Photovoltaic solar power generation system with sealed evaporative cooling

A solar power generation system, comprising:

• a condenser operable to receive a coolant in a vapor phase and condense the coolant to a liquid phase;
• and
• a plurality of modules, comprising:
• at least one photovoltaic cell having a first side and a second side;
• a solar concentrator configured to focus solar radiation on the first side of the photovoltaic cell;
• an evaporative chamber coupled to the photovoltaic cell proximate the second side, the evaporative chamber configured to receive the coolant in the liquid phase to remove heat from the photovoltaic cell, and
• at least one coolant supply line configured to direct the coolant in the liquid state from the condenser to the evaporative cooling chamber, and at least one coolant return line configured to direct the coolant from the evaporative cooling chamber to the condenser wherein the condenser, the coolant supply line, the evaporative cooling chamber, and the coolant return line form a closed circulation system.
