Abstract
The performance of poly-Si TFT fabricated by excimer laser annealing and the current-voltage characteristics of a-Si:H p-i-n solar cell were studied in the thesis. Solar cell was introduced between thin film transistor (TFT) and organic light emitting diode (OLED) to solve the contrast problem. Through the new design, both the sun light and the emitted light from OLED can be absorbed by the solar cell to achieve the energy-recycling OLED. By connecting every TFT drain with data lines and gate with scan lines, we will expand this energy-recycling device to a 4x4 energy-recycling array, which has practical applications in some mobile/portable electronic devices which are particularly power-aware. The integration of the three devices (TFT and OLED and solar cell) requires a low temperature a-SiNx passivation layer and a specially designed electrodes for OLED. Finally, the 4x4 energy-recycling OLED array consisting of 16 TFT, 16 solar cell and 16 OLEDs has been fabricated successfully.
