The did at a frequency of 10KCl solution, respectively. The impedance potential test result is reference electrode were iron plot is shown functioning electrode, counter electrode, andshown in QX-222 manufacturer Figure 10a and also the MSpyrite sample, Pt in Figure 10b. It can be inferred that the conductive type of the wire and Ag/AgCl with saturated KCl remedy, respectively. film is n type since the -1 slope on the MS curve is positive [37]. When = 10.9 Figure [38] as well as the MS plot k = 4.3 in the impedance possible test result is shown in F m 10a and curve slope is shown 11 were made use of in Equation (7), the carrier concentration of ND = three.01 1019 cm-3 was ob10 Figure 10b. It could be inferred that the conductive variety of your film is n sort since the slope tained. The flat-band possible VBP = -3.70 = ten.9 F m-1 to beand curve slope k = 4.3 the 11 from the MS curve is positive [37]. When eV is also straightforward [38] calculated based on ten horizontal intercept (the value of KT/e is negligible of N = three.01 1019 cm- smaller) [37]. have been made use of in Equation (7), the carrier concentrationbecause it’s fairly also three was obtained. D We characterized the photovoltaic BW A868C Antagonist response of your iron pyrite film in PV devices, and also the structure of your device is shown in Figure 11a. The outcome is shown in Figure 11b. It shows that the device exhibits photovoltaic properties. The open circuit prospective (VOC), short-circuit present (ISC), and fill element (FF) of your device are 42.5 mV, 0.01 mA/cm2 and 25 , respectively. The dark J-V measurement (insert in Figure 11b) clearly indicated a rectification characteristic of your device.

The result is shown in Figure 11b. It shows that the device exhibits photovoltaic properties. The open circuit possible (VOC ), short-circuit current (ISC ), and fill aspect (FF) with the device are 42.five mV, 0.01 mA/cm2 and 25 , respectively. The dark J-V measurement (insert in Figure 11b) clearly indicated a rectification characteristic in the device. Even though the device efficiency is just not so attractive, the outcomes confirm the photovoltaic impact of the FeS2 thin film. It also suggests Figure 10.
