SoLayTec today announced the continuing positive trend of incoming orders.
Four new solar customers around the globe have ordered the Atomic Layer Deposition (ALD) equipment from SoLayTec. One of these customer is from Taiwan, and a mayor a step to open further opportunities for SoLayTec in this market. These shipments are scheduled to start within this quarter.
“After several years of having InPassion ALD systems in mass production at multiple customers in China and Japan, SoLayTec is delighted to announce that in the last couple of weeks 3 orders were received”, according Roger Görtzen, co-founder of SoLayTec and manager marketing and sales.
“These machines will be used for production of high efficient solar cell concepts, like p-type PERC, n-type IBC and bi- facial cells. In the past SoLayTec announced that spatial ALD results in a higher efficiency of about 0,2% for multi and mono PERC cells compared to PECVD AlOx. At one leading PV solar cell manufacturer we have measured for ALD Al2O3 a surface recombination velocity between 1- 5cm/sec compared to ≥ 30cm/sec on similar material for PECVD AlOx . This data confirms that the passivation quality of ALD Al2O3 is factor ≥ 6 higher compared to PECVD AlOx. Recently, the c-Si wafer quality has been improved, and this results into better bulk material of the c-Si material. Consequently our customers request an excellent surface passivation which can be provided by ALD Al2O3 for their future cell concepts.” according Roger Görtzen.
