“…Symmetric cells composed of our electrolyte sandwiched between two Pt based counter electrodes were fabricated and EIS measurements were performed. Symmetric cells such as this allow evaluation of the processes occurring at the Pt/electrolyte interface (Liberatore et al, 2009;Meng et al, 2014). The EIS Nyquist and Bode plots of the cells fabricated with the SWCNT and hybrid (SWCNT-graphene) electrolytes are shown in Fig.…”

AbstractIn this study, we report improved power conversion efficiencies of various carbon based quasi-solid state electrolytes/DSSCs by optimising the thickness of TiO 2 layer, incorporation of TiO 2 scattering layer and application of dense compact surface layers of TiO 2 on working electrodes. Single wall carbon nanotube (SWCNT) based quasi-solid state electrolytes showed increased power conversion efficiencies from 1.43 % to 3.49 %. For the mixture of graphene and SWCNTs the power conversion efficiencies improved from 2.50 % to 2.93 %.However, graphene based quasi-solid state electrolytes displayed small decreases in power conversion efficiencies from 2.10 % to 1.96 % due to the more viscous nature of this electrolyte. Electrochemical Impedance Spectroscopy (EIS) demonstrated that the addition of these various carbon based nanomaterials into PMII significantly decreases the charge transfer resistance at the counter electrode and hence the much better performance obtained with carbon based quasi-solid state electrolytes compared to pure PMII based DSSCs.

“…The SSC operation principle mimics photosynthesis as it is kinetically controlled rather than field dependent. A SSC device consists of a semiconductor, preferably TiO 2 , coated electrode with a monolayer of dye molecules or other sensitizers like quantum dots 17 adsorbed to the TiO 2 surface. The sensitizer absorbs photons from incoming sunlight and gets energetically excited.…”

Abstract. This general article is based on the inaugural talk delivered at the opening of OMTAT 2013 conference. It notes that the integration of renewable energy sources into living and transport sectors presents a daunting task, still. In spite of the fact that the earth and its atmosphere continually receive 1.7 × 10 17 watts of radiation from the sun, in the portfolio of sustainable and environment friendly energy options, which is about 16% of the world's energy consumption and mostly met by biomass, only a paltry 0.04% is accredited to solar. First and second generation solar cells offer mature technologies for applications. The most important difficulty with regards to integration with structures is not only the additional cost, but also the lack of sufficient knowledge in managing the available energy smartly and efficiently. The incorporation of PV as a part of building fabric greatly reduces the overall costs compared with retrofitting. BIPV (Building Integrated photovoltaic) is a critical technology for establishing aesthetically pleasing solar structures. Infusing PV and building elements is greatly simplified with some of the second generation thin film technologies now manufactured as flexible panels. The same holds true for 3 rd generation technologies under development such as, and dye-and quantum dot-sensitized solar cells. Additionally, these technologies offer transparent or translucent solar cells for incorporation into windows and skylights. This review deals with the present state of solar cell technologies suitable for BIPV and the status of BIPV applications and its future prospects.
