“…The fulfilment of these requirements would allow an effective action of dye‐sensitization towards the solar radiation for wide bandgap semiconductors of p‐type. The choice of the class of squaraine dyes is motivated mainly by the versatility of their synthetic chemistryand by the characteristic red‐shifted absorption with respect to the dyes commonly employed as sensitizers of DSCs . This represents an added value of the squaraine in the perspective of developing and assembling t ‐DSCs with the two photoelectrodes sensitized by dyes with complementary absorption features.…”

The design and the synthesis of three unsymmetrical squaraines, DS_34, DS_45, and DS_47, have been achieved for their utilization as sensitizers of screen‐printed NiO cathodes in p‐type dye‐sensitized solar cells (p‐DSCs). DS_34, DS_45, and DS_47 are bidentate dyes, each bearing two carboxylic anchoring groups, which differ solely in the length of alkyl chain attached to the nitrogen atom of the condensed pyrrole ring (ethyl, butyl, and dodecyl for DS_45, DS_34, and DS_47, respectively). The photoelectrochemical properties of the corresponding p‐DSCs are compared and analyzed in terms of the structural differences of DS_34, DS_45, and DS_47. The benchmark dye, p‐SQ2, has also been employed as a p‐DSC sensitizer for the sake of comparison. Current density−voltage (JV) curves and incident photon‐to‐current conversion efficiency (IPCE) spectra revealed the major efficaciousness of the DS_45 as a dye‐sensitizer, as it was the only system that produced a p‐DSC surpassing 0.04 % of overall efficiency (η). This finding was attributed mainly to the larger surface concentration of chemisorbed DS_45 with respect to the other squaraines.

Polymethine dyes as photosensitizers for dye‐sensitized solar cells (DSCs) are reviewed. The review provides a summary of design strategies, the main synthetic routes, and the optical and photovoltaic properties of polymethine dyes applied in hybrid photovoltaics. In particular, we focus on cyanine and squaraine dyes and their structure–properties relationships, highlighting the role of the active molecule design on device performance.

Solution‐Processable Design of Fiber‐Shaped Wearable Zn//Ni(OH)₂ Battery

et al. 2018

The rising of flexible and potable electronics urgently calls for matchable and miniaturized energy storage system as power supply. Herein, we develop a solution‐processable method to fabricate Ni@Ni(OH)2 fiber to design an all‐solid‐state fiber‐shaped Zn//Ni(OH)2 battery. This battery exhibits a high open circuit voltage of 1.75 V which is close to the theoretical value, considerable discharge capacity of 704 μAh cm−3 at current density of 0.5 A g−1, good rate capability with 75 % capacity retention when the discharge current increases from 0.5 A g−1 to 5 A g−1 and good cycling stability (92 % capacity retention after 2000 charge‐discharge cycles). Furthermore, the device performance remains unchanged under bending conditions, showing good flexibility and stability. It is believed that our design provides a promising strategy to fabricate long fiber‐shaped Zn//Ni(OH)2 battery as power supply for wearable electronics in future practical applications.
