Korea-based Hanwha Solutions has announced that it has come one step closer to mass-producing perovskite solar cells. Hanwha Q CELLS, the solar power business division of Hanwha Solutions, recently succeeded in developing a 6-inch solar tandem cell.
Hanwha Solutions has reportedly overcome the disadvantages of small area cells, which were a constraint on mass production of perovskite batteries, paving the way for mass production of next-generation solar cells. The company is currently working on performance improvement of the solar tandem cell, with the goal of beginning mass production of perovskite batteries in 2025. Hanwha Q CELLS said it is preparing for mass production of the tandem cells.
Most of the tandem cells being developed by major companies and organizations around the world have a small surface area (one square meter). For mass production, it is necessary to increase the area of this cell. Hanwha Q CELLS succeeded in expanding the cell area to six inches (15.24 square meters).
