied by keeping the thickness constant for 700nm change in
the parametric values will also be observed. As the temperature is increased there
is a sudden drop in the efficiency of the solar cell. Also the short circuit current
(Jsc), open circuit voltage (Voc) and Fill Factor (FF) decreased.
