“…DSSCs have been much investigated and all device components have been studied and improved in turn, from the metal oxide electrode, to the organic dye to the electrolyte. Several reviews have been published on various aspects of device functions, including general trends for material and commercial developments for DSSCs,15–18 or, more specifically, concerning nanostructured metal oxides;19–22 molecular dyes;23–25 electrolytes;26 or electron dynamics and charge transport 27–30. Among all DSSC components, the nanostructured metal oxide electrode is crucial, as its morphology drives many physical processes that control the overall device performance: the light‐harvesting properties are directly dependent on the amount of interface available for dye grafting; the generation yield of free charge carriers, and especially electrons, is driven by the electronic configuration of the metal oxide; and the collected photocurrent is limited by the ability of photogenerated charges to flow in the percolating nanostructured electrode.…”

In the field of photovoltaic energy conversion, hybrid inorganic/organic devices represent promising alternatives to standard photovoltaic systems in terms of exploiting the specific features of both organic semiconductors and inorganic nanomaterials. Two main categories of hybrid solar cells coexist today, both of which make much use of metal oxide nanostructures based on titanium dioxide (TiO 2 ) and zinc oxide (ZnO) as electron transporters. These metal oxides are cheap to synthesise, are non-toxic, are biocompatible and have suitable charge transport properties, all these features being necessary to demonstrate highly efficient solar cells at low cost. Historically, the first hybrid approach developed was the dye-sensitized solar cell (DSSC) concept based on a nanostructured porous metal oxide electrode sensitized by a molecular dye. In particular, solid-state hybrid DSSCs, which reduce the complexity of cell assembly, demonstrate very promising performance today. The second hybrid approach exploits the bulk heterojunction (BHJ) concept, where conjugated polymer/metal oxide interfaces are used to generate photocurrent. In this context, we review the recent progress and new concepts in the field of hybrid solid-state DSSC and BHJ solar cells based on TiO 2 and ZnO nanostructures, incorporating dyes and conjugated polymers. We point out the specificities in common hybrid device structures and give an overview on new concepts, which couple and exploit the main advantages of both DSSC and BHJ approaches. In particular, we show that there is a trend of convergence between both DSSC and BHJ approaches into mixed concepts at the borderline which may allow in the near future the development of hybrid devices for competitive photovoltaic energy conversion.

“…[1][2][3] Organic-inorganic hybrids are one promising class of novel materials that combine organic components and inorganic nanostructures through chemical and/or physical interactions. 4 Organic films containing lead chalcogenide nanoparticles are one such hybrid material that have been the subject of intense study. 2,5,6 Lead sulfide (PbS) nanoparticles allow for a size tunable bandgap due to quantum confinement effects, have large extinction coefficients, 7 and are thus under consideration for use as the near-IR active layer in multijunction photovoltaics.…”

Semiconducting lead sulfide (PbS) nanoparticles were cluster beam deposited into evaporated quaterthiophene (4T) organic films, which in some cases were additionally modified by simultaneous 50 eV acetylene ion bombardment. Surface chemistry of these nanocomposite films was first examined using standard x-ray photoelectron spectroscopy (XPS). XPS was also used to probe photoinduced shifts in peak binding energies upon illumination with a continuous wave green laser and the magnitudes of these peak shifts were interpreted as changes in relative photoconductivity. The four types of films examined all displayed photoconductivity: 4T only, 4T with acetylene ions, 4T with PbS nanoparticles, and 4T with both PbS nanoparticles and acetylene ions. Furthermore, the ion-modified films displayed higher photoconductivity, which was consistent with enhanced bonding within the 4T organic matrix and between 4T and PbS nanoparticles. PbS nanoparticles displayed higher photoconductivity than the 4T component, regardless of ion modification.

“…Since the fill factor (FF) is inversely proportional to the product between short circuit current density and open circuit voltage [11] this parameters remain almost constant throughout this research work as reflected in Fig 5. However, In this research work the optimum energy conversion efficiency after annealing at 400°C generated its maximum value of, 0.006% (Table I), which is reasonably good when compared with some recent advanced laboratory works.…”

“…At the interface the Fermi levels of both semiconductors are the same, generating depletion region, and therefore, a charge separation [10]. When photons are absorbed in the p-type region, an electron-hole pair is created [11]. Each electron is then injected in the n-type region and the hole goes across p-type region.…”

A Titanium Dioxide-Roselle Dye sensitized solar cell with a dimension of 20 x 20 mm was fabricated using Doctor-Blade Method. Some of the samples were given annealing treatment at various temperatures of 250 0 C, 300 0 C, 350 0 C, 400 0 C and 450 0 C respectively with same annealing time of 30min. The device under test (DUT) were tested using a Kiethley 2400, source meter under A.M 1.5 (1000W/m 2 ) illumination from a Newport class A solar simulator. The results shows that at the various annealing temperatures, the open circuit voltage V oc = 0.091V, 0.79V, 0.78, 0.93 and 0.46V, the short circuit current density J sc =42µAcm -2 , 16µAcm -2 , 109µAcm -2 , 505µAcm -2 and 8µAcm -2 , the fill factor FF= 0.15, 0.06, 0.03, 0.02 and 0.14 and the energy conversion efficiency, η = 6 x10 -4 , 8 x10 -4 , 2 x10 -3 , 6 x10 -3 and 5 x10 -4 respectively. The best results of open circuit voltage V oc =0.93, short circuit current density J sc = 505µAcm -2 , fill factor FF= 0.02 and energy conversion efficiency η= 6 x10 -3 was at temperature T= 400 0 C at constant annealing time, t =30 minute compared to the other four samples annealed at temperatures 250 0 C, 300 0 C, 350 0 C and 450 0 C. These results shows that at temperature T= 400 0 C the annealing treatment shows some effects on the electrical properties of the TiO 2 -Roselle Dye Sensitized solar Cell produced.Copy Right, IJAR, 2016,.

Introduction:-A solar cell is an electronic device which convert direct solar energy into electricity using the process called photovoltaic effect. The process is achieved by shining light on the solar cell which creates an electrical current or voltage in the material that generate an electric power. Solar cell is becoming ever important as an alternative sources of energy that are both cheap, efficient and environmental friendly [1]. Compared to the fossil fuels -coal, oil, and natural gas, which were formed millions of years ago from the fossilized remains of plants and animals and are the main sources of energy today [2]. Based on the depletion of fossil fuel and the environmental hazards that it causes, the use of solar energy is certainly one of the most viable ways to solve the world's energy crisis [3]. More also, owing to the rapid consumption of conventional sources of energy through high demand despite their consequences due to pollution, solar energy is considered as promising alternative to the forecasted energy and societal challenges [4]. Renewable energy sources such as solar energy are considered as a practicable alternative because "More energy from sunlight strikes Earth per each hour than all of the energy consumed by humans in an
