Heterojunction solar cell based on metal oxides achieves 23.3% efficiency

Scientists at Delft University of Technology in the Netherlands have developed an n-type silicon heterojunction solar cell using transition metal oxide (TMO) thin films. The TMO materials, specifically polytungstate (WOx) and vanadium suboxide (V2Ox), were applied through interface engineering methods to enhance the cell's performance by controlling oxygen content in the films and mitigating detrimental interface reactions. The WOx-based cell achieved a power conversion efficiency of 23.30% while the V2Ox-based device reached 22.04%.
