随着物联网（IoT）的扩展，对节能、自供电设备的需求增加，因此有必要更好地了解可用的能源资源。我们研究了各种环境中能量收集光伏（PV）的光功率资源可用性及其自供电物联网应用的潜力。我们分析光源，考虑光谱分布，强度和时间变化，并评估位置，季节变化和一天中的时间对光功率可用性的影响。此外，我们还讨论了人类和建筑设计因素，如占用率、房间外观、传感器放置和装饰，这些因素会影响光能的可用性，从而影响物联网电子产品的功率。我们提出了一个最佳情况和非理想的情况下，在光资源的能量收集，并使用市售的有机光伏电池，表明产生的能量产量和可用于物联网电子产品，可以是任何地方之间的0.7 mWh和75 mWh每天，这取决于照明条件。
As the Internet of Things (IoT) expands, the need for energy-efficient, self-powered devices increases and so a better understanding of the available energy resource is necessary. We examine the light power resource availability for energy harvesting photovoltaics (PV) in various environments and its potential for self-powered IoT applications. We analyse light sources, considering spectral distribution, intensity, and temporal variations, and evaluate the impact of location, seasonal variation, and time of day on light power availability. Additionally, we discuss human and building design factors, such as occupancy, room aspect, sensor placement, and décor, which influence light energy availability and therefore power for IoT electronics. We propose a best-case and non-ideal scenario in terms of light resource for energy-harvesting, and using a commercially available organic PV cell, show that the energy yield generated and available to the IoT electronics, can be anywhere between 0.7 mWh and 75 mWh per day, depending on the lighting conditions.
