Semi-transparent solar cells achieve record-breaking energy conversion | The solar cells can be teamed up with tandem solar cells and also pave the way for use in windows to tap into solar energy.

The researchers used atomic-level computational science to determine how semi-transparent solar cells could be made more efficient and durable.

To prevent this performance degradation, a metal oxide layer was used as a buffer between the hole transport and the transparent electrode layer, which caused a reduction in charge that could be transported and the stability of the device. With inputs from the Energy AI and Computational Science laboratory, the team was able to recognize the cause of performance degradation while also finding out how lithium could help resolve the issue. To resolve this, the team found that converting lithium ions into lithium oxide prevented their diffusion into the metal oxide layer, making it much more stable.
