专用集成电路,光伏电池使室内照明能量收集
室内照明为许多应用提供了一个方便的能源,但缺乏高功率的太阳能。事实上,室内照明能量收集系统面临着一些不同的微妙之处,从太阳能采集所遇到的挑战。然而,工程师可以快速实现能量回收设计使用的各种组件和生产商包括Cymbet,IXYS,线性技术,松下,意法半导体专用设备和仪器,德克萨斯,等等。
当太阳能能达到足够的功率,使整个建筑物和小城镇,室内照明呈现明显不同的特点。由于人眼的显着的能力,以适应非常广泛的照明水平,人们往往会认为相对较少的照明在多云的天空和明亮的房间,例如。然而,收获的能量水平之间的不同。事实上,即使是最好的室内照明的功率密度基本上低于太阳能,可以相差几个数量级(图1)。

PV differences
These differences translate directly into energy-harvesting output. A solar cell optimized for sunlight can generate about 40 mW per square inch in full direct sunlight. In contrast, even a large high-efficiency crystalline cell will generate less than a milliwatt from typical office lighting sources.
At the same time, the spectral sensitivity of photovoltaic (PV) cells used for outdoor and indoor energy harvesting differs in line with the nature of their respective sources. Typical solar cells used in outdoor applications have a spectral sensitivity range of 500 nm to 1100 nm.
