Another order for RENA-SoLayTec as efficiency hits 20%
A tier one cell manufacturer has ordered a second RENA-SoLayTec machine to start producing PERC cells in their production base of mono-Si wafers in China. The customer used the ALD Al2O3 InPassion LAB tool from RENA-SoLayTec in their R&D department, which has been used for their research of high-performance solar cells. This tier one cell manufacturer is one of the first adopters of the Al2O3 passivation technology and has recently announced results of average conversion efficiency of over 20% with their p-type mono-Si wafers.
This tier one customer has decided to continue the transition of Al2O3 into mass production based on the superior quality of Al2O3 deposition using ALD and the related low costs per layer. "They have tested several Al2O3 solutions in its lab and we are proud that they have chosen our InPassion ALD technology for their next step towards mass production of their high efficiency cells", comments Roger Görtzen, manager marketing and sales and co-founder of SoLayTec.
The cell efficiency improvement of Al2O3 from RENA-SoLayTec leads to an increase of up to 1,0% efficiency gain. Further, InPassion ALD has many distinct advantages: with smaller footprint gained higher throughput; independent module design achieved flexible throughput and production; thinner deposition thickness greatly reduced the chemical consumption; lower running and maintenance cost compared with other technologies.
"RENA-SoLayTec is continuously working to reduce the Cost of Ownership for affordable Al2O3 deposition. Our main developments focus on increasing output using the same machine hardware and a further reduction of all consumables, but especially the TMAL precursor. In this way RENA-SoLayTec is able to provide cell manufacturers "best in class" efficiencies, combined with a very attractive commercial solution.", added Roger Görtzen.
