P-type dye sensitized solar cells (p-DSCs)[1] have attracted intense interest from scientists due to their potential application in tandem solar cells[2–4] and hydrogen generation devices[5–7]. Solid state p-type dye-sensitized solar cells (p-ssDSCs)[8] have been proposed and fabricated for the first time, using the organic dye P1 as the sensitizer on mesoporous NiO and phenyl-C61-butyric acid methyl ester (PCBM) as the electron conductor. The p-ssDSC has shown an impressive open circuit photovoltage of 620 mV. Femtosecond and nanosecond transient absorption spectroscopy has given evidence for sub-ps hole injection from the excited P1 to NiO, followed by electron transfer from P1- to PCBM.
