5/6 This new dye, coded Z991, exhibits a higher molar extinction coefficient and red-shifted response in comparison to the C101 (Fig. 5). This improvement is the outcome from the � conjugation extension. �� Fig. 5: Comparison between the IPCE spectra of the N719, C101 and the new Z991 dye which the structure is shown in figure 4. First non-optimized devices assembled with a DSL30NRD-T and DSL 18NR-AO photo-anode configuration sensitized with Z991 show almost 12.10 % and 12.40% conversion efficiency at full and half sunlight illumination which allows us to meet successfully our first deliverable. The coming work will be focused in improving further this Z991 dye in order to meet the threshold of 13% photon-to-electron conversion efficiency.

Main achievements - The association of the Dyesol DSL30NRD-T paste as transparent layer and Dyesol DSL18NR-AO as scattering layer provides the best photovoltaic performance in combination with the heteroleptic C101 dye. - A low temperature grafting approach has been optimized which gives champion photon-toelectron conversion efficiency of 11.9 % using the C101 dye. - New heteroleptic Ru-dye, coded Z991, based on two thiophene attached to the bipyridine unit has been successfully synthesized and the preliminary results show outstanding performance (above 12 % efficiency), in this respect we are ahead of the project. Based on these results our focus for next year will be optimization of Z991 dye and other near IR dyes to achieve the targeted 13 % efficiency as deliverables of D14. References [1] Y. Chiba, A.
