Well crystallized Aluminium (Al) doped Titanium dioxide (TiO2) nanoparticles with various doping concentration (0, 0.05[Formula: see text]M, 0.07[Formula: see text]M, 0.09[Formula: see text]M and 0.11[Formula: see text]M) were synthesized successfully by sol–gel route to develop the photo anode of Dye Sensitized Solar Cell (DSSC). Anatase crystalline nature of TiO2 nanoparticles was confirmed using X-ray diffraction (XRD) and Raman spectrophotometer. The Atomic Force Microscopy (AFM) was used to investigate the morphology of the photo anode (Al-doped TiO2 nanoparticles). The photovoltaic performance of the DSSC in terms of Current, Voltage and efficiency was investigated with a standard illumination of AM1.5G having an irradiance 100[Formula: see text]mW/cm2. Optimized values of Short Circuit Current density ([Formula: see text]), Open Circuit Voltage ([Formula: see text]) and efficiency ([Formula: see text]) obtained was 247.62[Formula: see text][Formula: see text]A/cm2, 359[Formula: see text]mV and 0.02456%, respectively for 0.07[Formula: see text]M Al doping concentration. Eco-friendly Eosin Y dye was used for sensitization of the photo anode. The optimized photovoltaic cell exhibits very good efficiency (80.05% more than the earlier reported work).

Titanium dioxide (TiO[Formula: see text] nanoparticles have been synthesized by the cost effective Sol–Gel technique. Characteristics of TiO2 nanoparticles were investigated by X-ray diffraction and Fourier Transform Infrared spectroscopy. The Eosin Y dye and dye extracted from Hibiscus tea have been successfully used in fabrication of the dye sensitized solar cell. The photovoltaic performance of the dye sensitized solar cell indicates that the short circuit photo current, open circuit voltage and efficiency of the DSSC using Eosin Y dye is 10 times more compared to the DSSC using the Hibiscus dye.

Pada penelitian ini dilakukan sintesis nanopartikel TiO2 menggunakan metode sol-gel dengan pelarut air. Pada proses sintesis ditambahkan kitosan dengan konsentrasi 0; 2,5; 5; dan 10% v/v. TiO2hasil sintesis kemudian dikarakterisasi dengan menggunakan SEM, XRD, dan BET  untuk mengetahui morfologi,  struktur kristal, dan karakteristik pori. Selain itu keempat variasi TiO2diaplikasikan sebagai foto elektroda DSSC. Karakterisasi DSSC dilakukan dengan menggunakan solar simulator AM 1,5 untuk mengetahui karakteristik I-V DSSC. Hasil karakterisasi menunjukkan penambahan kitosan pada konsentrasi rendah (2,5% v/v) mengurangi fasa anatase pada kristal  TiO2dan cenderung memperbesar ukuran kristalit. Penambahan kitosan melebihi 5% meningkatkan fasa anatase dan memperkecil ukuran kristalit. Konsentrasi kitosan 2,5% memperkecil luas permukaan spesifik partikel dan volume total pori. Peningkatan konsentrasi kitosan memberi hasil sebaliknya. Performa DSSC terbaik didapat pada TiO2 dengan konsentrasi kitosan 2,5% saat sintesis, dengan Voc = 0,58 V, Jsc = 0,74 mA/cm , dan η = 0,51%.Kata kunci: titanium dioksida, Dye Sensitized Solar Cell, kitosan
