The cathode of a DSC is a glass plate with a thin Pt dssc solar cell which serves as a catalyst. Both electrodes are pressed together and sealed so that the cell does not leak. An external load can be powered when light shines on the anode of the dye solar cell.

Principle of a Dye Solar Cell As the name implies, the mechanism dssc solar cell dye solar cells is based on the photo electrochemical processes. Figure 2 depicts an energy diagram of a dye solar cell.
Dssc solar cell following section describes all relevant electrochemical processes. Figure 2 — Energy diagram of a dye solar cell. Highlighted in red are all single steps which are explained in the text.
DSSC: Dye Sensitized Solar Cells
The dye molecule is initially in its ground state S. Electrons can now dssc solar cell freely as the semiconductor is conductive at this energy level. An electrical load can be powered if connected.
The output current depends strongly on the potential of the cell as well as dssc solar cell of the incident light. The current I of the cell is measured.

Dssc solar cell addition, a light source with a constant intensity is focused on the solar cell to generate power. Figure 3 — Schematic diagram of I-V curves with and without light. A dye solar cell behaves dssc solar cell a diode when no light is present.
No current is generated and energy is needed to power the cell. The solar cell generates now current which increases with increasing light intensities.
Current flux is nearly constant at lower potentials.

It reaches its maximum when the potential is zero. The generated current decreases with increasing potential.
Above this potential, an external bias voltage is needed to power the cell. The cell can get damaged at excessively high values. Figure 4 — Schematic I Dssc solar cell curve and power curve of a solar cell.
Several important parameters are shown.
Short circuit Current The short circuit current ISC is the highest current that can be drawn from a solar cell. The cell voltage is at dssc solar cell point zero.
Hence the generated power is also zero. Open circuit Potential The open circuit potential EOC is the highest voltage of a solar cell at a given light dssc solar cell.

It is also the potential where current flow through a dssc solar cell cell is zero. Power The generated power P of a solar cell can be calculated by the following formula: The resulting power curve exhibits a power maximum Pmax.
Fill Factor The Fill factor FF is an important parameter to specify the overall capabilities of a cell.
