The flaw of Solar Panels Designs is that the plane of reception will greatly weaken the ability to capture light, if the lack of solar tracking system, it will be greatly reduced. This conical solar collector uses conventional low-cost Solar Panels Designs to capture light from all angles, 20 times more power than static flat panel Solar Panels Designs. In addition, this module eliminates the need for expensive cooling systems and specialized materials, and the cone can generate a breeze by rotating to allow passive cooling.
Solar Panels Designs can generate electricity, thereby reducing the use of fossil fuels that emit greenhouse gases, and to combat global warming. At the same time, they can shield the earth from the sun. This extra cover should also be able to fight climate change because less solar radiation means more cool earth, right?
However, scientists have recently reported in Nature-Climate Change magazine that things are not that simple. Studies have confirmed that Solar Panels Designs actually make some places more hot. The researchers simulated an idealized scenario: a desert and a city area that was completely covered by Solar Panels Designs. Since the weather depends on many factors, the research team had to simulate an extreme situation to confirm that the observed changes were really caused by Solar Panels Designs.
The simulation shows that the extra shelter first makes the covered area cool, but the temperature drop has changed the local weather pattern. For example, about 50 years after the installation of the panels, India and eastern Australia have become more warm due to reduced precipitation. At the same time, the northwest of the United States because the wind mode changes have become more warm.
Nevertheless, the benefits of Solar Panels Designs still outweigh the shortcomings. In reality, large-scale Solar Panels Designs cover, can make local warming less than 0.5 degrees Celsius. This is far below the predicted global temperature in the next century will rise several degrees Celsius, provided that humans continue to burn fossil fuels. However, the authors suggest that large-scale installation of Solar Panels Designs should not be the only alternative to fossil fuels.
A solar cell is a device that responds to light and converts light energy into electricity. There are many kinds of materials to produce photovoltaic effect, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now crystal silicon as an example to describe the optical power generation process. P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
When the light is irradiated on the surface of the solar cell, a part of the photons are absorbed by the silicon material; the energy of the photon is transferred to the silicon atoms so that the electrons are transitioned and the free electrons are formed on both sides of the PN junction to form a potential difference. When the external circuit is turned on , In the role of the voltage, there will be a current flowing through the external circuit to produce a certain output power. The essence of this process is the process of converting photon energy into electrical energy.
