Abstract
Provided are dye-sensitized solar cells in which a transparent conductive oxide is not used as a light receiving substrate and methods of fabricating the same. The dye-sensitized solar cell includes an upper electrode layer, which is disposed between a lower electrode layer and a photovoltaic conversion part and has through-holes, and a supporter disposed between the lower electrode layer and the light receiving substrate. The supporter may be a pore layer.
Claims21
A dye-sensitized solar cell, comprising:
- a photovoltaic conversion part disposed between a lower electrode layer and a light receiving substrate;
- an upper electrode layer having through-holes, the upper electrode layer being disposed between the lower electrode layer and the photovoltaic conversion part;
- a catalytic layer covering a top surface of the lower electrode layer, the catalytic layer being disposed between the lower and upper electrode layers;
- and
- an electrolyte solution disposed between the catalytic layer and the light receiving substrate.
A method of fabricating a dye-sensitized solar cell, the method comprising:
- preparing an upper electrode layer in which through-holes are formed;
- disposing the upper electrode layer having the through-holes on a lower electrode layer;
- forming a photovoltaic conversion part on the upper electrode layer;
- forming a light receiving substrate on the photovoltaic conversion part;
- and
- injecting an electrolyte solution between the light receiving substrate and the lower electrode layer.
