Solar energy can be utilized effectively for the production of electrical energy through dye-sensitized solar cells (DSSCs). Comparatively, these dye-sensitized solar cells are better than silicon-based solar cell because of their flexibility, lightweight, economical, environment-friendly and their simple route ofthe manufacturing process. Photoanode is the backbone of dye-sensitized solarcells and for obtaining better efficiency, the TiO2 films are irradiated with 600 KeV Fe ions at 2 × 1014 ions-cm−2 and 4 × 1014 ions-cm−2 fluency rates, respectively. X-ray diffraction results show that TiO2 film has anatase crystalline phases. Bandgap values, obtained through UV–visible spectroscopy; are being indicated a maximum reduction in TiO2 film using Fe ions irradiation at 4 × 1014 ions-cm−2. The electron-hole pairs recombination process are evaluated by PL specta and electrochemical impedence spectroscopy (EIS). The absorption spectrum shows a redshift after this ions irradiation. By J-V curve, corresponding efficiencies of all samples are calculated. For the fabrication of DSSCs based on dye (N719), pure TiO2 & TiO2 film exposed with 600 KeV Feions with a fluency rate of 2 × 1014 ions-cm−2 and 4 × 1014 ions-cm−2 are employed as photoanode in the present work and maximum 3.26% efficiency is achieved.

Fe离子束对TiO2基染料敏化太阳能电池结构、光学、光伏性能的影响

通过染料敏化太阳能电池(DSSC)可以有效地利用太阳能来生产电能。相比之下,这些染料敏化太阳能电池因其柔韧性、重量轻、经济、环保和制造工艺简单而优于硅基太阳能电池。光阳极是染料敏化太阳能电池的支柱,为了获得更好的效率,TiO 2薄膜分别以 2 × 10 14离子-cm -2和 4 × 10 14离子-cm -2 流率照射 600 KeV Fe 离子. X 射线衍射结果表明,TiO 2薄膜具有锐钛矿结晶相。带隙值,通过紫外-可见光谱获得;表明使用 4 × 10 14离子-cm -2 的Fe 离子辐射可使 TiO 2膜的最大减少。电子-空穴对复合过程通过 PL 光谱和电化学阻抗谱 (EIS) 进行评估。吸收光谱在该离子照射后显示红移。通过JV曲线,计算出所有样品的相应效率。用于制备基于染料 (N719) 的 DSSC,纯 TiO 2和 TiO 2薄膜暴露于 600 KeV Feions,流率为 2 × 10 14 ions-cm -2和 4 × 10 14 ions-cm-2在目前的工作中被用作光电阳极,并且实现了最大 3.26% 的效率。
