Temperature dependence of ohmic shunt resistance in mercury cadmium telluride junction diode

Experimental Method to Quantify the Leakage Currents of Solar Cells from Current Density-Voltage Characteristics

“…The resulting currents are added to the currents of the solar cell. An empirical expression for the current density in a solar cell is written in the following form [15][16][17][18][19][20]:…”

“…The value of this parameter (Rsh) gives information on the quality of a solar cell and its performance. Sometimes, the value of Rsh is deduced by extrapolating the linear part of the inverse J-V characteristic [15]. When a solar cell has low currents, as is the case with wide band gap semiconductor devices, this method remains difficult to apply because of noise in measurements at low polarizations.…”

Shunt current in InAs diffused photodiodes

“…However, it has been shown in early studies of photovoltaic devices that shunts may have linear (ohmic) as well as non-linear (diode) current-voltage characteristics [4]. In details, the shunt current was investigated in HgCdTe photodiodes [5][6][7]. The relevance of this problem has been also pointed out for InAs photodiodes [8], but to authors' knowledge the nature of the shunt current as well as the impact of surface conductivity on electrical properties of mesastructured InAs p-n junctions has not been investigated yet.…”
