    OPTIMIZING THE EFFICIENCY OF PEROVSKITE SOLAR CELL BY INCREASING THICKNESS AND TEMPERATURE
    (DEPARTMENT OF PHYSICS KINNAIRD COLLEGE FOR WOMEN UNIVERSITY LAHORE,, 2023-05-17) ZAINAB FATIMA
    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.
