A researcher in Haryana has revealed a revolutionary manufacturing process for silicon solar cells that has the potential to drastically reduce the price of these cells. Swasti Bhatia, a PhD student at IIT Bombay at the time, demonstrated a silicon solar cell with 12% efficiency, fabricated entirely at below 100C. By using new, non-toxic materials such as TiO2, these low-temperature solar cells replace predominantly high-temperature processes that also use harmful gases such as phosphine.
