“…Organic-inorganic hybrid heterojunction solar cells containing the CH 3 NH 3 PbI 3 perovskite compound have the great advantage of fabricating on mesoporous TiO 2 as the electronic transporting layer and 2,2 1 ,7,7 1 -tetrakis-(N,N-di-4-methoxyphenylamino)-9,9 1 -spirobifluorene (spiro-OMeTAD) as the hole-transporting layer (HTL) [8][9][10]. The effects of halogen doping and HTL on photovoltaic properties and microstructure on organic-inorganic hybrid heterojunction solar cells using the perovskite compound have been studied for improving photovoltaic performance and optical properties.…”

Fabrication and characterization of CH 3 NH 3 PbI 3´x´y Br x Cl y perovskite solar cells using mesoporous TiO 2 as electron transporting layer and 2,2 1 ,7,7 1 -tetrakis-(N,N-di-4-methoxypheny lamino)-9,9 1 -spirobifluorene as a hole-transporting layer (HTL) were performed. The purpose of the present study is to investigate role of halogen doping using iodine (I), bromine (Br) and chlorine (Cl) compounds as dopant on the photovoltaic performance and microstructures of CH 3 NH 3 PbI 3´x´y Br x Cl y perovskite solar cells. The X-ray diffraction identified a slight decrease of crystal spacing in the perovskite crystal structure doped with a small amount of I, Br, and Cl in the perovskite compounds. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) showed the perovskite crystal behavior depended on molar ratio of halogen of Pb, I, Br and Cl. Incorporation of the halogen doping into the perovskite crystal structure improved photo generation, carrier diffusion without carrier recombination in the perovskite layer and optimization of electronic structure related with the photovoltaic parameters of open-circuit voltage, short-circuit current density and conversion efficiency. The energy diagram and photovoltaic mechanisms of the perovskite solar cells were discussed in the context of the experimental results.

“…It had been used for perovskite solar cells in 2012 [35] as an evaporated hole transporting layer, owing to the high charge mobility (up to 0.02 cm 2¨V´1¨s´1 ) associated with its high crystallinity. However, as it forms a large π-conjugated system, it remains difficult to dissolve in common organic solvents.…”

Hybrid organometal halide perovskites have attracted much attention these past four years as the new active layer for photovoltaic applications. Researches are now intensively focused on the stability issues of these solar cells, the process of fabrication and the design of innovative materials to produce efficient perovskite devices. In this review, we highlight the recent progress demonstrated in 2015 in the design of new π-conjugated organic materials used as hole transporters in such solar cells. Indeed, several of these "synthetic metals" have been proposed to play this role during the last few years, in an attempt to replace the conventional 2,2 1 ,7,7 1 -tetrakis-(N,N-di-4-methoxyphenylamino)-9,9 1 -spirobifluorene (Spiro-OMeTAD) reference. Organic compounds have the benefits of low production costs and the abundance of raw materials, but they are also crucial components in order to address some of the stability issues usually encountered by this type of technology. We especially point out the main design rules to reach high efficiencies.

“…Organic-inorganic hybrid heterojunction solar cells containing the CH3NH3PbI3 perovskite compound have a great advantage in terms of fabrication using mesoporous TiO2 as the electronic transporting layer and spirobifluorence as the hole-transporting layer. Fabrication and characterization of organic-inorganic hybrid heterojunction solar cells using the perovskite compound with semiconducting material as the hole-conductors have been reported for improving performance of photovoltaic and optical properties [8][9][10]. Especially, influence of halogen doping on bromide, iodide and chloride halide perovskite structure in the hybrid solar cells have been characterized for achieving a high conversion efficiency [11][12][13].…”
