“…Dye-sensitized solar cells (DSSCs) have attracted considerable attention for the future generation of solar cells with a wide area of application such as window glass, car windshields, mobile chargers, or exible and transparent solar cells due to their abundant, non-toxic, low-cost, and renewable sources. 1,2 The natural dyes in DSSCs are obtained from organic sources such as anthocyanin, chlorophyll, betalain, and carotenoid. 3 The dye absorber materials are bonded to the TiO 2 porous material in order to broaden the semiconductor lm absorbance.…”

“…TiO2 sensitized dye photoelectrode and Pt counter electrode were assembled by using suryline polymer that followed the procedure of Prima [7]. The electrolyte solution, EL HSE, that obtained from Dyesol was dropped into the hole of counter electrode and then the hole was sealed by another suryline to prevent electrolyte leakage.…”

Abstract. The adsorption characteristic of natural dye has been studied on harvesting light using purification process. The purification process used for separation pigment photosynthesis of syngonium leafs was called fractionation. The first fractionation of the dye contains pigment of β-carotene . The absorpton spectrum of β-carotene has been investigated by using Uv-Vis spectroscopy. The Fourier Transform Infrared revealed that the binding of the dye was on the surface of TiO2. Analysis absorbance and energy gap of the dye has been investigated by using Uv-Vis spectroscopy and Tauc relation. The cells were illuminated under 100 mW/cm 2 AM 1.5 condition. The performance of the cells with sensitized the fractionation dye has a short circut current density (Jsc) of 0.27 mA/cm 2 , an open circuit photovoltage (Voc) of 0.4V, and Fill Factor (FF) of 68.89%. Furthermore, the overall efficiency of DSSC is 0.074%. The low efficiency for the fractionation cell based dye sensitized solar cells due to the weakness of interaction between dye molecule and the surface of TiO2.

“…The electrolyte mediator (iodide ion become tri-iodide ion) is needed for supplying electron to regenerate this oxidized dye so the dye will return back to the ground state condition. Finally, the electron will be captured by triiodide ion to form iodide ion (Prima et al, 2017).…”

This study aims to investigate solar cell as learning multimedia to improve students' scientific literacy on science and nanotechnology. Specifically, it describes learning design, the characteristic of developed learning multimedia and the description of learning activities using solar cell as learning multimedia to improve students' scientific literacy on science and nanotechnology. The method used in this research was Educational Research and Development that only consist of 3 stages. On the define stage, the research was conducted through literature review analysis, observation, and interview. On the design stage, the research was conducted through composing the instrument, developing solar cell as learning multimedia to improve students' scientific literacy on science and nanotechnology and composing teaching learning design. On the develop stage, the research was conducted through teaching learning activities using solar cell as learning multimedia to improve students' scientific literacy on science and nanotechnology. The research instruments were interview guideline, observation's sheet, judgment's sheet and questionnaire. Based on result and discussion, it can be concluded that learning design potentially improve students' scientific literacy. It is relevant with learning material and in accordance with the competence aspect, attitude aspect, and STL learning model. The characteristics of learning multimedia containing science and nanotechnology on solar cell context are: can be used classically, not individually, student-centered oriented, presenting the learning material using concept approach and context oriented, presenting the superiority of photochemistry solar cell with nanotechnology, visualizing the redox reaction concept on solar cell, and presenting the concept through context description. The learning multimedia is used in all STL learning phases. It can be used by teacher to deliver the material in almost all phases of learning, while student use it when teacher give them instruction.
