在150 ℃下制造的纳米颗粒ZnO染料敏化太阳能电池显示出与在450 ℃下制造的电池相似的性能。电化学阻抗谱表明，随着温度的升高和烧结量的增加，电池的表面缺陷减少，结晶度增加。这一趋势得到了染料解吸、IPCE和瞬态测量数据的支持。虽然这对Voc有影响，对Jsc有更明显的影响，但总体转换效率仅受到轻微影响。如果要大规模制造电池，较低的烧结温度将导致显着的成本和能源节约，并且是迈向染料敏化太阳能电池工业化的积极步骤。
Nanoparticulate ZnO Dye Sensitised Solar Cells fabricated at 150 C showed similar performance to cells fabricated at 450 C. EIS was used to show that the cells showed a reduction in surface defects and an increase in crystallinity as the temperature was increased and the amount of sintering was greater. This trend was backed up by data from dye desorption, IPCE and transient measurements. While this had an impact on the Voc and a more pronounced effect on the Jsc the overall conversion efficiency was only marginally affected. A lower sintering temperature would lead to a significant cost and energy saving if the cells were to be manufactured on a large scale and is a positive step towards the industrialisation of dye-sensitized solar cells.
