Nanotecnology & Phovoltaics

According to the EIA, by the end of 2035, the world will need 35 trillion kW/h which is nearly 100% increase from the year 2007. As the world population continues to increase, demand for electricity keeps rising. Rather than relying on coal, power plants, oil to power machines, the world needs a better answer to this problem of energy crisis. Photovolaic panels were first introduced in mid 1970‘s. The price of these panels have significantly gone down, however, it is still too costly and requires too much resources and is not very efficient. The world needs something smaller but just as effective. This can only be done in molecular level which requires little labor, time and resources. The National Renewable Energy Laboratory certified that Nanosolar’s panels are capable of capturing 15.3% of the sun’s light. And it’s all done on a thin piece of aluminum covered with what the company calls a nanoparticle ink. A video of the process shows that it is much like printing on paper. Nanosolar’s machines are capable of printing 100 feet of solar cells a minute. One of the companies at the forefront of the fight to make thin-fi lm solar viable is Nanosolar. The result of the front-end cell production is a roll of inexpensive aluminum foil substrate coated with multiple thin fi lm layers totaling less than two microns. Nanosolar‘s printed CIGS solar cells and panels are on track to reach efficiencies competitive with crystalline silicon panels in the next several years. Moreover, the Nanosolar Utility Panel’s innovative design significantly reduces balance-of-system costs through less mounting hardware, electrical cabling and installation labor. Nanosolar has achieved 17.1% efficiency on laboratory devices, certified by NREL, which shows the potential of our technology to compete with the efficiency of crystalline silicon panels in the next several years. Architecture in the near future will be expected to be able to generate power from the sun because sun is most likely to be the only energy source. Architecture in that future will be building integrated photovoltaics.
