The intense absorption in the red part of the visible range, and the presence of a lowest charge-transfer excited state, render Platinum(ii) diimine catecholates potentially promising candidates for light-driven applications. Here, we test their potential as sensitisers in dye-sensitised solar cells

Solar energy-conversion starts with the harvest of light, and its efficacy depends on the spatial transfer of the light-energy to where it can be transduced into other forms of energy. Harnessing solar power as a clean energy source requires the continuous development of new synthetic materials that
