Thiazolo[5,4-d]thiazole-based organic sensitizers with strong visible light absorption for transparent, efficient and stable dye-sensitized solar cells

A small set of thiazolo[5,4-d]thiazole-based D-π-A organic dyes, endowed with bis-pentylpropylenedioxythiophene (ProDOT) moieties in the π-spacer, was designed with the aid of computational analysis, synthesized and characterized. The presence of bulky and electronrich ProDOT groups beside the electronpoor thiazolothiazole unit induced optimal physico-chemical properties, including broad and intense visible light absorption. As a consequence, the dyes resulted particularly suitable for application in thin layer dye-sensitized solar cells (TiO2 thickness: 3.0-6.5 µm). Small-scale (0.25 cm2) devices prepared using standard materials and fabrication techniques gave power conversion efficiencies up to 7.71%, surpassing those obtained with two different reference dyes. Transparent larger area cells (3.6 cm2) also showed good η values up to 6.35%, not requiring the use of a co-adsorbent, and retained their initial efficiency over a period of 1000 h storage at 85°C. These results make this new family of organic sensitizers promising candidates for successful application in the production of efficient and stable transparent DSSCs for building-integrated photovoltaics

“…This makes DBR ideal candidates in applications where wavelength selectivity is important. For example, all‐dielectric mirrors have been proposed as low loss light trapping structures in weakly absorbing photovoltaic architectures, and used in colored or semi‐transparent solar cells to ensure reflection in the infrared while being transparent in the visible. Their integration within efficient and transparent UV filter systems, as well as gas or thermo‐optic imaging sensors have also been envisioned and studied …”

The optimization of functional optical devices requires the appropriate control of light propagation, which can be achieved by using engineered dielectric structures. Innovative materials combination and fabrication strategies are required to achieve a robust gain in performance without impacting manufacturing complexity and cost. In the present work, a novel liquid‐based approach is proposed for the simple and scalable fabrication of highly efficient and robust optical multilayer dielectric coatings. In particular, a sol–gel process is developed that enables the fabrication of large‐area distributed Bragg reflectors (DBR) integrating macroporous materials of controlled closed porosity. The DBRs have a very high index contrast, excellent and tunable optical properties, and high stability of performance and structural integrity with respect to crack formation and delamination, even against harsh ageing tests or solvent exposure. The potential of this approach to be integrated within existing optoelectronic architectures is demonstrated through the integration of a DBR structure as a back reflector in an amorphous silicon solar cell (a‐Si:H), resulting in a significant increase in light absorption, photocurrent, and overall efficiency. This opens the way towards simple dielectric engineering of robust photoactive devices based on the versatile use of liquid routes for the deposition of structured dielectric coatings.

One-dimensional photonic crystals: fabrication, responsiveness and emerging applications in 3D construction

et al. 2016

View full text Add to dashboard Cite

a One dimensional photonic crystal (1DPC), which is a periodical nanostructure with a refractive index distribution along one direction is widely studied by scientists. In this review, the material and fabrication methods of 1DPC fabrication are summarized. The applications are listed with a special emphasis on sensing platform and photovoltaic devices together with full color display. After that, some typical 3D ordered structures with stacked layers are highlighted, the fabrication method is also described and the remaining problems are pointed out. At last, the possibility to build 3D stacked structure based on 1D layers through chemical routes is discussed, which is relatively convenient and flexible. We believe such method is a promising substitute way to conduct 3D fabrication.
