文摘

Both heat and light contribute to 31–66% initial burn-in degradation. First reported TS80 lifetime (3450–5600 h) of high PCE SM BHJ solar cells. Post burn-in lifetime of SM BHJ is governed by thermal degradation. Higher crystallinity active layer solar cells have less photo burn-in. Larger molecule weight donor contributes to higher thermal stability.
