Effects of Substrate and Na Concentration on Device Properties, Junction Formation, and Film Microstructure in CuInSe2PV Devices

PDF Version Also Available for Download.

Description

Different concentrations of Na were systematically introduced into CuInSe2 (CIS) photovoltaic solar cell absorber material on different substrates (SLG, Si02/SLG, 7059, alumina) to: (1) determine the resultant effects on device properties, junction formation, and material microstructure; and (2) determine the optimal range of Na concentrations in the CIS films per specific substrate. In general, finished devices show improved Voc, Jsc, and device efficiency, improved charge-collection efficiency and, possibly, increased grain size as a result of the coevaporation of 4 to 100 mg of Na2Se during film deposition. However, a dramatic devolution set in with the addition of 235 mg of ... continued below

Description

Different concentrations of Na were systematically introduced into CuInSe2 (CIS) photovoltaic solar cell absorber material on different substrates (SLG, Si02/SLG, 7059, alumina) to: (1) determine the resultant effects on device properties, junction formation, and material microstructure; and (2) determine the optimal range of Na concentrations in the CIS films per specific substrate. In general, finished devices show improved Voc, Jsc, and device efficiency, improved charge-collection efficiency and, possibly, increased grain size as a result of the coevaporation of 4 to 100 mg of Na2Se during film deposition. However, a dramatic devolution set in with the addition of 235 mg of Na2Se, and all the aforementioned parameters were either at, or worse than, their pre-Na-addition levels. Meanwhile, although the device microstructure improves with Na addition and, more importantly, the junction (as characterized by electron-beam-induced current) has become much more uniform and closer to the heteroface, all that reverses with the ''Na overdose.''
