Abstract
In this study, temperature dependent current-voltage (I-V) measurements and investigation of the dc current transport mechanism of n-Si/MEH-PPV device have been performed. While the series resistance value displayed strongly temperature dependent behaviour, the ideality factor varied between 3.2 and 1.8 in the temperature range 110-330Â K. The temperature dependent ideality factor behaviour at low temperature region (110-220Â K) shows that tunnelling enhanced recombination is valid rather than thermionic emission theory and the characteristic tunnelling energy is calculated as 30Â meV. There is a slightly linear relationship between the ideality factor and temperature at region II (230-330Â K) which is attributed to drift-diffusion current transport in the n-Si/MEH-PPV device as stated already by Osvald.
