“…The low efficiency of the flexible DSSC is attributed to the poor absorption of radiation due to the nonhomogeneous carbon/graphite layer, making the electrodes comparatively darker. However, the results were quite surprising, comparable to that of DSSCs fabricated on FTOs using Hibiscus 29 and purple eggplant as the dye 30 ; this made the low-cost, flexible DSSC stand worthy of its name. Since the DSSCs prepared on ITO substrates exhibited better efficiencies than the flexible ones, further characterizations were carried out only on them.…”

Dye-sensitized solar cells (DSSCs) are gaining considerable interest as substitutes to solar cells based on semiconductor thin-films owing to their costeffective and effortless fabrication methods. Efforts are being made to replace counter electrodes (CE) in DSSCs, which are conventionally based on noble metal platinum (Pt). Among the new materials as CE, two-dimensional (2D) transition metal dichalcogenide is one of the most explored to develop Pt-free DSSCs. We report here the preparation of TiO 2 -based DSSCs using beetroot (Beta vulgaris) extracts as sensitizers with carbon-, pristine-, and Ni (4%)-doped WSe 2 as the CEs. The Ni (4%) WSe 2 CE exhibited a high-power conversion efficiency (PCE) of 5.66% under the illumination of 100 mW cm À2 .The electrical characteristics, including I-V, C-V, and electrochemical impedance spectroscopy, corroborate the better efficiency of Ni (4%) WSe 2 CE. The cost-effectiveness and efficiencies obtained for Pure and Ni (4%) WSe 2 make them a worthy candidate as CE for DSSCs.

“…Campuran adsorpsi pewarna antosianin dan klorofil pada permukaan TiO2 dapat digunakan sebagai fotosensitizer untuk DSSC (Ahliha et al, 2017). Subodro et al (2017) telah meneliti pengaruh waktu perendaman lapisan TiO2 pada larutan antosianin yang berasal dari kulit buah manggis. Hasil yang diperoleh menunjukkan bahwa waktu perendaman 2s4 jam memiliki efisiensi penyerapan donor elektron lebih tinggi dibanding 12 jam dan 48 jam.…”

Ubi jalar ungu (Ipomoea batatas L., Poir) memiliki kandungan antosianin tinggi, bersifat alami sehingga menjadikan antosianin aman digunakan dan dapat diperbarui. Antosianin dapat digunakan sebagai dye dalam rangkaian sel surya pewarna tersensitisasi (SSPT). Antosianin diperoleh dari sel tanaman dengan maserasi dan pelarut etanol yang diasamkan dengan asam asetat. Tujuan penelitian untuk mengetahui tingkat keasaman pelarut dalam menghasilkan antosianin tertinggi, panjang gelombang serapan dan kemampuan dye sebagai donor elektron pada SSPT. Penelitian rancangan acak lengkap satu faktor dengan empat level keasaman (pH 4,00; 4,25; 4,50 dan 4,75), diulang 2 kali digunakan dalam penelitian ini. Pembuatan SSPT dengan cara perakitan elektroda kerja, elektroda lawan, elektrolit, dan dye antosianin. SSPT diuji di bawah sinar matahari selama 60 menit setiap hari untuk mengetahui kemampuan dalam menghasilkan tegangan dan arus listrik. Nilai absorbansi tertinggi sebesar 0,0485±0,20 dan kandungan antosianin terbaik sebesar 224,97±0,02 mg/100 g diperoleh pada perlakuan pH 4,00 dan panjang gelombang antosianin 520-700 nm. Dye antosianin sebagai donor elektron SSPT mampu menghasilkan tegangan listrik selama 15 hari dan arus listrik selama 10 hari. Tegangan listrik dan arus listrik tertinggi sebesar 0,25 volt dan 0,12 ampere. Kata kunci: antosianin, maserasi, sel surya pewarna tersensitisasi (SSPT), ubi jalar ungu
