Abstract
A restoration device of at least one silicon-based photovoltaic solar cell is provided with a support of the cell and a charge carriers generator configured to generate charge carriers in the photovoltaic solar cell. The device is further provided with a tank designed to be filled by a liquid, and the support is configured to place the photovoltaic solar cell in the liquid.
Claims56
A restoration device of at least one silicon-based photovoltaic solar cell, said device comprising:
- a support of the photovoltaic solar cell;
- a charge carriers generator configured so as to generate charge carriers in the photovoltaic solar cell;
- a tank designed to be filled by a liquid, wherein the liquid is a heat transfer liquid or a soluble cutting oil;
- and
- a regulator of a liquid temperature, wherein the regulator is configured to regulate the temperature of the photovoltaic solar cell to a target temperature value or range comprised within the 50° C.-230° C. temperature range,
- wherein the support is configured to arrange the photovoltaic solar cell in the liquid.
A restoration method of at least one silicon-based photovoltaic solar cell to counteract degradation of the efficiency under illumination, comprising:
- generating charge carriers in said cell, and
- immersing the photovoltaic solar cell in a liquid when generation of charge carriers takes place, so as to regulate the temperature of the photovoltaic solar cell to a target temperature value or range comprised within the 50° C.-230° C. temperature range.
A restoration device of at least one silicon-based photovoltaic solar cell, said device comprising:
- a support of the photovoltaic solar cell;
- a charge carriers generator configured so as to generate charge carriers in the photovoltaic solar cell;
- a tank designed to be filled by a liquid;
- and
- a support movement system configured to move the photovoltaic solar cell in a direction parallel to the surface of the liquid in the tank
- wherein the support is configured to arrange the photovoltaic solar cell in the liquid.
A restoration device of at least one silicon-based photovoltaic solar cell, said device comprising:
- a support of the photovoltaic solar cell;
- a charge carriers generator configured so as to generate charge carriers in the photovoltaic solar cell;
- and
- a tank designed to be filled by a liquid,
- wherein the support is configured to arrange the photovoltaic solar cell in the liquid, and the support comprising pass-through holes so that the liquid is in contact with a surface of the photovoltaic solar cell arranged on the support.
A restoration device of at least one silicon-based photovoltaic solar cell, said device comprising:
- a support of the photovoltaic solar cell;
- a charge carriers generator configured so as to generate charge carriers in the photovoltaic solar cell;
- and
- a tank designed to be filled by a liquid,
- wherein the support is configured to arrange the photovoltaic solar cell in the liquid, and the support is made from a material having a higher thermal conductivity than the thermal conductivity of the photovoltaic solar cell.
