A solar cell module comprises an array of lenses, corresponding secondary optical elements and corresponding solar cell receivers. The solar cell receiver includes a solar cell having one or more III-V compound semiconductor layers, a diode coupled in parallel with the solar cell and connector for coupling to other solar cell receivers. The module includes a housing that supports the lenses such that each lens concentrates solar energy onto its respective solar cell.

A shutter assembly for a reactor includes a cylindrical shutter for selectively closing a passthrough opening of the reactor, the shutter forming a closed loop and including an internal cavity adapted to receive a cooling fluid, tubing connected with the cylindrical shutter for supplying the cooling fluid to the internal cavity, and an actuator connected with the tubing for moving the tubing and the cylindrical shutter. The cylindrical shutter is movable between a first substantially closed position and a second substantially open position.

A reactor for growing epitaxial layers includes reaction chamber having a passthrough opening for inserting and removing wafer carriers from the reaction chamber. A reactor also includes a cylindrical shutter located inside the reaction chamber for selectively closing the passthrough opening. The cylindrical shutter is movable between a first position for closing the passthrough opening and a second position for opening the passthrough opening. The cylindrical shutter includes an internal cavity adapted to receive a cooling fluid and tubing for introducing the cooling fluid into the internal cavity. The tubing is permanently secured to the shutter and moves simultaneously therewith. The cylindrical shutter and the internal cavity of the shutter surrounds an outer perimeter of the wafer carrier, thereby minimizing nonuniformity in the temperature and flow field characteristics of the reactant gases.
