In the above paper (ibid., vol 3, no. 1, pp. 59-64, Jan. 2013), there is an error in the scale of Fig. 1. The corrected figure should appear as presented here. The correct maximum efficiency following the detailed balance model is close to 30% for a halogen lamp and for an incandescent bulb, respectively, and a bandgap close to the one of Germanium. The fluorescent tube reaches 50%, and the white...
Recent research focuses on developing photovoltaic cells that are optimized for indoor conditions and therefore suitable for photovoltaic energy harvesting in micro systems. The available conditions for indoor photovoltaic cells are investigated and discussed concerning intensity and spectra. The influence of the parallel and series resistances on the efficiency of crystalline and amorphous Silicon...
This paper presents a concept for rectifying low ambient radiation sources to supply autonomous measurement systems such as microsystems. In addition to an analytic computation and nonlinear simulation of the rectifier circuit with advanced design system (ADS), a circuit was built and the efficiency factor of the RF-harvesting system was measured. Matching the impedance is done by using an electrically...
