| Zusammenfassung | In order to compare organic solar cells and their electric properties to conventional solar cell types they have to be calibrated under standard test conditions (1000W/m², 25°C, AM1.5). But in contrast to conventional solar cells organic solar cells consist of very thin layers (~100nm) and are often encapsulated between two glass substrates. The lower thermal conductivity of glass causes a great difference between the temperatures in the solar cell and on the backside of the glass. In practice it is only possible to measure the temperature at the backside. This causes large uncertainties of the temperature inside the cell and hence introduces large uncertainties for a proper calibration. To reduce the uncertainties from the temperature it is necessary to get information about the inner temperature of the cell. Here we present results from measuring the inner temperature of an organic solar cell via a micro resistor directly pressed onto the metal back electrode inside the encapsulation and from a usual PT100 in a heat sink, which is pressed on the backside of the encapsulation glass. We observed a linear relation between irradiance and temperature difference between both temperature sensors. Finally we are able to reach nearly 25°C at the contact of the solar cell by controlling the temperature of the PT 100. |
