ALD grown bilayer junction of ZnO:Al and tunnel oxide barrier for SIS solar cell
{{output}}
Various metal oxides are probed as extrinsic thin tunnel barriers in Semiconductor Insulator Semiconductor solar cells. Namely Al2O3, ZrO2, Y2O3, and La2O3 thin films are in between n-type ZnO:Al (AZO) and p-type Si substrates by means of Atomic Layer Depositi... ...
