Integrating the Ca/Al stack into a partial rear contact solar cell architecture fabricated on a lightly doped (N_D = 4.5 × 10¹⁴ cm⁻³) n-type wafer resulted in a device efficiency of η = 17.6% where the Ca/Al contact comprised only ~1.26% of the rear surface. We demonstrate an improvement in this cell structure to an efficiency of η = 20.3% by simply increasing the wafer doping by an order of magnitude to N_D = 5.4 × 10¹⁵ cm⁻³.]]> Sat 24 Mar 2018 08:43:54 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43580 Mon 26 Sep 2022 10:12:18 AEST ]]>
