no coating is applied to the copper sheet in order to increase the absorbance of the sunlight

Copper has an atomic structure that readily shares electrons since it reacts by losing two electrons.
Thus increases its thermal conductivity and thus heat easily spreads through a Copper sheet.
It therefore does not require coating to increase its heat absorbency.
Also due to its high melting point it can retain large amounts of absorbed heat from the sunlight and this makes it suitable for solar appliances.
