Abstract [en]

Energy harvesting (EH) was born few decades ago and evolved during the years, however only recently has found more applications thanks to the advent of wireless sensor networks and the developments in microchips technology.

This thesis investigates energy harvesting potentialities, in particular those related to solar harvesting in indoor applications. Some of the most common challenges are discussed such as: the best maximum power point tracking (MPPT) algorithm for indoor systems; or the effect of partial shading on output performances.

Mathematical and analytical models, for solar panels and batteries, are proposed to simulate at first and simple energy harvesting system.

Furthermore two solar technologies, the present one (silicon cells) and the future one (dye sensitized cells), are simulated and tested to exploit their potentialities.

Finally different commercial solutions are examined and compared to pick the most relevant for this thesis. They are connected to the solar cells and the output characteristics are measured to determine their performances at different illuminances.
