The the disc so that there are

The production of electricity uses resources such as
coal, natural gas, nuclear energy and oil as technology spreads its roots and
is advancing at a rapid pace. To meet the demand of energy required alternate
sources are sought to be solar, wind, hydro and biomass.

Currently, 1.3% of the world’s energy is produced by
solar. The use of solar panels has doubled within the past three years which
show a significance rise in the use of solar panels. Although it is a green
solution, the efficiency of current solar cells is only 14% because most of the
photons are reflected off the solar panel rather than being absorbed which
defeats the purpose of solar panels.

Our experiment involves the use of solar panels and
Blu-ray disc. The disc which often fail to play over time are then thrown away
as trash. We came up with an idea to recycle the thrown Blu-ray disc. Place
them aligned to face the solar panel. 
Blu-ray disc can be used and any other because Blu-ray disc have a
higher density than other CD’s and DVD’s. The efficiency of the solar panels
will then increase due to a
quasi-random pattern simply a non-smooth surface (indentations on the discs
which are about 75nm), repeating every 150nm to 525nm found in the structure of
the Blu-ray discs which are almost perfectly tuned for trapping photons in the
visible light and near-infrared spectrum and that is why most of the Blu-ray
discs appear to have shiny surface which looks like a rainbow when observed
keenly. Error control codes have to be applied on the disc so that there are
small indentions on the disc which enables the reflecting of sunlight in
different angles. This method will increase the efficiency of the solar panel
by a massive 22%.

Other methods include using PV technology which only has an
efficiency of 14%, using thin film copper having an efficiency of about 20%.

In conclusion, this invention will increase the efficiency of
current solar panels which is only 14% to 36%. Therefore this will increase the
utilization of solar panels in Kenya and other countries around the globe due
to its higher efficiency of converting light energy from the sun into
electrical energy. This in turn will also help reduce the issue of global
warming and climate change due to less fossil fuels being burned for the production
of energy.
