Perovskite solar cells can be damaged when partially shaded, owing to currents flowing in reverse. Two research groups have now increased the breakdown voltage of the perovskite devices (the tolerance against this reverse bias degradation), one by using multilayer charge-selective contact stacks on the cathode side, and the other by using relatively thick, dense electrodes on the anode side.

提高故障标准


由于电流反向流动，钙钛矿太阳能电池在部分遮蔽时可能会损坏。两个研究小组现在已经提高了钙钛矿器件的击穿电压（对这种反向偏置退化的容忍度），一个通过在阴极侧使用多层电荷选择性触点堆栈，另一个通过在阳极侧使用相对较厚、致密的电极。
