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.
