Abstract
A solar battery unit is proposed, including: a first electrode; a nano rough layer formed on the first electrode; a semiconductor active layer formed on the nano rough layer; and a second electrode formed on the semiconductor active layer, thereby enabling the nano rough layer formed on the first electrode to fully absorb solar energy not completely absorbed by the semiconductor active layer so as to allow solar energy to be fed back to the semiconductor active layer with a view to maximizing absorption of solar energy.
