Abstract
Thin film solar cells with polycrystalline silicon absorber layers are one of the
most promising approaches to realizing both high performance and low cost for
efficient solar cell technology in the near future. The main goal of this research is to
fabricate a flexible polycrystalline silicon thin film solar cell having thicknesses of
1.61 μm to 13.10 μm using the screen printing (SP) technique onto a polyethylene
terephthalate (PET) sheet as (A) substrate and (B) superstrate. The PET used has
high optical transmittance (93%) in UV-Visible range, a crystallite size of 34.64 nm,
with thermal sustainability and a melting point of 254.9 °C. Indium tin oxide (ITO)
thin films were deposited on the PET by DC magnetron sputtering and thermal
evaporation at thicknesses of 25.0, 87.2 and 114.5 nm and 36.0, 79.2 and 124.5 nm,
respectively. The PET substrate coated ITO with thickness of 25.0 nm, optical
transmittance of 97% in UV-visible range and surface roughness of 2.32 nm by DC
magnetron sputtering, was found suitable for this current work.
