We address the problem of modeling the thermal behavior of photovoltaic (PV) cells that, due to their being exposed to shading, may experience a dramatic temperature increase (a phenomenon referred to as hot-spot) with consequent reduction of the provided power. Our proposed model has been validated against experimental data, and constitutes a first preliminary step towards the development of shading-tolerant approaches, while also highlighting a counterintuitive PV cell behavior useful to energy efficient PC array design.

Abstract
We address the problem of modeling the thermal behavior of photovoltaic (PV) cells that, due to their being exposed to shading, may experience a dramatic temperature increase (a phenomenon referred to as hot-spot) with consequent reduction of the provided power. Our proposed model has been validated against experimental data, and constitutes a first preliminary step towards the development of shading-tolerant approaches, while also highlighting a counterintuitive PV cell behavior useful to energy efficient PC array design.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
