PCT No. PCT / NZ95 / 00084 Sec. 371 Date Feb. 28, 1997 Sec. 102(e) Date Feb. 28, 1997 PCT Filed Sep. 14, 1995 PCT Pub. No. WO96 / 08683 PCT Pub. Date Mar. 21, 1996A solar concentrator for producing usable power as heat and / or electricity uses a self-steering heliostat 1502 to concentrate solar radiation 1509 onto an absorbing surface such as, or including, a solar cell array 1511 capable of absorbing power from the radiation, meanwhile removing heat (such as from long-wave infra-red radiation or resistive losses) from the surface with fluid heat transfer means 1503, 1504, then making effective use of that low-grade heat. Thus the solar cell array is kept relatively cool and a larger proportion of the solar energy incident on the reflector unit is used. The invention uses electricity 1506 from the solar cells to move a transporting fluid through a heat exchanger 1504. Excess electricity may be available for local storage or use 1510, or feeding 1512 to the power distribution grid. Applications include warming swimming pools 1501, heating hot-water supplies using excess electricity, or warming, lighting and ventilating open spaces.

A concentrating photovoltaic module is provided which provides a concentration in the range of about 500 to over 1,000 suns and a power range of a few kW to 50 kW. A plurality of such modules may be combined to form a power plant capable of generating over several hundred megawatts. The concentrating photovoltaic module is based on a Photovoltaic Cavity Converter (PVCC) as an enabling technology for very high solar-to-electricity conversions. The use of a cavity containing a plurality of single junction solar cells of different energy bandgaps and simultaneous spectral splitting of the solar spectrum employs a lateral geometry in the spherical cavity (where the cell strings made of the single junction cells operate next to each other without mutual interference). The purpose of the cavity with a small aperture for the pre-focused solar radiation is to confine (trap) the photons so that they can be recycled effectively and used by the proper cells. Passive or active cooling mechanisms may be employed to cool the solar cells.

InactiveUS20070289622A1Improve efficiencyEconomic return investmentSolar heating energySolar heat collector controllersWorking temperatureEngineering
A solar energy conversion package includes a photovoltaic (PV) cell, a thermionic or thermoelectric conversion unit and a thermal heating system. Solar radiation is concentrated by a lens or reflector and directed to the PV cell for electrical power conversion. A water circulation system maintains the PV cell at working temperatures. The thermionic or thermoelectric conversion cell is coupled between these cells in the thermal path to generate additional power. Additional efficiencies may be gained by partitioning the solar radiation with prisms or wavelength specific filters or reflective coatings into discrete spectrum segments optimized for each conversion unit for maximizing efficiency of electrical energy conversion and equipment design. Integrating all three of these conversion techniques produces a synergistic system that exceeds the performance conventional solar conversion systems.

InactiveUS20090173375A1Useful heatHigh strengthSolar heating energySolar heat devicesEffect lightForced-air
Methods and devices are presented that allow the harvest of electricity, heat and lighting simultaneously from a solar converter, often at less cost than conventional solar collectors. The converters use slats to intercept sunlight. Slat surfaces in the direct light path may be coated with photovoltaic (PV) material, or may be shaped to concentrate sunlight, allowing less PV material to capture reflected, concentrated light for improved economics. Forcing air flow past enclosed slats let the slats operate as PV heat sinks, heat absorbers, and heat exchangers capturing much of the solar energy that is not converted to electricity, as heat. Embodiments also allow passage of indirect light to supplement interior artificial lighting, often with positive aesthetic effects. These slatted apertures mitigate glare and overheating problems associated with typical skylights and some windows, allowing wider use as architectural elements. The devices also can be integrated into new building construction, and serve a dual purpose as building structural components.
