Embodiment Construction
[0015] Take a microammeter, a millivoltmeter, a slide wire resistor with a resistance of 100 megohms, wires and a titanium dioxide dye solar cell. The effective area of the titanium dioxide dye solar cell is 2 square centimeters, and it has two metal leads to facilitate the output of photo-generated voltage and current. Connect one output electrode of the titanium dioxide dye solar cell to one input terminal of the ammeter, then connect the output terminal of the ammeter to one terminal of the variable resistor, and then connect the other terminal of the variable resistor to the other terminal of the solar cell An output pole completes the main line connection. Connect the two terminals of the voltmeter to the two output electrodes of the solar cell to read the output voltage of the solar cell. figure 1 It is a circuit diagram of the testing instrument constructed according to the embodiment.
[0016] Use the light emitted by the solar simulator to illuminate the solar cel...
