摘要:
The present invention provides a photovoltaic cell comprising a photovoltaic conversion layer and a pair of electrodes. The photovoltaic conversion layer, being capable of converting incident light into a plurality hole-electron pairs, comprises a hole transport layer including a plurality of nanodots mixed therein for transporting the holes generated from the photovoltaic effect. The pair of electrodes are coupled respectively to two sides of the photovoltaic conversion layer for conducting holes and electrons. In another embodiment, the present invention further provides a method for forming the photovoltaic cell, wherein the nanodots are mixed in a solution formed of a hole transport material and then a hole transport layer having the nanodots is formed on a conductive substrate. In the photovoltaic cell having nanodots of the present invention, the hole mobility is enhanced so as to improve the efficiency of the photovoltaic cell.
