其他摘要:Electrical and photoelectrical properties of nCdS-pInP hetero-junctions with and without intermediate p o InP epitaxial layer were studied. It was established that the current flow mechanism at direct biases is determined mainly by the recombi- nation processes in the space charge region of the junction. At the reverse biases the tunneling processes are predominant. The presence of p o InP layer leads to the photo-electrical parameters enhancing of hetero-junction: short circuit current increases up to 28,2 mA·cm -2 , open circuit voltage up to 0,780V and the efficiency of solar energy conversion up to 15 % (at 300 K and illumination of 100mw/cm 2 ). The photo-sensitivity of nCdS- p o InP -pInP is in the wavelength region of λ= 550-950nm with a maximum localized to λ =700-850nm
