Abstract:
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.
