Photovoltaic cells are made of two thin layers of material, one of them being a semiconducting material such as silicon, the other a metal such as aluminum or silver.
(A) one of them being a semiconducting material such as silicon, the other a metal such as aluminum or silver
(B) one of them being a semiconducting material such as silicon, the other being a metal like aluminum or silver
(C) one of a semiconducting material such as silicon, the other of a metal such as aluminum or silver
(D) the first of the layers a semiconducting material such as silicon, the other layer a metal such as aluminum or silver
(E) the first silicon, a semiconducting material, the other silver or aluminum, both metals

Is "one of a semiconducting material such as...., the other of a metal such as....." correct? I thought it should be something like "one of them is a semiconducting material such as......, the other is a metal such as......".

Please clarify me! Thanks

Look at it this way

Photovoltaic cells are made of two thin layers of material, one (is made )of a semiconducting material such as silicon, the other (is made) of a metal such as aluminum or silver

here (is made) is elipsed
