Abstract
The restoration device of least one silicon-based photovoltaic solar cell includes a support of the cell, a heat source configured to heat the photovoltaic solar cell, and unit for generating charge carriers in the cell. To better accelerate the restoration kinetics of the solar cell, the device includes an ultrasonic transducer designed to generate ultrasonic waves propagating in the photovoltaic solar cell.
