The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation. The photovoltaic effect is closely related to the photoelectric effect, where electrons are emitted from a material that has absorbed light with a frequency above a material-dependent
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
The fundamental philosophy of improved PV cells is light trapping, wherein the surface of the cell absorbs incoming light in a semiconductor, improving absorption over several passes due to the layered surface structure of silica-based PV cells, reflecting sunlight from the silicon layer to the cell surfaces [36].

Flexible organic solar cells (OSCs) are very promising for use in portable power supply devices due to the advantages of low-cost, light-weight, and flexibility. However, the efficiencies of flexible OSCs are limited by the flexible transparent electrodes owing to their nonoptimal electrical, optical, and mechanical properties.

Organic solar cells use organic electronics and carbon-based materials as semiconductors to generate electricity from solar energy. They are also referred to as polymer solar cells or plastic solar cells. Although they follow the same process as traditional silicon solar panels for generic electricity, there is one significant difference between the two. Unlike silicon

Solar energy conversion originated from Jan Ingenhousz''s hypothesis in 1779 (Magiels, 2007).Jan based this concept on Joseph Priestley''s cylinder created in 1771 which was inspired by photosynthesis, a process used to sustain life on earth for 3.5 billion years (Matthews, 2009).The first photovoltaic observation was conducted in 1839 by Becquerel through
