A simple method has been developed for the preparation of photoanode paste from hydrothermally synthesized nanocomposite, using different nature of polymers viz. , synthetic: poly(vinyl alcohol) and polystyrene (PS) and natural: casein and sodium alginate (NaAlg) as binders. The titanium dioxide (TiO 2 )/multi-walled carbon nanotube (MWCNT) nanocomposite powder and film were characterized for analysis of their structure, crystallinity and morphology by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. Dye-sensitized solar cells (DSSCs) were fabricated using TiO 2 /MWCNT composite paste made with different binders as photoanode, N719 dye, platinum as photocathode and Idolyte HI-30. The observed results of photocurrent density–voltage characteristics and electrochemical impedance spectroscopy suggested that the nature of the binder used in making photoanode film showed significant influence on the overall characteristics of DSSCs. Among the cells fabricated, the DSSC fabricated using TiO 2 /MWCNT-PS binder showed highest power conversion efficiency of 3.03%.

聚合物作为粘合剂的性质对制作光阳极层的影响及其对染料敏化太阳能电池效率的影响

已经开发了一种简单的方法，用于从水热合成的纳米复合材料制备光阳极糊剂，使用聚合物的不同性质，即。，合成：聚（乙烯醇）和聚苯乙烯（PS）和天然：酪蛋白和海藻酸钠（NaAlg）作为粘合剂。通过X射线衍射、傅里叶变换红外光谱、扫描电子显微镜和透射电子显微镜对二氧化钛（TiO 2 ）/多壁碳纳米管（MWCNT）纳米复合粉末和薄膜进行了表征，对其结构、结晶度和形貌进行了分析。染料敏化太阳能电池 (DSSC) 是使用 TiO 2 /MWCNT 复合浆料制造的，该复合浆料由不同的粘合剂作为光阳极、N719 染料、铂作为光阴极和 Idolyte HI-30。光电流密度-电压特性和电化学阻抗谱的观察结果表明，用于制造光阳极薄膜的粘合剂的性质对 DSSC 的整体特性有显着影响。在制造的电池中，使用 TiO 2 /MWCNT-PS 粘合剂制造的 DSSC 显示出最高的功率转换效率，为 3.03%。
