An introduction to Perovskites | Perovskite-Info

Perovskite is a calcium titanium oxide mineral, with the chemical formula CaTiO3. The mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792–1856). This creates an opportunity in pairing them up with low bandgap photovoltaic technology, which will result in

Introduction to Photovoltaic Solar Energy | SpringerLink

Solar cell or photovoltaic cell is the structure block of the photovoltaic system. Several solar cells are wired together in parallel or sequence to form modules whereas some sections are combined to form a PV panel and a number of panels are related to one another in sequence and parallel to form an array (Fig. 3.18 ).

Structural diversity in transition metal-doped titanium oxo-alkoxy

Since the discovery of its photocatalytic properties, titanium dioxide has remained one of the most popular and widely used metal oxide photocatalysts. Its major drawback, however, lies in the narrow region (UV) of sunlight necessary to produce reactive oxygen species. This have been countered by sensitizing with organic dyes to red-shift the absorption spectrum
