Solar power system and high efficiency photovoltaic cells used therein |
摘要 |
A solar power system including a movable platform for tracking the sun, a radiation concentrator, and a plurality of photovoltaic cell modules positioned on the platform for receiving concentrated solar radiation. The module includes a heat dissipation housing which supports a silicon cell across an open end of the housing. A heat transfer block physically engages the silicon cell and a metallic sponge and wick is attached to the heat transfer block and depends therefrom into the housing. The housing is partially filled with liquid to facilitate heat removal. The silicon cells are processed by preferential etching to form V grooves which define a plurality of diode elements having generally trapezoidal cross-sections. The elements may be serially interconnected by metallization on the V groove surfaces. The physical configurations of the elements and the use of antireflective coatings on surfaces of the elements result in high efficiency cells.
