The highest power conversion efficiencies for silicon heterojunction solar cells have been achieved on devices based on n-type doped silicon wafers, yet these wafers are usually more expensive than p-type ones. Now, researchers reduce charge recombination in the bulk of p-type silicon, demonstrating comparable efficiency to devices based on n-type silicon.

硅异质结太阳能电池的最高功率转换效率是在基于 n 型掺杂硅晶圆的器件上实现的，但这些晶圆通常比 p 型晶圆更昂贵。现在，研究人员减少了 p 型硅体中的电荷复合，证明了与基于 n 型硅的器件的效率相当。
