Efforts are currently on going on the physics of photo electrics in methyl ammonium lead halide perovskites to unveil the secret of its success in photovoltaics. Since carrier concentration depends on impurity, temperature and other parameters of a semico... see more

We report the growth and characterization of different bulk single crystals of organo lead mixed halide perovskites CH3NH3PbI3-xBrx by two different crystal growth approaches: (i)anti-solvent diffusion, and (ii) inverse temperature crystallization. In ord... see more

Organometal halide perovskite materials have shown high potential as light absorbers for photovoltaic applications. In this work, perovskite planar solar cells were fabricated on corning substrates with the structure as follows: the first layer made of ta... see more

The morphology control of CH3NH3PbI3 (MAPbI3) thin-film is crucial for the high-efficiency perovskite solar cells, especially for their planar structure devices. Here, a feasible and effective post-treatment method is presented to improve the quality of M... see more

Bismuth ferrite (BiFeO3) thin films were prepared by a spin-coating method. Crystal structure and optical properties of the BiFeO3 films were evaluated using X-ray diffraction. The lattice constants, crystallite size, and energy gap of BiFeO3 films depend... see more

Fabrication and characterization of CH3NH3PbI3-x-yBrxCly perovskite solar cells using mesoporous TiO2 as electron transporting layer and 2,2',7,7'-tetrakis-(N,N-di-4-methoxyphenylamino)-9,9'-spirobifluorene as a hole-transporting layer (HTL) were performe... see more

In this research paper, a HTM-free perovskite solar cell (PSC) structure with Titanium (TiO2), methyl ammonium lead triiodide (CH3NH3PbI3) and platinum (pt) as electron transport material (ETM), photon harvester and metal back contact is proposed. Solar C... see more

Perovskite Solar Cells (PSC), with the efficiency of more than 22%, has shown promising prospects for the future of environmentally friendly technology. However, low stability on humidity is a major problem limiting the commercialization of PSC. The perov... see more

Methyl-ammonium lead tri iodide (CH3NH3PbI3) perovskite thin films have been prepared by solution processing. Thin film after deposited in the laboratory ambient conditions by drop casting, it prepared by two step method PbI2 and CH3NH3I at the glass subs... see more
