During the last two exhibitions, new products of Tempress and SoLayTec were revealed. Especially for the next PERC2.0 expansions those products are highly requested by the market. The 2nd Generation InPassion ALD combined with the newest direct PECVD can annually produce up to 130MW including the integrated anneal process.
Furthermore, two weeks ago the 25th Intersolar exhibition and EUPVSEC conference were held in Munich. In several presentations the InPassion ALD was an important topic. Research institute Imec presented its latest results regarding n-type IBC cells on 156x156mm2 using Al2O3 from SoLayTec. Furthermore Hanwha Q Cells presented its evaluation results of InPassion ALD versus MW-PECVD and SoLayTec gave an overview of its successful PERC integration project of one of their key customers.
PERC2.0
“For PERC integration the Al2O3 ALD machine only, is not the complete solution. A customer also needs a PECVD capping machine for covering the Al2O3 layer. So far a customer needed at least 6 direct PECVD tubes to meet the ALD output of 3600wph. Since 10th SNEC exhibition in Shanghai Tempress introduced the SPECTRUM PECVD which has at least the same nett capacity as the InPassion ALD. So now capex wise we have a highly cost effective solution available for our customers”, said Roger Görtzen, co-founder of SoLayTec and director marketing and sales. “Especially if we take into account that the uptime, throughput, TMA usage and efficiency gain are even better than our main competitor. On top of that, the newly introduced 2nd generation InPassion ALD has been improved a lot. The main point that has been improved is the uptime and nett throughput of the machine”, according to Roger Görtzen.
