“…However, if a SOI technology [11] had been used, there would be no problem in sharing the substrate, because the latter would be an insulator and thus would provide the necessary electric isolation between the independent structures placed on it, although at a higher cost.…”

“…This also makes impossible to connect two CMOS PV cells in series, since all the diffusions in CMOS are less than 1 μm in depth. The only option to connect PV cells in series is to use non-standard CMOS technologies such as SOI CMOS [11], because in this case, each PV cell is electrically isolated from its neighbors. However, this technology is much more expensive than standard CMOS technology.…”

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.

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.

In this paper we present a 4-mm 2 battery-less temperature sensor, designed to collect and periodically transmit information to an ambient monitoring system. It consists of a 0.35-µm BCD SOI technology based chip including an ultra-low power integrated circuit and an energy harvesting supply unit made by 34 series-parallel connected photovoltaic cells. Each cell consists of a trench insulated p-n junction. Series connections among cells are possible because of the lack, guaranteed by the SOI insulation, of the substrate parasitic diode, typical in standard CMOS technology. The system is fully compliant with real-time applications and can work in low illumination conditions and with large variations of the photovoltaic voltage.
