Note: Since nano-antennas have the ability to absorb a wide angle, even  if the sun is inclined to the surface of the solar panel, their efficiency is maintained to a considerable extent. The system can also absorb energy  emitted from the ground, or ground radiation from the  sun's daily radiation to the earth's surface, at wavelengths of 10 micrometers , or frequencies of about 90 terahertz.

 For this  reason, nano-antennas of the solar rectana system can generate electrical energy by collecting this radiation during the night or in bad weather conditions  At present, the diode and antenna structures used in the solar rectum  are made using the electronic design method. Although this method of  construction is expensive and time consuming to produce on a laboratory and research  scale, but if these structures are produced in large volumes and with the appropriate method  , they will reduce the cost and speed of the manufacturing process.






It should be noted that Rectenna Rectenna has been studied in recent years, especially in the field of power transmission in the  microwave band. For example, in theory,  for a single frequency of 9.2 GHz, more than 10% efficiency is predicted  Of course, the practical efficiency of making these devices may  be slightly different and must be determined in practice. The dipole antenna with linear polarization  and length 2 / λ, which has a relative bandwidth of 11%, will be able to  collect about 75.2 pW  With  regard to the low received power independent of each antenna, using an array of antibiotics  in these cells is customary laws and its own procedures  there.Because the use of optical nano-antennas to collect solar energy offers a practical solution that is more efficient than other common photovoltaic technologies such as solar panels, it has led to the rapid development of nanotechnology and optical materials.



Conclusion : 

Because nano-antennas have the ability to absorb a wide angle, their efficiency is maintained to a considerable extent even  if the sun is inclined to the surface of the solar panel The system can also absorb energy  radiated from the earth, or ground radiation from the  sun's daily radiation to the earth's surface, at wavelengths of 10 micrometers , or frequencies of about 90 terahertz.
