Photovoltaic or PV systems are one of the next
generation’s renewable energy sources for our world
energy demand. It’s a method of generating electrical
power by converting solar radiation into direct current
electricity. When light shines on a PV cell, it may be
reflected, absorbed, or pass right through. But only the
absorbed light generates electricity. An electrical field is
created near the top surface of the cell where these two
materials are in contact. The PV system affected highly by
the dust and pollutants accumulation on its surface as it
reduces the solar light reaches the cell; as a result reduce
the cell outcome.
In this experimental work, three types of Iraqi construction
materials (cement, plaster, and borax) were used as
pollutants to evaluate their effect on the PV cell
performance. The results reveal that borax has the lowest
impact on the cell current while plaster has the maximum
level. The output power and efficiency were influenced by
these impacts and plaster ranked the minimum efficiency
with about 25.8% reduction compared to clean cell.
