摘要 |
This invention is a thermoelectric-photovoltaic device for converting electrical energy from both thermal radiation and sunlight. Thermoelectric energy is produced from thermoelectric cells when a temperature difference is present between two different semiconductor materials. Photovoltaic energy is produced from photovoltaic cells when two different semiconductor materials are exposed to sunlight. To achieve increased electrical energy production, one of the semiconductor materials is placed in a cell having a reduced pressure atmosphere to increase the radiative energy thermal exchange with the black sky at night. |
