“…[115][116][117] However, reported PCEs of these types of hybrid devices are still very low (less than 1% [113,114,117,118] ) due to the moderate conductivity of PANI. The sole relative report with a higher PCE (2.75% [40] ) utilized composite materials by adding graphene nanoparticles (GNP) in PANI. Thus, the enhancement of conductivity is a key factor to improve the photovoltaic performance of these devices.…”

“…[39] Thus, it is important to understand the factors that limit their performance so as to give full play to the advantages of both organic and inorganic semiconductor materials. According to the available reports, the factors that limit the performance of HSCs can be attributed to 1) mediocre electrical conductivity of the polymer layer, which can lead to nonradiative recombination; [40,41] 2) interface recombination between the inorganic semiconductor layer and the organic layer; [41] and 3) light reflectivity as a common problem of planar devices.…”

The combination of III–V compound semiconductor materials and organic semiconductor materials to construct hybrid solar cells is a potential pathway to resolve the problems of conventional doped p–n junction solar cells, such as complexities in fabrication process and high costs. This review presents the recent progress of organic–inorganic hybrid solar cells based on polymers and III–V semiconductors, from materials to devices. The available growth process for planar/nanostructured III–V semiconductor materials, along with patterning and etching processes for nanostructured materials, are reviewed. As an emphasis of this review, advanced device structure designs are reviewed for facilitation of carrier collection and high efficiency, at planar structure level and nanowire structure level, respectively. Optimization pathways for efficiency enhancement are discussed with respect to polymer layers and surface/interface passivation, respectively. Finally, perspectives on the future development of such hybrid cells are presented.

This paper reports the fabrication and electrical characterization of hybrid organic-inorganic solar cell based on the deposition of polyaniline (PANI) on n-type GaAs substrate with three different crystal orientations namely Au/PANI/(100) n-GaAs/(Ni-Au), Au/PANI/(110) n-GaAs/(Ni-Au), and Au/PANI/(311)B n-GaAs/(Ni-Au) using spin coating technique. The effect of crystallographic orientation of n-GaAs on solar cell efficiency of the hybrid solar cell devices has been studied utilizing current density-voltage (J-V) measurements under illumination conditions. Additionally, the influence of planes of n-GaAs on the diode parameters of the same devices has been investigated by employing current-voltage (I-V) characteristics in the dark conditions at room temperature. The experimental observations showed that the best performance was obtained for solar cells fabricated with the structure of Au/PANI/(311)B n-GaAs/(Ni-Au). The open-circuit voltage (Voc), short circuit current density (Jsc), and solar cell efficiency () of the same device were shown the values of 342 mV, 0.294 mAcm-2, 0.0196%, respectively under illuminated condition. All the solar cell characteristics were carried out under standard AM 1.5 at room temperature. Also, diode parameters of PANI/(311)B n-GaAs heterostructures were calculated from the dark I-V measurements revealed the lower reverse saturation current (Io) of 3.0×10-9A, higher barrier height () of 0.79 eV and lower ideality factor (n) of 3.16.

“…In order to obtain thin film in either micro or nanoscale, commonly Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD) and spin-coating techniques are used [1 -3]. Spin coating is recognized as the most common technique that can be applied for the deposition of different materials in the form of solutions such as nanoparticles, polymers and biomaterials [4]. Also, it is the most convenient technique for fabricating hybrid solar with different thin film thicknesses.…”

Spin coating is a technique employed for the deposition of uniform thin films of organic materials in the range of micrometer to nanometer on flat substrates. Typically, a small amount of coating material generally as a liquid is dropped over the substrate center, which is either static or spinning at low speed. The substrate is then rotated at the desired speed and the coating material has been spread by centrifugal force. A device that is used for spin coating is termed a spin coater or just a spinner. The substrate continued to spin and the fluid spins off the boundaries of the substrate until the film is reached the required thickness. The thickness and the characteristics of coated layer (film) are depending on the number of rotations per minute (rpm) and the time of rotation. Therefore, a mathematical model is obtained to clarify the prevalent method controlling thin film fabrication. Viscosity and the concentration of (solution) spin coating material are also affecting the thickness of the substrate. This article reviews spin coating techniques including stages in the coating process such as deposition, spin-up, stable fluid outflow (spin-off), and evaporation. Additionally, the main affecting factors on the film thickness in the coating process are reviewed.
