“…The PV cell causes a positive voltage in the substrate, thus causing a possible latch-up condition in the die. Also, when a series connection of several devices is required, the fact that the diodes are built on the same substrate may be limiting [70]. This limitation has become evident in a PV cell that was manufactured and that appears reported in Chap.…”

This chapter presents a literature review about the various ambient energy sources that can be harvested and the description of some related systems. As such, this chapter will provide a brief overview about each source and describe some systems that use that same energy source. This will be extended on to the domain of the wireless sensor networks and the aspects related to it, being presented some examples of energy harvesting powered WSN in different environments. A brief description of what is expected from each network and how it succeeds in harvesting the energy that enables it to work will receive a particular focus. Since light is the energy source being harvested, in order to power the system described in this book, some more attention will be dedicated to the analysis of this source.

The content which this chapter presents is intimately linked with photovoltaics. A set of general definitions regarding this subject is given. In addition, a general overview about the evolution and trends of PV technologies is also presented, in order to have an idea of how one could get to the present state of the art. To complete this chapter, an experimental development about an integrated PV cell, ranging from its electrical modeling to its layout, complemented with experimental results, is presented. To close this chapter, a study about the availability of light energy in an indoor environment is carried out, serving as the basis to size a PV array specifically designed and manufactured to operate in a scenario with such characteristics.

“…It is expected to work with weak power supply such as DSSC that is often accompanied with the wireless sensor network because it can be fabricated on flexible, transparent, or durable substrate [10]. Power management system for wireless sensor network delivers power to the sensor when sufficient power is accumulated to communicate with the host transponder [13], or keeps the surplus of power in the attached battery to keep periodic communication during the energy harvesting is impossible.…”

Abstract-This paper presents a power management system of the dye-sensitized solar cell (DSSC) for ubiquitous sensor network (USN) applications. The charge pump with a luminance-controlled oscillator regulates the load impedance of the DSSC to track the maximum power point (MPP) under various light intensities. The low drop-out regulator with a hysteresis comparator supplies intermittent power pulses that are wide enough for USN to communicate with a host transponder even under dim light conditions. With MPP tracking, approximately 50% more power is harvested over a wide range of light intensity. The power management system fabricated using 0.13 µm CMOS technology works with DSSC to provide power pulses of 36 µA. The duration of pulses is almost constant around 80 µs (6.5 nJ/pulse), while the pulse spacing is inversely proportional to the light intensity.
