More data makes the database more valuabel

The database was initiated by collecting all perovskite device data up to the end of February 2020. Our vision is that the perovskite community should embrace this as a valuable resource and start to upload also new data so that we can stay up to date and build what we can think of as the Wikipedia of perovskite science.

We thus encourage anyone to upload new device data. Ideally, we would like to have data for every device ever made, regardless if it is a highly efficient or a failed device, but some data is much better than no data.

Data extraction protocol

To upload new data to the database, the data must be formatted consistently with respect to the data already in the database. The backend for inserting data to the database consists of an Excel template defining all categories found in the database together with formatting guidelines. The latest version of the data extraction protocol can be downloaded here. Instructions for how to fill in the template are found in the template. The instructions are also available as a separate file that can be downloaded below.

Upload data

To upload data entered in the data template, you go the data upload app hosted by MaterialsZone.

The app is found under “Insights >> Perovskite Database Project” in the left side menu in Materials Zone’s system found on the link below (see instructions here on how to obtain access to the interactive graphics)

Reasons for uploading data

Uploading new data will take some time and effort. That is unavoidable, but there are several good reasons to why it is worth that effort.

  • This project demonstrates the power of aggregated datasets adhering to the FAIR data principles, and that alone should provide an incentive to contribute.
  • Sharing data in this way gives it new life and draws additional attention to the original publication
  • Sharing data in this way is a way to comply with the demands for openness more frequently seen from taxpayers, funding agencies, and publishers.
  • Uploading as much data as possible, both for good and bad devices, is a service to the community which helps to accelerate the development of new solar cell technology.
  • Finally, by planning for sharing data already from the start of a project, the tools and protocols provided here can help in organising and improving local data management and thereby in the end simplify planning, analysis, and writing.
