Article Synopsis
- CdTe wires were created using a catalyst-free method through a technique called close space sublimation, which is suitable for large-scale production.
- The growth of these wires depends on surface roughness and deposition pressure, needing low roughness surfaces to succeed, and occurs via a vapor-solid-solid mechanism with CdTe seed particles acting as templates.
- Analysis shows that the CdTe wires have lower levels of recombination than regular CdTe films, making them more advantageous for semiconductor applications.
One of the big challenges of the 21st century is the utilization of nanotechnology for energy technology. Nanoscale structures may provide novel functionality, which has been demonstrated most convincingly by successful applications such as dye-sensitized solar cells introduced by M. Grätzel.
