本发明公开了一种以市售粉末为原料制备二氧化钛丝网印刷浆料的技术，以制备出厚度超过17微米的纳米晶层而不开裂和剥落，用于染料敏化太阳能电池的光活性电极。利用单层半透明二氧化钛薄膜获得了8.7%的转换效率。利用透明和光散射型的二氧化钛薄膜组成的双层膜作为光子捕获系统，获得了9.2%的转换效率。版权所有(C)2007 John Wiley&Sons，Ltd.
A preparation technique of TiO2 screen-printing pastes from commercially-available powders has been disclosed in order to fabricate the nanocrystalline layers without cracking and peeling-off over 17 mu m thickness for the photoactive electrodes of the dye-sensitised solar cells. A conversion efficiency of 8.7% was obtained by using a single-layer of a semi-transparent-TiO2 film. A conversion efficiency of 9.2% was obtained by using double-layers composed of transparent and light-scattering TiO2 films for a photon-trapping system. Copyright (C) 2007 John Wiley & Sons, Ltd.
