Dye-sensitized solar cells based on tin oxide nanowire networks

Highly crystalline tin oxide nanowires grown through vapor–liquid–solid process were used in Dye-Sensitized Solar Cells (DSSCs). Back-illuminated structure was adopted due to the opaqueness of silicon substrate used to grow the nanowires. To provides a good understanding of using metal oxide nanowir...
