Using of Nanotechnology for Photovoltaic Solar Energy Systems

NanoEra, cilt.1, sa.2, ss.39-44, 2021 (Hakemli Dergi)

It is very important to obtain energy from renewable energy sources at this time when

energy consumption is increasing rapidly and environmental pollution has reached

significant dimensions. Solar ener

gy is one of these sources. Recently used photovoltaic

systems are very important in the supply of electrical energy. The low efficiency of

photovoltaic panels used to generate electricity is one of the most important disadvantages

of these systems. The ef

ficiency of photovoltaic cells is greatly affected by both the

materials used to convert the incoming solar energy into electrical energy and the surface

pollution. The use of nanomaterials has recently increased considerably to increase

efficiency. Studie

s are carried out on self

cleaning materials in order to reduce the

reflection of incoming rays and to ensure that the energy is selectively absorbed by the

surface and prevent surface pollution. Nanotechnology makes very important contributions

to the des

ign and production of thin

film PV cells. PV cells developed using nanomaterials

will continue to reduce the cost of commercial solar cells using cheaper raw materials.

Nanomaterials have some desirable properties such as high catalytic activity, better st

ability

in aqueous media, relatively easier preparation techniques, and material economy. In this

study, information is given about nanomaterials used in photovoltaic cells and efficiency

enhancing studies in PV technology
