What can we learn from the Silicon PV conference in Constance?
It was particularly technical. We refer readers who are interested to the article :
- Metallization and transparent conductive oxides in cell production.
The latest N-type cell technologies, in particular the heterojunction, require much more money than previous generations. And as the manufacture of solar cells develops, the consumption of these materials is becoming increasingly problematic. Trials are being carried out with thinner TCO layers and the replacement of silver screen printing with copper plating.
- Work is being carried out on a heterojunction cell stack without a TCO layer.
- 80% of indium could be replaced by aluminium and zinc oxide.
- Silver can be replaced by copper, which could potentially lead to other improvements in the cell stack. Other work involves stretching silver filaments, which reduces consumption from 1.9 mg per line to 0.7 mg.

- Perovskites: not if, but when (and how)
- Richness of new materials/approaches
