Ohmic Direct conversion

Table 2 compares inverted solid-state photovoltaics with direct and indirect regenerative ohmic PEGs, each containing a GaAs wide band gap and an inverted aligned Si small band gap, and a variety of redox couples. As in the case of the bipolar systems summarized in Table 1, the solid-state device exhibits a marginally enhanced energy conversion efficiency compared to... 

The limiting equivalent circuit may be directly applied in analysis of power source performance because the direct-current response, which corresponds to the zero-frequency limit of the impedance spectrum, is of most importance. Conversion of Eqs (8) and (9) allow one to find the ohmic characteristics of a given power source at direct current. They also allow one to obtain a close initial guess for impedance fitting of the equivalent circuit by direct observation of the impedance plot. Ra will...
