Abstract:
The worldwide increase in energy consumption has motivated scientists to explore
the potential of solar energy. At present, solar energy harvesting is carried out mostly
(more than 90%) by the inorganic crystalline silicon (Si) solar cells. Moreover, Si-based
solar cells are now approaching their maximum theoretical limiting efficiency of
~29.43%. The latest advancements in technology and materials have led to the
development of novel photosensitive materials that enabled the fabrication of low cost
and highly efficient photovoltaic devices. The state of the art growth in various
perovskite materials like inorganic (CsPbX3: X=I, Cl, Br) and hybrid (ABX3; A=
organic compound, B= inorganic compound, and X= halides) have attracted huge
interest among the researchers. Recently, methylammonium lead halides
(CH3NH3PbX3) have shown highly encouraging photosensitive for photovoltaic
application, which gained immense research attention since its discovery and has
boosted hopes for new photovoltaic technologies.
