Embryonic improvements of solar photovoltaics

Direct normal irradiance (DNI), ambient temperature, latitude effect, wind
velocity, air quality, etc. are various external-natural factors that influence efficiency of
solar photovoltaics (SPV), whereas materials used, technology adopted, etc. are
important internal design parameters that enhance efficiency of SPV. The recent
development in the field of materials engineering and technology may create a revolution
in the field of SPV if harnessed techno-economically. In the back drop of these
developments, this article dwells upon the material issues like aluminium (Al) nano
particles, birefringent liquid crystal polymer homeotropic films, and technological
issues like utilisation of acoustic vibrations using piezo-electric material, radiative
recombination, generation of pulses using pyroelectric materials, etc. to enhance
efficiency and the effectiveness of SPV. The article is followed by suggestions and
possible applications in real life situations and concluding lines. The article is just a
humble attempt from the academic point of view in the field of SPV.
