Their work combines into a single unit the photoelectric cells that gather sunlight and the electrolyzer that produces hydrogen.

他们发明出吸收太阳光的光电池以及生成氢气的分解剂。

But there is growing interest in the idea of using photoelectric cells to run gadgets as well as power grids-and doing so even when those gadgets are inside buildings.

可科学家们对于利用光电池来驱动用电装置和电网越来越感兴趣了—这些光电池即使在室内也能够正常工作。
