  • 2. SApplications for this technology arevery diverse. It is conceivable thatnantenna collectors,combined withappropriate rectifying elements,could be integrated into the µskin¶of consumer electronic devices tocontinuously charge their batteries.Economical large-scalefabricationwould supportapplications, such as, coating theroofs of buildings andsupplementing the power grid. Dueto the ability of integrating thenanostructures into poly materials itis possible thatthey could even bedirectly fabricated into polyester

Available fluxthatreaches the earth¶s surface inthe .8-.9 um range is about800w/m2 at its zenith. Whilevisiblelight flux is dependent oncloud cover and humidity, incident

  • 6. building insulation, windowcoatings,and heat dissipation insmall electronic consumer products,such as, computers. Thenantennasare broadband collectorsof energy with a tailorable spectralemission response. This ineffectgenerates a frequencyselective distribution of energy.This potentially will collectunwantedenergy (residual orincident heat) and redistribute it atother innocuous wavelengths.CONCLUSIO
  • 7. NSAND FUTURE WORKFinally, the nanoantenna hasadvantages, disadvantages anduseful applications. Infact,currently, the largest problem isnot with the antenna device, butwith the electronic switchesandamplifiers, so that, a bringingphotonic switches and amplifiers tothe reality is the concerned of therecent researches. Because of theelectronic switches and amplifiersare unable to efficientlydeal withfrequencies which correspond tohigh-infrared to visible light.
  • 8. Therefore, a photonicsystem mustbe designed that can properly dealwith the absorbed light withoutconverted to theelectric energy.What is being seen in the far sightof the horizon is aphotonic processor. Bothmodelingand experimental measurementsdemonstrate that the individualnantennas can absorbclose to 90percent of the available in-bandenergy. Optimization techniques,such as, increasingthe radial fieldsize could potentially increase thisefficiency to even higherpercentages. Moreextensiveresearch needs to be performed on

Thenantennas can be formed on thin,flexible materials likepolyethylene.Further laboratoryevaluations of the flexible substrateNEC prototypes areplanned.Manufacturing methodswill continue to be refined tosupport roll-to-roll manufacturingof thenanostructures. Future workwill focus on designing thenantenna structure for operation inother wavelengths. By further

This research isatan intermediate stage and may takeyears to bring to fruition and intothe market. Theadvances made byour research team have shown thatsome of the early barriers ofthisalternative PV concept havebeen crossed and this concept hasthe potential to be a disruptiveandenabling technology.
