Who we are
The research group of Stefan Weber is located at the Institute for Photovoltaics (Prof. Dr. Michael Saliba), University of Stuttgart. The purpose of our websites http://weber-nano.com and http://weber-nano.de is to inform the general public about our research activities. We process personal data gathered when visiting our websites in compliance with applicable data protection legislation. We neither publish your data nor transmit them to third parties on an unauthorized basis. In the following sections, we explain which data we record when you visit one of our websites, and exactly how they are utilized:
Scope of data processing
We only collect and utilize users‘ personal data to the extent required to ensure the functioning of our website and of our contents and services. The gathering and utilization of our users‘ personal data normally occurs after users have granted their consent. An exception occurs where data processing is legally permitted.
Legal basis of data processing
To the extent that permission of the affected individual is obtained for the processing of personal data, Article 6 (1) lit. a of the EU General Data Protection Regulation (GDPR) serves as the legal basis.
In the processing of personal data to fulfil a contract whose contractual party is the individual affected, Article 6 (1) lit. b GDPR serves as the legal basis. This also applies to processing required to implement pre-contractual measures.
If processing is required to safeguard the justified interest of the MPG or a third party and the interests, basic rights and basic freedoms of the affected individual do not outweigh the first-mentioned interest, Article 6 (1) lit. f GDPR serves as the basis for such processing.
Data deletion and storage duration
The affected individual’s personal data are deleted or blocked as soon as the purpose of the storage ceases to apply. Storage can also occur if provided for by European or national legislators in EU regulations, acts or other legislation to which the MPG is subject. A blocking or deletion of data then occurs only if a storage period prescribed by one of the aforementioned norms expires, unless a necessity exists in relation to the further storage of the data for the arrangement of a contract or the fulfilment of a contract.
