Perovskite Database, led by HZB, rely on a team of approx. 100 collaborators world-wide that collectively are extracting all perovskite solar cell device data available in the over 15000 published perovskite papers. The extracted data includes metadata describing the devices, e.g. architecture, stack sequence, and deposition procedures, doping, and key characteristics for every layer in the stack, as well as key metrics for the device performance including for example efficiency and stability. The extracted data is codified and stored in an openly available database. Accompanying this database is a web page and interactive graphics which enable anyone to download, analyze, and learn from the data, as well as interactively slice and dice the data set in any way imaginable.
The Perovskite Database is based on a MySQL database storing data related to perovskite solar cell devices. This currently includes storage of both historically extracted literature data as well as future experimental data that anyone active in the perovskite field will be encouraged to contribute with. The second part is a Bokeh server with a set of interactive graphics that anyone can use for exploring the data in the perovskite database. The third and final part is the web portal which is the global access point to the project. From the web portal, the interactive graphics and the database can be reached, and this is where users can both download and upload data.
The original dataset comprising The Perovskite Database, was extracted from >17 000 papers on perovskite solar cells by a co-ordinated effort with 100 collaborators world-wide. The data extraction protocol included a parametrized description of the solar cell samples including the device architecture, stack sequence, precursor sources, solutions, deposition procedures employed, key characteristics derived from analysis of any layer in the stack, as well as key metrics for the device performance including for example sample size, device efficiency and stability.
Accompanying this database is a web page and interactive graphics which enable anyone to download, analyse, and learn from the data, as well as interactively slice and dice the data set in any way imaginable. The interactive graphics have also implemented a direct link of measurement point to original publications
The ambition of this infrastructure offered as part of VIPERLAB is to develop The Perovskite Database into an extensive data repository for the perovskite research community that enables literature research, provides an opportunity to disseminate scientific data according to FAIR data principles and generate new content based on the existing datasets and functionality.All gathered data will be openly available. All code for analysing and visualising the data will be made available open source. The VIPERLAB partner (HZB) will enable and support users of this infrastructure to create new content and functionality and integrate it with the existing platform upon request.
As a VIPERLAB infrastructure we will:
Supporting protocols and software tools developed by research groups and third-party providers that facilitate a connected dissemination path from internal lab data management to public dissemination
Access to The Perovskite Database will be offered through the access point for VIPERLAB’s virtual infrastructures (VAPo). Free access to all publicly available perovskite device data, interactive graphics, and the possibility to download/upload data will be granted upon sign-up/contact requests providing only Name and e-mail address as mandatory requirements. The source code for routines for data treatment, extraction, and visualisation will be available on GitHub
