The impact of annealing on copper-plated heterojunction solar cells
Why it matters: Optimizing annealing could improve efficiency and durability of copper-plated heterojunction solar cells.
- UNSW-led team identified that annealing conditions are crucial for the structural integrity of copper-plated heterojunction solar cell contacts.
- Fast annealing was found to increase microstrain in both the copper and indium tin oxide components of the solar cells.
A UNSW-led team has discovered that the annealing process critically influences the stress, strain, and microstructure within copper-plated heterojunction solar cell contacts. Specifically, rapid annealing conditions lead to an increase in microstrain in both the copper and indium tin oxide layers, impacting the overall cell performance.
