    99% Solar power is what i wanted. I did it. My home is powered 24 / 7 / 360 days a year from the sun. Solar during the day and of a night i run off the stored sunshine in my Battery bank.

    Please feel free to enjoy my Off-Grid / Grid Hybrid system and my LED lighting videos. as well as my many How to videos.

    Never Be Without Power again.

    My Three most used sayings are.
    1) A house roof looks unfinished until it has solar panels on it.
    2) A man is not looking after his family until he is producing his own power.
    3) Solar systems can be kind of pricey at first. Having power when no one else does, PRICELESS

    Remember if the power go’s Out Then only the people that Prepared will have Power and Lights. And because of the cost. They have just enough for there needs. NOT YOURS.

    Graphene is a material made up of single-atom thick sheets of carbon which makes graphene flexible, conductive, transparent and abundant. Currently, researchers are trying to fully incorporate graphene into thin-film solar cells due to graphene’s high conductance and transparency; however, graphene cannot hold an electrical charge as well as some other materials. As a result, scientists are coming up with new ways to process graphene sheets so that they are better suited for use in solar energy applications.

    One way to improve the use of graphene in solar cells is to dope the sheets of graphene with oxygen to create graphene oxide which is less conductive but better able to hold a charge. If this technology is successfully developed and executed, it could replace the brittle and rare Indium Tin Oxide (ITO) which is a useful, but very expensive conductor. Another idea that scientists are investigating is stacking multiple sheets of graphene together to increase conductance and charge capacity. This allows less light to penetrate the surface of the solar cells but also increases the charge capacity, allowing the graphene sheets to outperform ITO.

    Both of these ideas for graphene usage in solar cells demonstrate the materials science paradigm of processing a material to obtain optimal properties for the application. Our video will talk about the structure of graphene itself and how processing the graphene differently alters the structure of graphene which improves its properties and allows it to perform better in photovoltaic cells. These positive effects of graphene usage in solar cells would clearly benefit the environment by creating cheaper and more efficient solar cells.
