The second part of the dissertation describes the fabrication and development of organic photovoltaic devices, which potentially can be used to power the wireless chip of the implantable biosensor described above. These photovoltaics are based on ternary mixtures of C60, a polycarbonate linked TPD (N, N, N', N'-tetrakis(phenyl) benzidine)) polymer (PTPD), and a small molecular weight radical salt of a TPD derivative, in an ITO/blend/AI configuration. We demonstrated that the incorporation of the radical salt into the PTPD/C 60 mixture provided 7 times improvement, from 0.06% to 0.47% in the power conversion efficiency (etaE), a substantial value considering that it originates from a 2, 500 A thick amorphous photoactive layer.However, as mentioned earlier, such membranes impedes the response time of the sensor. ... While this is not a serious problem for an O2 sensor itself, it could potentially be a problem when the 02 sensor is placed in closed proximity to ananbsp;...
