We developed thin film diode structures based on thin film a-SiC:H prepared by plasma enhanced chemical vapor deposition at a relatively high temperature on transparent conductive boron-doped diamond (BDD) with an underlying Ti grid. The optical absorption of the BDD/Ti electrode is about 10% in a broad spectral range and the sheet resistivity about 100 /sq. The diodes have been characterized by photocurrent, photoluminescence, Raman and electroluminescence spectroscopy, as well as optical absorption spectroscopy in the visible, near infrared and mid infrared regions. Diodes show a relatively high optical transparency in the near infrared region, a dark current rectifying ratio of more than 4 orders at ±1.5 V, short photocurrent density 15 mA/cm2 and an energy conversion efficiency of 4%.
