This work presents the construction and testing of solar cells sensitized with natural
dyes extracted from plants indigenous to the desert.
Calotropis
plants are self
-
sufficient as they
grow in very harsh environments, and yet are not consumed by humans or livestock due to their
irritating agents to the skin and eyes. The energy generators of these plants are the leaves, which
are crushed and processed
to produce the dye solution. Also, the
Calotropis
leaves are covered in
a white powder that is thought to aid in mitigating the heat by scattering incident radiation. This
powder material is examined and added to the dye as it proved advantageous for the o
verall cell
efficiency, which reached 0.214% compared with 0.108% for cells with no powder. The produced
cells are also compared with ones sensitized by spinach, another common natural sensitizer for
dye
-
sensitized solar cells, and the performance proved t
o be significantly better. The fact that
Calotropis
is a non
-
food plant is an added advantage to utilizing it as a dye source, along with its
intrinsic heat resistance that allows it to survive the harsh desert conditions all year round.
