(JP9246585-A)      The module includes a solar battery cell (12) which is provided on the inner surface of a transparent cooling pipe (10). A motor (14) is coupled to a cooling pipe through a crank (16). The cooling pipe is filled with a cooling medium (18) through which light is received and focussed on the solar cell.    A position detection sensor (24) detects the focal point position of the solar light. The tracking of the solar light is performed by positioning the cell by actuation of the motor based on signal from the position detection sensor.    ADVANTAGE -   Facilitates direct cooling of cell and use of cooling medium as lens. Reduces cost by enabling use of water as cooling medium.    (US6018122-A)      In the transparent cooler tube (10) the solar radiation is converged by the coolant (18) and the solar cell (12) is displaced into a position, enabling the convergence of solar radiation, changing due to the sun motion.    Preferably the coolant acts as a solar radiation lens with a refractory index for its convergence. The converged solar radiation position is picked-up by a position detector sensor (24), and a motor (14) displaces the solar cell into converging position according to signal from the position detector signal. The cell is mounted on a crank (16) which is coupled to the motor.    ADVANTAGE -   High precision of alignment to the impinging solar radiation, simple design, and effective cooling.
