是有“太阳能之父”之称的Martin A Green 写的书 The third generation photovoltaics 里的一段话，我觉得逻辑上似乎有问题，他是怎么得到最后的结论的？The first and second laws of thermodynamics were succinctly stated by Rudolf Clausius in 1865: “The total energy of the universe is constant. The total entropy of the universe strives to reach a maximum” (Clausius 1865). By associating nonnegative entropy production with any energy exchange, both laws can be expressed as conservation laws.
