INTRODUCTION
Renewable energy is fast gaining momentum in the energy sector all over the world. Major
electricity producers are fast shifting focus on harvesting solar radiation to produce electricity. In
the recent past, the massive campaign has been launched to ensure that we have a sustainable
environment free from pollution that is caused by the combustion of fossil fuels to produce
energy or electricity. Thus making renewable energy sources the best alternative to replace non-
renewable or fossil fuels (Grant and HicksL., 2020). The scientist had described the sun as the
source energy that illuminates the earth and source of life to animals and plants since they
depend on sunlight either directly or indirectly for survival. However, the sun doesn't illuminate
the earth at night due to the principle of the earth's rotation. But most of the electrical appliances
require electricity all the time. Therefore mechanical engineers, in collaboration with electrical
engineers, started developing systems, appliances, infrastructures, and machines that would
ensure a continuous supply of solar energy even at night by developing inverters, solar batteries.
And the most recent is the use of Nano-technology to optimize the efficiency of solar cells to
harness maximum power from the sun during the day and store the harvested electricity for later
use (Ahmadi et al., 2019).
High demand and a keen interest in renewable energy have facilitated tremendous growth in the
solar cell industry. However, this high demand comes with a lot of pressure in the manufacturing
sector of the solar panels and its accessories, making mechanical engineers to work around the
clock to ensure that their products are the most sustainable and are of high efficiency (Bhushan,
2017). Solar cell manufacturing industry has faced a challenge over the past decade, the cost of
fabricating high energy rated solar panels and accessories is quite expensive and costly to

average daily radiation from the sun is about 1.7 × 1017 watts. This wattage is much more than
the earth's energy demands, therefore if even the smallest ratio of 1: 1000 of this capacity is
harnessed correctly through the use of appropriate technology would satisfactorily provide the
earth with renewable energy to meet its demands. There is dire need to improve on the solar

LITERATURE REVIEW
Over the past decade, the growth and tapping of renewable energy have registered positive
growth in the overall global energy consumption scale. This rise in use of renewable energy has
been dramatically affected by the United Nation's campaigns, environmental sustainability
policies, prediction of depletion of non-renewable energy source, uneven fossil energy
distribution, political initiatives, etc. having close consideration on the vital energy source
statistics, even though non-renewable fossil fuels takes the lead. Still, over the past decade, fossil
fuel dominance has become weak, with the adoption of renewable solar energy considered by
many for household appliances and electrical applications due to its reduced cost and other
related expense (Chen et al., 2019). A typical illustration of these statistics is evident in the
United States' annual energy production rate for nuclear, renewable energy, and nuclear energy
sources. When this data is plotted on a graph of production against years shows a shift to
renewable energy source as shown in the figure below (data obtained from united states annual
energy production in the past years and U.S. Energy Information Administration EIA).

Figure 2: Different energy demand from 1940 to 2010 (Salomé. and Sadewasser, 2019)
From the above figure, it's evident that fossil fuels are the dominant source energy used to power
most industries, with its usage almost doubling that of renewable energy (Roco, Mirkin, and
Hersam., 2015). Over the past fifty years, the use of renewable energy has been stalled by
challenges such as reliability and efficiency, thus making it not applicable to substantial
electricity consumption uses. According to EIA, the growth in renewable energy sources is
dominated by the application of P.V. solar panels in residential homes (Hong et al., 2020).
The overview of the previous energy production data proves that the relationship between
production rate and the growth rate is inversely proportional, showing that the use of 0of solar
power has been so rapid and attractive. The study considered about 20 journals and publications
relating to the use of nanotechnology in the development of solar panels. My understanding and
knowledge obtained in my undergraduate and master's level have facilitated the compilation of

The evolution of solar cells
The miniaturization of solar cells has evolved by time, with the latest evolution being the
developments of dye-sensitized solar cells (Javed et al. 2020). Solar cell evolution stages are
categorized into generations with 1st generation characterized by the use of conventional silicon
solar chips and wafers to formulate the reflective system. The silicon chips did not meet the
engineer's expectations; therefore, 2nd generation solar cells came into play.2nd generation phase
was associated with the use of amorphous silicon to make thin cells, the cells were flexible with
low production cost, but their efficiency was low. Thus, 3rd generation cells came into play. The

Advantages of nanotechnology in solar P.V. panels
When nanotechnology is mentioned, many think about the efficacy of improving solar panels.
Still, most importantly, nanotechnology can be used by mechanical engineers to reduce the
manufacturing and fabrication cost of the solar components. For example, the efficiency of dye-
sensitized solar cells has been improved by nanotechnology to about 20%, with its cost reduced
to almost half of its initial cost.
Through the use of nanotechnology in solar P.V. panels, over 12 million residential homes in
America are powered by solar energy just because nanotechnology has greatly improved the
solar cells efficiency and reliability
Nanotechnology in the manufacture of solar cells has aided and promoted the most hyped
campaign towards having a clean and sustainable environment free from fossil fuels since it has
provided the perfect alternative for fossil fuels in domestic applications and household
appliances
Solar cells made through nanotechnology are tiny hence light in weight and occupy small space.
Solar panels developed through nanotechnology are flexible. Therefore, they can be folded to
ease packaging and transportation even to remote areas.
Nanotechnology provides a solution to solar panel by proving probably hundreds of nanometers
that creates a layer of interface between the nanostructures and the air, and this prevents the
unnecessary reflection of sunlight to other places rather than the solar cells that does the
conversion

These nanoparticles can be used in the manufacture of nano-cells with thin films to reduce
radiation absorption, and loss before conversion to electric energy takes place.

extremely thin-film of silicon solar cells remains in the absorption and conversion unit of P.V.
solar cells. The method of nano silicon manufacturing is quite simple and does not require many
funds but instead produces improved solar efficiency (Abrusci et al. 2018). Nano silicon
technique does not only produce thin-film solar cells of about 3 to 11 nanometer (Salomé. and

RESULTS AND DISCUSSION
The use of nanoporous flexible layer germanium and nanotechnology in the manufacture of solar
cells helps in producing improved solar efficiency at a lower cost. This addressed the challenge
currently faced by industries and domestic solar users that the cost of installation is quite high,
and purchasing capital is also high compared to the cost of acquiring fossil fuels. The inflated
cost of the solar panel system is often caused by the high cost of materials used in making solar
cells and solar panels as a whole. Application of nanotechnology in the development of thin-film
solar cells will help in reducing the purchase and installation cost of solar panels and ta the same
time produce ample wattage that can run industries thus completely substituting fossil fuels as a
source of power in industries
