<P>We have designed and developed an unsymmetrical zinc phthalocyanine (TT9) sensitizer that consists of three <I>tert</I>-butyl and two carboxylic acid groups that act as “<I>push</I>” and “<I>pull</I>”, respectively. The two carboxylic acid groups graft the sensitizer onto the semiconductor surface resulting in enhanced stability under heat and light compared to the similar unsymmetrical zinc phthalocyanine (TT1) sensitizer that consists of three <I>tert</I>-butyl and only one carboxylic acid groups. The solar cells containing the TT9 and TT1 sensitizers with non-volatile electrolyte were subjected to light soaking conditions at 60 °C. Under these conditions, the short circuit current of the TT1 sensitized solar cell after 1000 h decreases to half of its initial value where as the TT9 sensitized solar cell remained the same demonstrating the influence of number of anchoring groups on the stability of zinc phthalocyanine sensitized solar cells.</P> <P>Graphic Abstract</P><P>Phthalocyanine TT9 (red) grafts onto the semiconductor surface resulting in enhanced stability compared to TT1 (black). <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c0sc00602e'> </P>

<P>Tin oxide is an excellent candidate to replace mesoporous TiO2electron transport layers (ETLs) in perovskite solar cells. Here, we introduced a SnO2layer by a low-temperature solution process, and investigated its morphology, opto-physical and electrical properties affecting the device performance. We reveal that low-temperature processed SnO2is self-passivating in nature, which leads to a high efficiency. To further enhance the blocking effect, we combined a compact TiO2underlayer with the SnO2contact layer, and found that the bi-layered ETL is superior compared to single layers. The best device shows photovoltaic values in a planar structure with a short-circuit current density (<I>J</I>sc) of 22.58 mA cm<SUP>−2</SUP>, an open-circuit voltage (<I>V</I>oc) of 1.13 V, a fill factor (FF) of 0.78, and a power conversion efficiency (PCE) of 19.80% under 1 sunlight illumination.</P>

<P>Solid-state dye-sensitized solar cells were fabricated using an organic dye, 2-cyanoacrylic acid-4-(bis-dimethylfluoreneaniline)dithiophene (JK2), which exhibits more than 1 V open-circuit potential (V(oc)). To scrutinize the origin of high voltage in these cells, transient V(oc) decay measurements and density functional theroy calculations of the interacting dye/semiconductor surface were performed. A negative conduction band shift was observed due to the favorable dipolar field exerted by the JK2 sensitizer to the TiO(2) surface, at variance with heteroleptic Ru(II)-dyes for which an opposite dipole effect was found, providing an increased V(oc).</P>
