Lithium-doping inverts the nanoscale electric field at the grain boundaries in Cu sub(2)ZnSn(S,Se) sub(4) and increases photovoltaic efficiency

Passive grain boundaries (GBs) are essential for polycrystalline solar cells to reach high efficiency. However, the GBs in Cu sub(2)ZnSn(S,Se) sub(4) have less favorable defect chemistry compared to CuInGaSe sub(2). Here, using scanning probe microscopy we show that lithium doping of Cu sub(2)ZnSn(S...
