“…According to the order of preparation, the planar structure can be categorized into two types: regular (n-i-p) and inverted (p-i-n) [4]. For inverted planar hetero-junction, PSCs are, in general, based upon the structure of (fluorine-doped tin oxide (FTO)/hole transport layer (HTL)/perovskite layer/electron transport layer (ELT)/metal electrode) have attracted significant attention because of the simple processing procedure, little hysteresis and high efficiency device design [5,6]. A transparent electrode is necessary for the solar cells as it permits the arriving light to attain the photoactive layer.…”

“…The transparent conductive oxides (TCO) like FTO is used well suited for this purpose due to its transparent and conductive nature [7]. Poly(3,4 ethylenedioxythiophene): polystyrene sulfonate (PEDOT: PSS) organic material has been used to as HTL owing to high transparency and conductivity (10 −4 to 10 −3 s/ cm), high mechanical flexibility [8] and fabrication at low temperature [4,5]. While, the inorganic methyl ammonium lead triiodide perovskite material (MAPbI 3 ) was used as a light-harvesting layer in solar cells owing to the unique optoelectronic characteristics, like (proper straight bandgap, ambipolarity [9], high mobility of charge carrier, the high coefficient of absorption, a steep edge of absorption, the long length of diffusion and the unique tolerance to the structural defects) [2,10], easy synthesis, and low cost [11].…”

Silicon, polymer and dye sensitized have been increasing rapidly in thin film of solar cells. Recently, perovskite is proposed as alternative material in the fabrication of solar cells. In this study, methyl ammonium lead triiodide (MAPbI 3 , CH 3 NH 3 PbI 3) perovskite thin film was prepared by two-step process of spin coating. The preparation process of thin film is summarized by reaction between the methyl ammonium iodide (CH 3 NH 3 I) and lead iodide (PbI 2). The absorbent layer of the prepared perovskite solar cell is based on the MAPbI 3 (CH 3 NH 3 PbI 3) thin film. The conversion efficiency of p-n silicon solar cells can be improved by preparing tandem solar cells. The X-ray diffraction result of the MAPbI 3 perovskite film manifested that it is polycrystalline with tetragonal system having a crystallite size of about 40 nm. The absorption spectrum of perovskite film was recorded by Ultra Violet-Visible spectrophotometer. The energy band gap of the MAPbI 3 film calculated by Tauc's formula was ~ 1.51 eV. The field emission scanning electron microscope image of the MAPbI 3 film surface elucidated a cubic-like crystal structure and other irregular structures also. The atomic force microscope image and the distribution chart of the grains of the film displayed that the grain size was ~ 58.7 nm. The results demonstrated that the conversion efficiency for silicon, perovskite and tandem (silicon/perovskite) solar cells are 3%, 4.83% and 7.42%, respectively.

“…Nevertheless, the values obtained by Tauc plot suggest that the CBM is placed above the LUMO of the PBDD4T-2F for all the compositions. Finally, we can assert that the CuCrO 2 thin films possess well-suited energetic levels to efficiently working as HTL in PBDD4T-2F:PC 70 BM based devices, while preserving ohmic contacts with the ITO electrode, thus representing a valid alternative to PEDOT:PSS [ 60 ]. The values of the HOMO and LUMO for ITO, PBDD4T-2F, PC 70 BM, LiF, and Al were obtained from literature [ 61 , 62 , 63 ].…”

The performance and stability in atmospheric conditions of organic photovoltaic devices can be improved by the integration of stable and efficient photoactive materials as substituent of the chemically unstable poly (3,4-ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS), generally used as organic hole transport layer. Promising candidates are p-type transparent conductive oxides, which combine good optoelectronic and a higher mechanical and chemical stability than the organic counterpart. In this work, we synthesize Cu-rich CuCrO2 thin films by aerosol-assisted chemical vapour deposition as an efficient alternative to PEDOT:PSS. The effect of stoichiometry on the structural, electrical, and optical properties was analysed to find a good compromise between transparency, resistivity, and energy bands alignment, to maximize the photovoltaic performances., Average transmittance and bandgap are reduced when increasing the Cu content in these out of stoichiometry CuCrO2 films. The lowest electrical resistivity is found for samples synthesized from a solution composition in the 60–70% range. The optimal starting solution composition was found at 65% of Cu cationic ratio corresponding to a singular point in Hackee’s figure of merit of 1 × 10−7 Ω−1. PBDD4T-2F:PC70BM organic solar cells were fabricated by integrating CuCrO2 films grown from a solution composition ranging between 40% to 100% of Cu as hole transport layers. The solar cells integrating a film grown with a Cu solution composition of 65% achieved a power conversion efficiency as high as 3.1%, representing the best trade-off of the optoelectronic properties among the studied candidates. Additionally, despite the efficiencies achieved from CuCrO2-based organic solar cells are still inferior to the PEDOT:PSS counterpart, we demonstrated a significant enhancement of the lifetime in atmospheric conditions of optimal oxides-based organic photovoltaic devices.

“…polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), which registered low PCEs [5,13,73,76,108]. Moreover, the need for improved stability, cost-effectiveness and efficiency, have directed researchers to rethink the architecture and formulation of perovskite devices, by application of various organic composites and co-polymers, such as PCBM (phenyl-C61-butyric acid methyl ester), P3HT (poly(3-hexylthiophene) and PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrenesulfonate) [109,110], different carbon allotropes (carbon nanotubes, graphene and fullerene) [109,111,112], and alternative metal oxides (Al 2 O 3 , ZnO, SnO 2 , NiO x ) [113][114][115][116][117][118]. Figure 2a displays the typical structure of direct stacked (n-i-p) architecture of a standard thin film perovskite solar cell and the arrangement of molecules in a single perovskite unit.…”

Perovskite-based solar cells with high power conversion efficiencies (PCEs) are currently being demonstrated in solid-state device designs. Their elevated performances can possibly be attained with different non-standard geometries, for example, the fiber-shaped perovskite solar cells, in the light of careful design and engineering. Fiber-shaped solar cells are promising in smart textiles energy harvesting towards next-generation electronic applications and devices. They can be made with facile process and at low cost. Recently, fiber-shaped perovskite solar devices have been reported, particularly with the focus on the proof-of-concept in such non-traditional architectures. In this line, there are so many technical aspects which need to be addressed, if these photovoltaic (PV) cells are to be industrialized and produced massively. Herein, a well-organized and comprehensive discussion about the reported devices in this arena is presented. The challenges that need to be addressed, the possible solutions and the probable applications of these PV cells are also discussed. More still, the perovskite fiber-shaped PV cells with other fiber PV devices reported in literature in terms of their scope, characteristic designs, performances, and other technical considerations have been summarised.
