Perovskite solar cells are gaining significant popularity across the world, thanks to their simple and cost-efficient production. Perovskite solar cells include a perovskite structured compound, which is most commonly a tin halide-based material or a hybrid organic-inorganic lead, as the active layer for light-harvesting. Perovskite materials, mainly methylammonium lead halides, are relatively cheap to manufacture and their production is quite simple. These materials, which can be easily synthesized, are viewed as the future of solar cells, globally, as their unique structure makes efficient and cheap photovoltaics possible. With the enhancement in their efficiency, as one project, supported by the European Union (EU), just did, makes them more profitable alternative source of energy.

Predominantly, two parameters, stability and efficiency, are very important for commercial application of perovskite solar cells. The EU-backed GOTSOLAR project has brought together technologists and chemists from Poland and Switzerland, who have managed to display a cell with remarkably lesser structural defects. The research team explained that the unforeseen improvements in the photovoltaic performance were observed when perovskites manufactured using mechanochemistry were utilized for the production of a common photovoltaic cell. In place of manufacturing perovskites through conventional solution methods, the team has utilized grinding method for the production of these cells. The research is at an advanced stage of mechanochemistry, which is a rapidly evolving field of science that deals with chemical reactions occurring directly among solid-phase compounds on initiation by mechanical force.
