Abstract

, and consequently an overall solar energy conversion efficiency of 4.1%. TiO 2 films and gels were characterized by FE-SEM and FT-IR, and the assembled DSSCs by photocurrent density-voltage and incident photon-to-current conversion efficiency measurements.

Review on polymer electrolyte in dye-sensitized solar cells (DSSCs)

“…They consist of a variety of classical polymeric materials from synthetics polymer and its blends to bio-based polymer. Namely, PEO (Ren et al, 2002), poly (methyl methacrylate) (PMMA) (Lee et al, 2010e;Yang et al, 2008), polyethylene glycol (PEG) (Joseph et al, 2006), poly(ethylene glycol) methyl ether methacrylate (PEGMA) (Bella et al, 2013a(Bella et al, , 2013b, polyacrylonitrile (PAN) (Taslim et al, 2010;Rika et al, 2009;Rahman et al, 2010), poly(vinyl chloride) (PVC) (Rahman et al, 2004(Rahman et al, , 2007, and poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) Lee et al, 2008b;Priya et al, 2008;Noor et al, 2014). To date, polysaccharides and modified polysaccharides based materials such as chitosan (Buraidah et al, 2010), cellulose (Rudhziah et al, 2015) and carrageenan (Bella et al, 2015) received the attention due to their higher ionic conductivities at room temperature.…”

A Thermoplastic Gel Electrolyte for Stable Quasi‐Solid‐State Dye‐Sensitized Solar Cells

“…The first quasi-solid-state DSSC was constructed by integrating polyacrylonitrile, ethylene carbonate, propylene carbonate (PC), acetonitrile, and NaI in 1995; [28] however, the photoelectric efficiency of the cell was only 4.4 %. In subsequent efforts, many different polymer gel electrolytes have been used to construct quasi-solid-state DSSCs, [8,[11][12][13][14][29][30][31][32][33][34][35][36][37][38] and Dye-sensitized solar cells (DSSCs) are receiving considerable attention as low-cost alternatives to conventional solar cells. In DSSCs based on liquid electrolytes, a photoelectric efficiency of 11 % has been achieved, but potential problems in sealing the cells and the low long-term stability of these systems have impeded their practical use.…”

PENGGUNAAN EKSTRAK ANTOSIANIN KOL MERAH SEBAGAI FOTOSENSITIZER PADA SEL SURYA TiO2 NANOKRISTAL TERSENSITISASI DYE

“…Oleh karena itu, akhir-akhir ini pengembangan penelitian sel surya fotoelektrokimia ini diarahkan pada penggunaan elektrolit padat untuk mengurangi degradasi dan kebocoran elektrolit yang dapat meningkatkan stabilitas sel, misalnya elektrolit berbasis polimer yang mengandung kopel redoks [2,3,[12][13][14] atau berbasis bahan organik atau anorganik sebagai konduktor hole [4,15,16]. ) sebagai pengganti elektrolit cair.…”

“…sebagai pengganti elektrolit cair. Penggunaan matriks polimer bagi kopel redoks sebagai elektrolit padat pada sel surya tersensitasi dye telah dilakukan oleh beberapa kelompok peneliti, diantaranya menggunakan PEO (polyethylene oxide) [3,17], PAN (polyacrylonitrile) [13] dan PEG [14]. Namun, sejauh ini belum ada yang menggabungkan penggunaan dye alami dan elektrolit padat berbasis gel polimer secara bersamaan pada sistem sel surya fotoelektrokimia tersensitisasi dye.…”

“…[7]. Sedangkan untuk sel surya tersensitisasi dye sintesis dengan elektrolit padat berbasis polimer telah dicapai efisiensi konversi energi hingga 4% [2,14]. Rendahnya nilai efisiensi konversi terutama akibat rendahnya arus yang dihasilkan, salah satunya akibat resitansi sistem sel surya yang terdiri dari lapisan elektroda semikonduktor TiO 2 dan elektrolit polimer yang sangat besar.…”
