Scientists Develop Double-sided Solar Cells to Increase Power Generation by an Additional 30%

Scientists at the Australian National University (ANU) used laser processing to create a more efficient solar cell and set a new world record in the process. This cell is double-sided, which means that both the front and back of the cell can generate electricity. The chief researcher Dr. Kean Chern Fong said that the so-called double-sided solar cell can easily beat the performance of single-sided silicon solar cells.
 
'We have developed a truly double-sided solar cell because it has almost symmetrical power generation capacity on both surfaces of the device. When the double-sided battery is deployed in a traditional solar power field, it absorbs direct incident light while also using ground reflection, which can increase power generation by an additional 30%. Double-sided solar cells are becoming more and more important in the launch of solar farms, and the market share is expected to exceed 50% in the next five years. Our work demonstrates the incredible capabilities of this technology,' said Dr. Fong.
 
The team used a specific laser mixing technology to make the cell. The chief researcher Dr. Marco Ernst said that laser mixing used lasers to partially increase conductivity. This was a low-cost and compatible process to improve the efficiency of the solar cell.
 
This allows the research team to achieve a front conversion efficiency of 24.3% and a back conversion efficiency of 23.4%, representing a two-sided coefficient of 96.3%. This performance represents approximately 29% of the effective power output, far exceeding the performance of the best single-sided silicon solar cell.
