“…We have synthesized and used this banana flower extract for DSSC fabrication using spin coating 11,12 and spray method 13 . The efficiency achieved by previous researchers in the development of DSSC by utilizing natural materials showed a significant increase from the smallest to the largest namely (tomatoes, 0.002%), 14 (cypress leaves, 0.062%), 15 (red spinach, 0.416%), (turmeric, 0.921%), 9 ( Phytolacca americana L., 3.04%) 16 and (co‐sensitizer of A. amentacea leaves and P. pterocarpum leaves, 8.22%) 17,18 . There are several DSSCs from natural dyes that show efficiencies achieved higher than 1%, this shows that the development of clean energy of light conversion using natural photosensitizer is very promising.…”

Summary The purpose of this study is to fabricate DSSC which performs well from natural pigments by giving exposure to microwave irradiation in materials to increase pigment uptake. In this research, the microwave irradiation was applied in coating banana flower extract (Musa acuminata bract) on the electrode, to increase light absorption of anthocyanin pigment. It is expected that the device can absorb more solar energy. The banana flower extract was characterized using Ocean Optic Vis‐Nir USB 4000 to observe the optical properties. The irradiation treatment was carried out using Electrolux Microwave (EMM 2308X) at power 150 W. The DSSC samples were characterized using I‐V meter Nacrieble 101. The maximum absorbance of 1.55 a.u. is found for the mass fraction of 0.45. The microwave irradiated device has an efficiency of about 3.69×10−6%, whereas which is no microwave irradiation has a maximum efficiency of about 0.57%. It shows that microwave irradiation can improve DSSC performance. The banana flower extract is available as an alternative organic photosensitizer in the fabrication of DSSC.

“…This research depicted that the mixture of dye may have two or more pigments resulting the high efficiency in DSSC, which was reported 8.22%. [ 12,20 ] The productivity of DSSC depends on the types of light‐harvesting pigments such as anthocyanin (flowers and fruits), chlorophyll (leaves), flavonoid (leaves, flowers, and fruits), and carotene (roots, stems, and flowers), with the absorption of solar radiation in the visible range. These pigments act as an antioxidant to form free radicals and prevent the plant from photodegradation.…”

Dye‐sensitized solar cells (DSSCs) have turned a new horizon in energy research due to their widespread exploration over two decades by improving efficiency, cost‐effectiveness, and easy process than inorganic‐based solar cells. The major challenges are metal complexes on designing the cells and sustainability implications for further rapid expansion due to its toxicity. To overcome the problems associated with metal complexes, the dyes are extracted from bionatural sources such as flowers, fruits, barks, petals, roots, leaves, and beans of plants. These organic dyes are being nontoxic, cost‐effective, abundant, environmentally friendly, and easy to extract, which is made them extensively applicable for DSSC. Through this review, readers may get an idea about the effect in the efficiency of the solar cell by applying variable semiconductors, effects of solvents, variable light‐harvesting pigments, types of electrolytes, and modification of counter electrodes by certain polymeric materials or nanomaterials. Furthermore, the effects of methodology, processing temperature, and pH of the medium during synthesis on solar cell parameters, such as the efficiency of DSSC, are critically analyzed which are reported by other researchers.

“…Titanium dioxide (TiO 2 ) nanoparticles have drawn interest due to their attractive solar cell, electronic, and photonic properties [1]. They have an extraordinary potential in different applications, for example, water purification, solar energy cell (DSSC), photocatalysis and gas-sensitive sensors [2,3]. Doping with rare earths (REs) and transition metals are utilized to change and enhance the action of titania under visible light [4][5][6][7][8].…”

Nano ceramics of pure TiO 2 and Dy 3+ , Eu 3+ and Tb 3+ doped TiO 2 are prepared by hydrothermal method and these are characterized by using X-ray diffractometer (XRD), UV-Visible spectroscopy, field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and photoluminescence spectroscopy. XRD analysis revealed that the average particle size of the pure TiO 2 and Dy 3+ , Eu 3+ and Tb 3+ doped TiO 2 are in the range of 45-35 nm and confirms the anatase phase. The FESEM and HRTEM analysis confirm that the obtained ceramics are in nano regime. The absorption spectrum revealed that the bandgap of the TiO 2 ceramics are in the range 3.14-3.2 eV. The PL analysis showed that the doping of Dy 3+ , Eu 3+ and Tb 3+ had improved the luminescence behavior than the pure TiO 2 nanoparticles. Overall, by doping 0.5 mol% concentration of rare earth (RE) greatly alters the structural morphology and directly influence the luminescence behavior of TiO 2 and suitable for advanced optoelectronic applications. The color purity of the studied samples is found to be 91% for Dy 3+ , 84% for Eu 3+ and 73% for Tb 3+ at the excitation of 345 nm, 376 nm and 350 nm respectively. The single-doped sample Eu 3+ : TiO 2 , Tb 3+ : TiO 2 and Dy 3+ : TiO 2 samples showed orange-red, blue-green and white emissions respectively.
