Unclean energy has become undesirable, as it pollutes the environment such as coal and
petroleum so the whole world turned to using clean, renewable and sustainable energy.
Therefore, this project was done to design a solar cell through thermal evaporation that
works as an energy source.
Through smelting, copper indium diselenide duo were prepared from their basic elements
with a high degree of purity.
Then CuInSe2 thin film was deposited using thermal evaporation procedure. Indexing the
CuInSe2/n-Si heterojunction's dark and illumination I-V characteristics curve was done
at room temperature. The photovoltaic (PV) properties and several parameters of the
Au/CuInSe2/n-Si/Al device have been obtained from the white light's illumination
conditions. Solar cell efficiency is equal to 5.7% .
The future belongs to the CuInSe2 solar cell.
