“…However, these laboratory based fabrication methods for perovskite films are not well-matched with a low costing, roll to roll process that is typical for large scale manufacture. 18 A solution would be to develop a one-step spray coating approach, which has already been successfully exploited for a range of electronic devices such as light emitting diodes, 19 photo-detectors, 20 field effect transistors 21 and also photovoltaics. 22,23 However, challenges still exist to deploy spray coating for perovskite photovoltaics as for instance thin layers as required for optimal device performance are still difficult to achieve by spray.…”

aIn recent years there has been significant research into organic-inorganic halide perovskites for photovoltaic applications and has resulted in power conversion efficiencies greater than 20%. A number of deposition techniques have been utilized to produce high quality perovskite films including thermal evaporation, single and two-step spin coating and vapor assisted processes. However, these laboratory based fabrication methods are not well matched with low costing, roll to roll processing that is associated with large scale manufacture. In this work we use a low costing and rapid spray coating technique to fabricate solution processed MAPbI 3 films with controlled film thickness achieved through modifying concentration/spray volume. Investigation into the chemical composition and film morphology showed differing surface chemistries for the different film thicknesses, altering the surface morphology from large micro grained structures to small distorted grain arrangements. We have then implemented spray deposited films into solar devices (ITO/TiO 2 /MAPbI 3 /Au) and have studied the current density-voltage (JV) characteristics including light soaking effects. Through optimizing the absorber thickness the short-circuit current density is increased from 4.9 mA cm À2 to 22.3 mA cm À2, increasing overall power conversion efficiency by a factor 45. Investigation into the performance of devices under continued illumination showed an inverse relationship existed between low efficiency (thick) MAPbI 3 films and high efficiency (thin) MAPbI 3 films, where the former displayed large increases in overall performance compared to the rapid degradation in the latter. We attribute device instabilities to the increase in defect density as a consequence of the spray-induced surface chemistry, leading to trap assisted recombination at the back electrode.

“…We have shown that V OC could be improved to up to ≈1.3 V if the trap density was reduced to N t < 10 13 cm −3 . The fill factor (FF) has been reported to be in the range of 0.70–0.85 for efficient perovskite solar cells . However, most of them are still dependent on the voltage sweep direction because of J–V hysteresis.…”

In this study, the origin of fill factor (FF) in lead-halide perovskite solar cells is discussed based on different thickness of 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9-spirobifluorene (spiro-OMeTAD) as a hole-transporting layer (HTL). As the thickness of HTL is decreased, the FF increases and hence the photovoltaic performance is also improved. This is mainly ascribed to the reduced series resistance with decreasing HTL thickness. Such improvement in FF is examined on the basis of an empirical equation for FF with the diode and photovoltaic parameters. As a result, the thickness-dependent FF can be well explained by this equation.The potential improvements in FF and PCE are further discussed on the basis of the empirical equation.3

“…The n -i-p is also called as normal device structure and p-i-n structure is also called as inverted device structure. Simply, depending on the position of the ETM and HTM, the device structure varies [70,[72][73][74]. The details about the different electron and hole transporting layers are discussed in the forthcoming section.…”

Organic-inorganic hybrid perovskite solar cells (PSCs) have emerged as a new class of optoelectronic semiconductors that revolutionized the photovoltaic research in the recent years. The perovskite solar cells present numerous advantages include unique electronic structure, bandgap tunability, superior charge transport properties, facile processing, and low cost. Perovskite solar cells have demonstrated unprecedented progress in efficiency and its architecture evolved over the period of the last 5-6 years, achieving a high power conversion efficiency of about 22% in 2016, serving as a promising candidate with the potential to replace the existing commercial PV technologies. This review discusses the progress of perovskite solar cells focusing on aspects such as superior electronic properties and unique features of halide perovskite materials compared to that of conventional light absorbing semiconductors. The review also presents a brief overview of device architectures, fabrication methods, and interface engineering of perovskite solar cells. The last part of the review elaborates on the major challenges such as hysteresis and stability issues in perovskite solar cells that serve as a bottleneck for successful commercialization of this promising PV technology.
