The Perovskite Database Project is not an online course in the conventional sense, but an open database project built around data on perovskite solar cell devices. Its goal is to make past and future perovskite device data compliant with the FAIR principles: findable, accessible, interoperable, and reusable. In its early stage, the team reviewed more than 16,000 perovskite papers published up to the end of February 2020 and extracted sufficiently described solar cell device data from them. Data from papers published after that mainly depends on authors uploading it themselves.
In terms of subject area, it is highly focused on materials science, photovoltaic devices, and data analysis for perovskite solar cells, making it suitable for professional research scenarios. As for delivery format, the main site does not mention live classes, recorded lessons, or 1v1 instruction, so it should not be considered a structured teaching service. Certification or certificates are not mentioned either. The site content is in English, and the linked resources also lean toward international research platforms, so it is best suited by default to users who can read research materials in English.
The main content does not include any paid, subscription, or purchase information, and it explicitly mentions an open database and open-source tools. Its core resources can therefore be regarded as largely free and open. The platform emphasizes that even people without programming experience can use its interactive tools to explore, search, filter, analyze, and visualize data, which is helpful for materials researchers without a data science background. However, a certain foundation in perovskite photovoltaics is still needed to deeply understand field meanings, paper context, and device performance metrics.
Its strengths are its substantial data scale and research value. In the early stage, a large amount of device information from the literature was manually curated, and visualization and analysis tools are provided, making it useful for literature reviews, tracking performance trends, and reusing data. The open-source code also makes secondary development easier for research teams. The drawbacks are that it lacks a course syllabus, instructor explanations, a learning path, assignment feedback, and a certificate system. Data after 2020 relies on author uploads, so completeness may not match the earlier phase of systematic manual curation. In addition, the resources have been migrated from MaterialsZone to NOMAD, and the original site now functions more like an entry-point information page.
It is suitable for perovskite solar cell researchers, materials science graduate students, engineers working in photovoltaics, and anyone who needs to analyze device data. It is not suitable for learners who want to study photovoltaics or materials science systematically from scratch. The main text does not explain access conditions from China. The actual availability of NOMAD and GitHub links may depend on the network environment, so it is advisable to prepare alternative research channels such as paper databases, Materials Project, or university course resources.
