| Research Abstract |
CuInO_2 was selected as a candidate material for new concept solar cell because its crystal structure is composed of stacking of p-and n-layers perpendicular to its c-axis. We have prepared CuInO2 films whose c-axis perpendicular to substrate surface but not parallel ones by RF sputtering method : The parallel films were only prepared by using PLD method. Unfortunately, we could not demonstrate new concept solar cell with CuInO_2, however, important two parameters of CuInO_2, ionization potential and electron affinity, were determined by UPS and the origin of the bipolar conduction in CuInO_2 has been revealed.
