Preparation and characterization of p-n homojunction Cu2O nanowire solar cells

摘要: This thesis presents an experimental study on the preparation and characterisation of p-n homojunction Cu2O nanowire solar cells. The investigated route starts with templated electrodeposition p-type nanowires. After dissolution template, free standing nanowires are left. Then a bottom layer is deposited final n-type fills voids forms junction. Nanowires were successfully deposited, however membrane was not successful; 40nm residual left, which resulted in impossibility to deposit layer. Without deposition, it tried create junction by directly depositing top Characterisation carried out chrono amperometric measurement NaSO4 linear sweep voltage measurements synthesised showed relatively high photocurrent density 47 μA/cm2. Most cells provided I-V curves, probably due internal short circuit. Although two like behaviour, no generated.
