Kesterite Solar Cells

Abstract

The research on photovoltaics is focusing on developing solutions that involve the employment of abundant and non-toxic raw materials, along with simple production processes. Among the light-absorbing materials, which use earth-abundant elements and are easily processable, there is the class of kesterite compounds. The efficiency record has been stopped at 12.6% for five years, but the research is fervent and dedicated to solving the limitations that make the device immature for the commercial market. The involvement and collaboration of researchers from multiple disciplinary areas are feeding the knowledge of this class of materials, promoting it as a possible next leader of the photovoltaic market.
