摘要：
AC or DC? Protein-based photoelectrochemical cells that were constructed using a photosynthetic reaction center (left) generated a conventional direct current (DC) output during continuous illumination but an alternating current (AC) during regular light-on/light-off cycles (right). The mechanism of AC generation exploits the ability of nature's reaction centers to store charge as well as to catalyze highly efficient photochemical charge separation.
