The positive hole transport layer is prepared with CuPc, and the dye-sensitized heterojunction so. lar cells (DSH) is prepared with dihy-droindol-D102 (C37H30N2O3S2). For CuPc positive hole with different thickness, the performance of 40 nm, 80 nm and 120 nm cells is researched. When the thickness is 40 nm, sc=248.3 μA/cm2, Voc=0.61V and η=0.042% (80 mW/cm2 xenon lamp test). Comparing with the I3-/I-liquid electro. lyte dye-sensitized TiO2 solar cells, the low efficiency reason of DSH is analyzed.
