The Use Of Polymers
Ever since the first polymer was fabricated in 1907, scientists have been seeking
new applications for classic polymers (Brewer, 2006). Recently, in 2010, an
enhanced structure of the photovoltaic cell (PVC) was proposed: synthesising new
polymers from regular polymers for advanced donating and electron accepting (D
A) moieties in PVCs (Mike et al., 2010). Also, in 2005, another additional
application for traditional polymers has been discovered. By adding cinnamic acid
to a flexible polymer, a material is produced which changes shape in response to
different wavelengths of ultraviolet (UV) light (Lendlein, 2005). Hence, an old
polymer can be taught new applications and tricks if modified in some way.

Likewise, polybenzobisoxazoles (PBBO)s, found in zylon, are multifunctional
materials commonly applied in electrical structures for their high tensile strength,
thermal stability, efficient electron transport, and high electron affinity (Intemann
et al., 2011). So, when the thiophene and benzobisoxazoles (BBO)s from these
compounds are combined with other molecules such as aldehydes, and two new
polymers, namely poly[(3,4 didodecylthiopene vinylene) alt benzo[1,2 d;5,4 d ]
bisoxazole] 2,6 diyl (PTVcBBO) and poly[(3,4 didodecylthiopene vinylene) alt
benzo[1,2 d;4,5 d ]bisoxazole] 2,6 diyl (PTVtBBO) are formed, D A moieties with
a low band gap and high electron transfer are produced (Kim et al., 2015). These
moieties are then used to enhance PVC efficiency and electron transfer. Firstly, the
direct conversion of sunlight into energy using PVCs has been recognised as an
imperative component of future global energy production. As a result of their optical
and electrical properties, conjugated organic materials are being suggested to replace
inorganic materials in PVCs due to their ability to manipulate their electron properties
through chemical synthesis (Mike et al., 2010). So, to improve the electrical
properties of regular PVCs, the band gap (the energy difference between the top of
the valence band and the bottom of the conduction band) must be lowered
