SIMULATION OF ELECTRICAL PROPERTIES OF HETEROJUNCTION AND BILAYER ORGANIC SOLAR CELLS USING 'OGHMANANO' SOFTWARE
Keywords:
organic solar cells, heterojunction, bilayer, fill factor, power conversion efficiencyAbstract
This paper presents a comparison between heterojunction organic solar cells (HOSCs) and
bilayer organic solar cells (BOSCs) in terms of the simulation of the fill factor (FF) and the power
conversion efficiency (PCE). HOSCs are a competitive alternative source of electrical energy.
BOSCs have gained a lot of interest because they are known to be environmentally friendly.
Currently, the construction of the organic solar cells is motivated by the need for optimising the
perfect material to generate greater electrical energy. Thus, the organic solar cell structures
design and certain materials is of vital importance to develop and enhance the conversion
efficiency and fill factor of organic solar cells. The simulation tools are ‘OghmaNano’ the method
used in this study. HOSCs consist of the structure layer such as
ITO/ZnO/P3HT:PCBM/PEDOT:PSS/Au. BOSCs consist of the structure layer which is ITO/
PEDOT:PSS/P3HT/Al. Thus, BOSCs at 0.5 W/m 2 light intensity achieved a FF of 0.761608 % and
for the PCE realised 3.816099 % at 2.5 W/m 2 light intensity. HOSCs at 0.09 W/m 2 light intensity
achieved a FF of 0.688035 % and the PCE realised 4.961236 % at 0.4 W/m 2 light intensity.
