“…[15][16][17][18] Particularly, the extension of the porphyrin p-system plays an important role in the enhancement of their optical properties yielding NIR absorbers. [19][20][21][22][23] One application of these materials is the production of bulk heterojunction solar cells. 24 The extension of the porphyrin p-conjugation generally increases the absorption in the Q-band region and widens the fraction of the solar spectrum that can be used for the conversion of energy.…”

“…He et al introduced the 8-hydroxylquinoline as anchoring group for porphyrins, in which N and O atoms were used to chelate to metal ions forming stable complexes (He et al, 2012a ). They further tested the adsorption ability by immersion the sensitized TiO 2 film in acetic acid solution in acetonitrile, in which TPPZn-OQ porphyrin showed much superior stability than its carboxyl acid analog (Si et al, 2014 ). Yeh and Grätzel reported porphyrins MH2 and MH3, in which hydroxyl or carboxyl acid was attached to the 2-position of the pyridine to enhance the adsorption ability (Mai et al, 2015 ).…”

Dye-sensitized solar cell (DSSC) has been attractive to scientific community due to its eco-friendliness, ease of fabrication, and vivid colorful property etc. Among various kinds of sensitizers, such as metal-free organic molecules, metal-complex, natural dyes etc., porphyrin is one of the most promising sensitizers for DSSC. The first application of porphyrin for sensitization of nanocrystaline TiO2 can be traced back to 1993 by using [tetrakis(4-carboxyphenyl) porphyrinato] zinc(II) with an overall conversion efficiency of 2.6%. After 10 years efforts, Officer and Grätzel improved this value to 7.1%. Later in 2009, by constructing porphyrin sensitizer with an arylamine as donor and a benzoic acid as acceptor, Diau and Yeh demonstrated that this donor-acceptor framwork porphyrins could attain remarkable photovoltaic performance. Now the highest efficiencies of DSSC are dominated by donor-acceptor porphyrins, reaching remarkable values around 13.0% with cobalt-based electrolytes. This achievement is largely contributed by the structural development of donor and acceptor groups within push-pull framwork. In this review, we summarized and discussed the developement of donor-acceptor porphyrin sensitizers and their applications in DSSC. A dicussion of the correlation between molecular structure and the spectral and photovoltaic properties is the major target of this review. Deeply dicussion of the substitution group, especially on porphyrin's meso-position were presented. Furthermore, the limitations of DSSC for commercialization, such as the long-term stability, sophisticated synthesis procedures for high efficiency dye etc., have also been discussed.

“…However, it was demonstrated that COOH dissociates on the TiO 2 surface after long irradiation times, increasing the liability of these molecules [47]. Because of this, it is important the development of novel anchoring units that are able to bind strongly to the TiO 2 [48][49][50]. Insuasty et al [36] Reported the synthesis of push-pull systems covalently attached to the 2-(1,1-dicyanomethylene) rhodanine (DCRD) that can also work as an efficient anchoring unit to the TiO 2 without the presence of the COOH group [37].…”

Due to the negative impact on the environmental using fossil fuels, photovoltaic (PV) technology has become a new alternative for renewable energy in the last two decades. Although inorganic solar cells have dominated in the PV field, metal-free organic compounds have introduced a new challenge because of their great properties that include: i) high light-harvesting ranges, ii) optical-and electrochemical properties can be easily tuned by decorating their structure through a several synthetic approaches, and iii) their technology has high flexibility and low manufacturing cost. In this short review, we depicted our work in the synthesis of organic compounds and their applications in the PV field, specifically in bulk heterojunction solar cells (BHJSCs), dyesensitized solar cells (DSSCs) and organic-inorganic perovskites solar cells (O-IPSCs).
