Special Issue Information

Dear Colleagues,

The energy crisis is one of the most challenging problems confronting mankind today. According to global energy estimations, the world’s energy consumption will grow by 20–30% or more through 2040.

Dye-sensitized solar cells (DSSCs), which are based on clean and sustainable solar energy, remain at the cutting edge of research. DSSCs offer the possibility to design low-cost solar cells with a high degree of flexibility in shape, color, and transparency. However, much more research needs to be done to commercialize them, and efforts need to focus on the development and optimization of each component of DSSCs in order to increase their long-term stability and efficiency while reducing costs and the environmental impact of the used materials. Moreover, in accordance with the theoretical maximum efficiency, which is suggested to surpass the Schottky–Queisser limit of 33%, designing tandem DSSCs could be a way to overcome their performance bottleneck.

Electrodes (photoanodes, photocathodes, and counter electrodes) are considered to be crucial components of DSSCs. They can be used to improve the photovoltaic performance, long-term stability, and cost of the devices that control photoconversion processes, such as dye adsorption, charge separation, light scattering, and electron transportation, and the regeneration of the redox mediator.

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. Crystals 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 2600 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.

The optimization of the photoactive electrode based on TiO2 with a complex architecture for UV dyes along with water-based electrolyte has successfully allowed us (i) to obtain a photovoltaic efficiency of the dye-sensitized solar cell with 1.45 times higher than the best efficiency reported for synthetic dye and 3 times for curcumin dye so far; (ii) transparency on the entire Photosynthetic Active Radiation domain; (iii) preserving high efficiency for lighting 1 sun (summer) and shading, especially for 60 mW/cm2, which represents the maximum illumination in the rest of the seasons. Our water-based dye-sensitized solar cells loaded with synthetic and natural UV dyes have revealed that the implementation of a dye-sensitized solar cell in autonomous greenhouses is a viable and inexpensive concept.
