光伏能量转换效率的限制通常是使用详细平衡法来制定的。肖克利和奎瑟。一个关键的潜在假设是不变性：在时间反转时；支撑详细的平衡本身。最近对紧凑型、分层的、时间不对称的磁光器件的提议使它们的常规实施成为可能。结果表明，这种时间不对称性可以改变Shockley-Queisser方法中假定的太阳能电池发射和吸收之间的关系：允许超过普遍接受的光伏性能极限。
Limits upon photovoltaic energy conversion efficiency generally are formulated using the detailed balance approach.. of Shockley and Queisser. One key underlying assumption is invariance :upon time reversal; underpinning detailed balance itself. Recent proposals for compact.; layered, time-asymmetrical, magneto-optical devices make their routine implementation likely. It is shown that such time asymmetry can alter the relationship between solar cell emission and absorption assumed in the Shockley-Queisser approach, :allowing generally accepted :photovoltaic performance limits to be exceeded.
