Forskningsöversikt (refereegranskat)abstract
- Dye-sensitized solar cells have attracted intense academic interest over the past two decades. For a long time, the development of new redox systems has fallen far behind that of the sensitizing dyes and other materials. However, the field has received renewed attention recently. In particular, in 2011, the Gratzel group published a record DSC efficiency of 12.3% by using a new Co-complex-based electrolyte. In this review, we will provide an overview of iodine/iodide-free redox systems for liquid electrolytes, and reveal that the design of an efficient redox system should combine with appropriate sensitizing dyes which is the pivotal challenge for highly efficient DSCs.

- Dye-sensitized solar cell (DSC) technology has grown into a massive field of research and development with a fast increasing number of scientific publications and patent applications. We have created a database for patents and patent applications that deal with dye-sensitized solar cell technology. In this paper the database has been used to analyze the number of patent applications over time, as well as technical, organizational, and geographical trends in patent applications for dye-sensitized solar cells. Activity in relation to DSC patents seriously took off after the millennium, with the majority of DSC patent applications coming from Asia. Almost 90% of the documents in the database derive from Japan, China, and Korea. From a technical perspective, approximately 75% of the DSC patent applications deal with DSC materials, mainly semiconductor materials, dyes, electrolytes, and device substrates. The DSC patent situation is complex and we recommend any potential manufacturer of DSC devices and/or DSC components to carefully analyze their freedom-to-operate.

Tidskriftsartikel (refereegranskat)abstract
- A water-soluble organic redox couple (TT-/DTT) and new organic dyes (D45 and D51) have been developed for aqueous dye-sensitized solar cells (DSCs). An optimal efficiency of 3.5% was obtained using the D51 dye and an optimized electrolyte composition. The highest IPCE value obtained was 68% at 460 nm.

Tidskriftsartikel (refereegranskat)abstract
- A low-cost spiro[fluorene-9,9'-xanthene] (SFX) based organic hole transport material (HTM) termed X60 was designed and synthesized using a two-step synthetic route. Devices with X60 as HTM showed high power conversion efficiencies (PCEs) amounting to 7.30% in solid-state dye-sensitized solar cells (ssDSCs) and 19.84% in perovskite solar cells (PSCs), under 100 mW cm(-2) AM1.5G solar illumination. To the best of our knowledge, this is the first example of an easily synthesized spiro-structured HTM that shows comparable performance with respect to the well-known HTM Spiro-OMeTAD in both ssDSCs and PSCs. Furthermore, the facile synthesis of X60 from commercially available starting materials makes this HTM very promising for large-scale industrial production in the future.
