Researchers have come up with a new way of making thin perovskite films for solar cells. The method forms perovskite crystals at room temperature, which could be helpful in mass production settings. The technique is especially well suited to make ultra-thin, semitransparent films, which could be used in photovoltaic windows.
The underlying mechanism behind an enigmatic process called 'singlet exciton fission,' which could enable the development of significantly more powerful solar cells, has been identified by scientists in a new study.
In the face of global climate change, increasing the use of renewable energy resources is one of the most urgent challenges facing the world. New work finds that the amount of energy that could be generated from solar equipment constructed on and around existing infrastructure in California would exceed the state's demand by up to five times.
In a scant five years of development, hybrid perovskite solar cells have attained power conversion efficiencies that took decades to achieve with the top-performing conventional materials, but scientists have lacked a clear understanding of the precise goings on at the molecular level. New findings help fill that void.
By tailoring the interface between the two sections of a solar cell, researchers have produced a high-performance solar cell from the abundant and cheap materials of copper (II) oxide and silicon.
