Abstract

Structural and transport properties of CuInSe₂/ZnO heterostructure solar cell is investigated. X-ray diffraction pattern of CuInSe₂ films exhibited preferred orientation along (1 1 2) direction confirming chalcopyrite structure. Structural characterization through scanning electron microscopy revealed dense grains. The electrical properties of the solar cells were investigated using current-voltage (I-V) and capacitance-voltage (C-V) measurements. The dark I-V characteristics revealed that, in the low-field regime, conduction mechanisms follow Ohm's law and in the high-field region, space charge limited conduction was observed. Frequency-dependent capacitance studies were carried out to characterize the trap properties of the heterostructure.
