“…Due to these difficulties, previous efforts by a number of researchers have focused on modifying the inorganic metal oxide surface by binding to it various organic molecules and ruthenium-based dyes that, in combination with hole transporting conjugated polymers, result in photovoltaic devices with photoconversion efficiencies well below 1%. [23][24][25][26][27][28][29][30][31] Here, we successfully demonstrate a device structure comprised of TiO 2 nanotube arrays/organicdye/P3HT, with the vertically oriented TiO 2 nanotube arrays of small pore size providing a large interfacial surface area for dye adsorption and a large interfacial area between the organic dye monolayer and the P3HT. The successful infiltration of P3HT into the nanotube arrays is demonstrated.…”

The development of high-efficiency solid-state excitonic photovoltaic solar cells compatible with solution processing techniques is a research area of intense interest, with the poor optical harvesting in the red and near-IR (NIR) portion of the solar spectrum a significant limitation to device performance. Herein we present a solid-state solar cell design, consisting of TiO 2 nanotube arrays vertically oriented from the FTOcoated glass substrate, sensitized with unsymmetrical squaraine dye (SQ-1) that absorbs in the red and NIR portion of solar spectrum, and which are uniformly infiltrated with p-type regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT) that absorbs higher energy photons. Our solidstate solar cells exhibit broad, near-UV to NIR, spectral response with external quantum yields of up to 65%. Under UV filtered AM 1.5G of 90 mW/cm 2 intensity we achieve typical device photoconversion efficiencies of 3.2%, with champion device efficiencies of 3.8%.The best performing bulk heterojunction solar cells (η ∼ 6%) employ an optimized blend of a polymeric donor and a fullerene acceptor. 1,2 The fullerene acceptor absorbs very little light and is primarily used in blends to provide an efficient interface for exciton dissociation. Various efforts toward efficiency improvement in these devices are directed toward the development of low band gap polymers to absorb a broad swathe of the solar spectrum, 3-6 lowering the molecular energy levels of the semiconducting polymer to enhance the open circuit voltage of the organic solar cells, 1,7 and the control of the blended film morphology for enhanced exciton harvesting. [8][9][10][11][12] In the best performing solid-state dyesensitized solar cells (SS-DSSCs), η ∼ 5%, the only photon absorber is a dye, while the electron and hole transport functions are performed, respectively, by a disordered nanoparticulate TiO 2 network and a transparent small molecule spiro-OMeTAD. [13][14][15][16] To achieve higher efficiency devices, research efforts have focused on improved porefilling by the hole transporter, the use of higher mobility hole transporters and the synthesis of dyes with a broader and more-intense absorption spectrum.Red/NIR radiation (650-1000 nm) accounts for approximately 33% of the solar energy arriving at the surface of the Earth, while UV-visible radiation (350-650 nm) accounts for about 40%. Hence a key issue toward achieving higher efficiency organic solar cells is in the development of red and NIR absorbing molecules to utilize more of the solar spectrum. As an approach for efficiently utilizing visible to NIR solar radiation, herein we describe an inorganic-organic hybrid solar cell, see Figure 1a, where electron transporting TiO 2 nanotube arrays, sensitized with red and NIR light absorbing organic dye, are used in combination with hole transporting and visible light absorbing regioregular P3HT. [17][18][19] It should be noted that this low band gap organic dye should not block transmission of the high-energy photons of near-UV-visible range pa...

“…Solar conversion efficiency was doubled under 190 mW/cm 2 solar emission of xenon arc lamp. Icli et al has shown that peryleneimide dyes, that are known to form layered selfassembled in - stacks, [49,50] give poor photo-electron injection in dye-sensitized solar cells. Presence of branched long alkyl chains prevents the self-assembled in - stacking and as a result solar conversion efficiencies enhances [51].…”

Tang's introduction of two-layer organic photovoltaic cell, fabricated from copper phthalocyanine and a perylene tetracarboxylic solid thin films, has opened the novel era of organic solar cells. A power conversion efficiency of about 1% has been achieved under simulated 1.5 AM sun illumination.Then Graetzel cell has been developed in 1991. And afterwards solid state dye sensitized solar cells have been developed. And new era has opened for photovoltaic production technologies. This review summarizes working principle of photovoltaic technologies.

Similar Device Architectures for Inverted Organic Solar Cell and Laminated Solid-State Dye-Sensitized Solar Cells

Here, we examine the device architecture of two different types of solar cells mainly inverted organic solar cells and solid state dye-sensitized solar cells (DSSCs) that use organic materials as hole transportation. The inverted organic solar cells structure is dominated by work on titanium dioxide (TiO 2 ) and zinc oxide (ZnO). These layers are sensitized with dye in solid state DSSCs. Because of the similar device architecture, it becomes possible to fabricate laminated solid-state DSSCs. The performance of the device was improved by varying the top metal electrode. In laminated solid-state DSSC, we expect that excited dye molecules inject electron into the conduction band of nanocrystalline TiO 2 layer, whereas P3HT provides efficient hole transportation. These solar cells are promising for future energy source as they are cheaper, light weight, flexible and made into large areas, which are showing growing importance.
