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. Much of the light these cells used would, of necessity, come from incandescent bulbs, fluorescent tubes and light-emitting diodes (LEDs) rather than through the window from the sun. But if the right sorts of cells were available this could be cheaper than constantly replacing the batteries that currently power electronic gizmos. 　　室内太阳能这个词听起来有点儿自相矛盾,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。它们所利用的光能中的大部分势必来自白炽灯，日光灯和发光二极管，而并非透过窗户照射进来的太阳光。不过一旦某种特殊的光电池被研发出来，相比于通过频繁更换电池为用电装置供电的传统方式，新型光电池的应用将能够大大降低成本。 　　On April 8th G24 Innovations, a firm based in Wales, announced that it may have come up with just such a cell. The latest version of its special, dye-based photoelectric devices has set a new record for the conversion of light from bulbs into electricity: an efficiency of 26%, compared with the 15% which previous ones can manage. That lifts dye-based cells to the point where they might be widely deployable for indoor power. 　　在四月八日，一个总部位于威尔士的公司——G24 Innovations宣布他们已经开发出这种光电池。它的独特之处在于其基于染料的光电转化设置，该装置必威体育精装版版本的转化效率已经从上一代的15%提高到创纪录的26%。这大大增加了将该类型电池应用于室内供电领域的可能性。 　　Dye-based cells are similar to the silicon-based variety found on rooftops around the world in that both rely on a semiconductor to assist the conversion of luminous energy into the electrical sort. The difference is that in the case of silicon cells, this conversion happens directly. That means the frequency of light absorbed is constrained by the physical properties of silicon itself. 　　这种基于染料的光电池同另外一种基于硅的光电池——如今已在全世界广泛应用，与屋顶随处可见——比较相似，它们的光
