收集环境可再生能源资源，如室内光，是一个可行的解决方案，自主的，“安装和忘记”，环境纳米传感器的发展。在这项工作中，我们制造和表征了基于AgBiI 4 rudorffites的光伏电池，作为有前途的室内光伏能量收集器，在1000 lux的白色LED光下测得的光转换效率为5.17%，功率输出为1.76 μW cm−2。考虑到现代低功耗无线发射机的数据传输每比特消耗<1 μJ，室内鲁道夫光伏电池结合超级电容器可用于传感器读出和可靠的间歇数据传输。
Harvesting of ambient renewable energy resources, such as indoor light, is a viable solution for the development of autonomous, “install-and-forget”, environmental nanosensors. In this work we fabricated and characterized photovoltaic cells based on AgBiI4 rudorffites as promising indoor photovoltaic energy harvesters demonstrating photoconversion efficiency of 5.17% and power output of 1.76 μW cm−2 measured under white LED light of 1000 lux. Considering that modern low-power wireless transmitters consume <1 μJ per bit for data transmission, the indoor rudorffite photovoltaic cell combined with a supercapacitor can be used for sensor readout and reliable intermittent data transmission.
