CIGS Thin Films and Solar Cells

Dear Colleagues,

In the past few years, thin film solar cells based on Cu(In,Ga)Se₂ (CIGS) have achieved remarkable progress in terms of conversion efficiencies (>22%) and production capacity, exceeding 1 GW/year. However, the field faces continuous evolution and further improvements are awaited, both in fundamental studies and in applications.

In addition, the opto-electronic properties of CIGS, such as high photon absorbance and a tuneable composition, make them attractive for a range of novel structures (bifacial, flexible, semi-transparent, tandem cells) to increase light harvesting and for use in the emerging field of BIPV (building integrated) or PIPV (product integrated).

This Special Issue of Applied Sciences, “CIGS Thin Films and Solar Cells”, is intended for a wide and interdisciplinary audience, and covers recent advances in:

- innovative concepts to increase CIGS-based device performance and to reduce costs

- development of new deposition techniques and processing

- alternative CIGS solar cell architectures

- improved characterization methods and theoretical modelling

- optimization of the CIGS modules and updated market analysis.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
