The dark also produce electric light source? Scientists invented reverse solar cells

Laptop battery chip, the researchers say, the concept verification equipment with low cost, and photovoltaic ready-made goods belong to which industry component manufacturing, total cost less than $30. Though the sky radiation cooling energy directly to get energy from the sun than solar cells is much less, but enough to light up an LED light bulb. The energy generated 2019 polysilicon market also can be used to small sensors in the wilds of power supply. Glass curtain wall to hang the device not only can be used at night can also reverse the work during the day, photovoltaic (pv) belong to which industry absorb sunlight, laptop battery chip and generate electricity from heat from the sun to disk. The device USES the temperature exchange, and convert it into electricity. At night, the ground than the air is warm, this means that the earth's radiation heat, a process called sky radiation cooling. Polysilicon which positions better to do it by a polystyrene box with aluminized mylar, there is a painted black and stick in the above 200 mm aluminum plate as & other; Thermal emitter & throughout; 。 This helps provide reliable energy off-grid areas throughout the world. Solar street lamps wholesale prices, according to foreign media reports, the glass curtain wall hang at Stanford university researchers developed a & other; Reverse throughout the solar cell &; The earth at night, can take advantage of the radiation heat producing electric light source.
