The sun''s energy is getting considerable interest due to its numerous advantages. Photovoltaic cells or so-called solar cell is the heart of solar energy conversion to electrical energy (Kabir et al. 2018). Without any involvement in the thermal process, the photovoltaic cell can transform solar energy directly into electrical energy.
In order to increase the worldwide installed PV capacity, solar photovoltaic systems must become more efficient, reliable, cost-competitive and responsive to the current demands of the market.
