Core Problems In and the Commercialization Processes of Perovskite Solar Cells (PSC)

Dear Colleagues,

With the exhaustion of traditional fossil fuel energy resources, photovoltaic (PV) technology will play an increasingly important role in daily human life. Metal halide perovskite solar cells (PSC), which exhibit excellent light absorption properties, high carrier mobility, and are compatible with low-cost preparation, have attracted extensive attention over the preceding decade. With the gradual maturation of the mechanism understanding and preparation technology, PSC have achieved a power conversion efficiency (PCE) comparable to commercial silicon solar cells with the second-to-none growth rate in PV history. To date, PSC have obtained a certified PCE of 25.7% under laboratory conditions, 20.2%/20cm for photovoltaic modules, and 32.44% for perovskite/silicon tandem structure. The rates of progress is still advancing steadily. From the perspective of industrial preparation, the birth of many PSC start-ups, whether laboratories or industrial operations, in recent years has also laid the physical foundations for large-scale applications. It is certain that the industrialization process of PSC will be the focus of the PV industry in the next five years, will be deployed at the terawatt scale and will contribute to global decarbonization. This Special Issue, entitled “Core Problems in and the Commercialization of Perovskite Solar Cells (PSC)” aims to illustrate the critical issues encountered during the PSC commercialization process. Topics include, but are not limited to:

• Commercially available process for PSC fabrication;
• Impacts of the lead-containing PSC on environments;
• The strategy for achieving long-term stable PSC;
• Cost analysis for commercialized PSC;
• The specialized application of PSC besides PV.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
