We see the key to low-cost subsidized solar power in more efficient processes, loss reduction and low investment.
Our development to make solar energy affordable in the future is based on two core products:
1. We have developed a production line automation and processes that do not damage the surfaces of surface-sensitive solar cells of the latest generation (heterojunction, TopCON). This damage to conventional production equipment costs up to 1% efficiency in absolute terms.
2. we have developed a very robust recipe for highly efficient heterojunction cells (aSi passivation for +23%), which can be easily implemented on any PECVD system and thus simplifies the future process upgrade at the lowest investment.
