year

i. 4ºC lower NOCTii. Less prone to hotspots – PCB = heat sinkiii. Almost no FF lossiv. TCT test supreme to any other modules

Module reliability advantages

i. Production platform for MWT today and IBC & HJ-BC cells tomorrow

ii. 1 time cell handling instead of 7 times, resulting in higher yield and fewer (micro)cracks

iii. 4 operators needed for front-end assembly instead of 12

iv. High throughput in one line: up to 90 modules/hour

v. Upgradeable equipment

vi. Inbuilt inspection steps for quality monitoring

vii. Long equipment autonomy

viii. Suitable for half cell mfg

Production advantages

Our Unique Selling Points:

i. About 3 GWp installed equipment base

ii. Reliable and high precision equipment

iii. Strong IP position

iv. Extensive process knowledge

v. 15 years process experience
