Metrology for solar cells on large foils

SENTECH developed the new SenSol R2R measurement system for photovoltaics using large foil as substrate. Film thickness, optical as well as electrical properties of functional coatings can be measured on any position of the 2000 m long foils. For this purpose, transmission, reflection measurements and electrical metrology are applied. Challenging are flexibility and tension of the foil because they result in bulges and wrinkles.→read more


SENTECH was part of the project "Research on highly flexible optical precision layers on polymer surfaces (FlexCoPlas)" funded by the German Federal Ministry of Education and Research (BMBF). Within this project we have been able to develop a device, which carries out transmission measurements on foils and lenses. Further an optical broadband monitoring with adaptive strategy was developed based on the in situ transmission measurement. →read more


In April 2017 two of the major exhibition highlights for SENTECH took place in China. The SEMICON China 2017 was a must attend event for us.The SNEC 2017 PV Power EXPO which is the world leading photovoltaic exhibition was attended by SENTECH as well.The presentation of new plasma etching and deposition applications to the Chinese market as well as the promotion of the newly launched SENperc PV were the highlights of the two exhibitions. →read more
