Lead-free Perovskite Solar Cells
The research paper published in Nature Energy, Enhanced Stability and Efficiency in Hole-Transport Layer Free CsSnI3 Perovskite Photovoltaics, tackles how solar cells can be enveloped by tin-based instead of lead-based perovskite photovoltaic cells. This breakthrough research by Dr. Ross Hatton, Professor Richard Walton, Dr. Marc Walker and PhD student Kenny Marshall from the University of Warwick found a new alternative of perovskite solar cells that can be cheaper and more environmental friendly.Perovskite solar cells are made of thin and light flexible components that could be more usable than prevailing silicon technology. The most efficient sunlight-to-energy conversion perovskite solar cells contain lead. According to the UK scientists, the use of lead material becomes a barrier for commercialization because of its toxicity components. To overcome the barrier, the research team has developed a way to manufacture a tin-based rather than lead-based perovskite solar cells that turrns out to be more stable and commercially feasible for a wide range uses in products such as laptops, computers, and vehicles. The research team also showed the possibility of simplifying the device structure without diminishing its performance, making a vital advantage of much cheaper and easier future fabrication cost.nDr. Hatton mentions the sense of urgency to develop new solar technologies to address problems such as humanity’s dependency on fossil fuels resulting to climate change It is hoped that this work will help to stimulate an intensive international research effort into lead-free perovskite solar cells, like that which has resulted in the astonishingly rapid advancement of lead perovskite solar cells.nWant to know more about this awesome device?
