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:

General Information

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.

Provision of the website and creation of log files

Each time you visit our website, our service and applications automatically record data and information from the computer system of the visiting computer.

The following data are gathered temporarily:

  • Your IP address
  • Date and time of your access to the website
  • Address of the page visited
  • Address of the previously visited website (referrer)
  • Name and version of your browser/operating system (if transmitted)

These data are stored in our systems‘ log files. These data are not stored together with the user’s other personal data.

The legal basis for the temporary saving of data and log files is Article 6 (1) lit. f GDPR. Storage occurs in log files in order to ensure the website’s functionality. The data also help us optimize the websites, eliminate malfunctions and ensure our IT system security. Our justified interest in data processing pursuant to Article 6 (1) lit. f GDPR also lies in such purposes.

The data are deleted as soon as they are no longer required to achieve the purpose for which they were gathered. If data are gathered for the provision of the website, this is the case if the respective visit is ended. In the instance that data are stored in log files, this is the case after seven days at the latest. Storage above and beyond this period is possible. In this case, the users‘ IP addresses are deleted or removed so they can no longer be allocated to the visiting client.

The recording of data for the provision of the website and the storage of data in log files is essential to operate the website. As a consequence, users do not have an option to revoke such data recording.
