Sensitized Solar Cells

Dye-sensitized Solar Cells (DSCs) Have Received Widespread Attention Owing to their Low Cost, Easy Fabrication, and Relatively High Solar-to-electricity Conversion Efficiency. Based on the Tio2 Electrode, Ruthenium Complex Dye, Liquid Electrolyte, and Pt Counter Electrode, Dscs Have Already Exhibited an Efficiency above 11% and Offer an Appealing Alternative to Conventional Solar Cells. however, until now the Commercial and Well Known Standard Dye Is the Ruthenium Complex, Namely, Cis-bis(isothiocyanato)-bis(2,2'-bipyridyl-4,4'dicarboxylato)ruthenium(II) (N3) which Has Been Widely Used around the Word. in this Article, N3 Standard Dye Was Synthesized and Characterized by Two Synthetic Routes: Grätzel’s Protocol and a One-pot Reaction from Cheap and Easily Prepared Starting Materials.

Organic solvents used for electrolytes of dye-sensitized solar cells (DSSCs) are generally not only toxic and explosive but also prone to leakage due to volatility and low surface tension. The representative dyes of DSSCs are ruthenium-complex molecules, which are expensive and require a complicated synthesis process. In this paper, the eco-friendly DSSCs were presented based on water-based electrolytes and a commercially available organic dye. The effect of aging time after the device fabrication and the electrolyte composition on the photovoltaic performance of the eco-friendly DSSCs were investigated. Plasma treatment of TiO2 was adopted to improve the dye adsorption as well as the wettability of the water-based electrolytes on TiO2. It turned out that the plasma treatment was an effective way of improving the photovoltaic performance of the eco-friendly DSSCs by increasing the efficiency by 3.4 times. For more eco-friendly DSSCs, the organic-synthetic dye was replaced by chlorophyll extracted from spinach. With the plasma treatment, the efficiency of the eco-friendly DSSCs based on water-electrolytes and chlorophyll was comparable to those of the previously reported chlorophyll-based DSSCs with non-aqueous electrolytes.

Chlorophyll a derivatives were integrated in “all solid-state” dye sensitized solar cells (DSSCs) with a mesoporous TiO2 electrode and 2′,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene as the hole-transport material. Despite modest power conversion efficiencies (PCEs) between 0.26% and 0.55% achieved for these chlorin dyes, a systematic investigation was carried out in order to elucidate their main limitations. To provide a comprehensive understanding of the parameters (structure, nature of the anchoring group, adsorption …) and their relationship with the PCEs, density functional theory (DFT) calculations, optical and photovoltaic studies and electron paramagnetic resonance analysis exploiting the 4-carboxy-TEMPO spin probe were combined. The recombination kinetics, the frontier molecular orbitals of these DSSCs and the adsorption efficiency onto the TiO2 surface were found to be the key parameters that govern their photovoltaic response.
