How Nanotechnology is boosting Solar energy

hi welcome to this video in which we will explore how nanotechnology is positively impacting solar cell development on this channel synergy files we aim to inspire budding engineers and technicians for a better more sustainable world subscribe to the channel today to get the updates of our latest videos before we begin to explore how nanotechnology is boosting solar industry we must learn what is nanotechnology definitions of nanotechnology are wide-ranging but perhaps the easiest to comprehend is that nanotechnology refers to the manipulation of matter with at least one dimension size from one to a hundred nanometers we have observed that as we purify and strip down materials into smallest of scales then these materials depict remarkable properties that cannot be observed in their scaled up and crude versions we have noticed super strength very high electric and thermal conductivity and even transparency in the tiniest pieces of the same material that are otherwise absent in their macro scale counterparts graphene is a classic example at a macroscopic level it can be a chunk of carbon like graphite as in the pencil let peel it down to a single layer and it becomes a wonder material nanotechnology has made its mark on the aviation industry it has helped us in making aircraft that can travel further and now it's helping us getting the most out of solar energy a good example of this is dye sensitized solar cells or DSS see through nanotechnology we have been able to make solar cells that marek the way plants harness energy that is photosynthesis there are quite a few advantages of DSSC they can be made semi-transparent they can be made flexible and can also harness more sun rays when there's a greater cloud cover another example of the use of nanotechnology in solar application is the research going on in Kyoto University they've developed a silicon based nano semiconductor which can harness more wavelengths from the spectrum of solar light energy the way it achieves this is through atching silicon layers to have a large number of identical and equally spaced rods the height and radii of spacing of which was optimized for the target bandwidth this allows more of the light to be reabsorbed by silicon to excite the electrons then to be converted as heat you this material the team has shown that their nanoscale semiconductor raises the energy conversion rate of solar cells to at least 40 percent similarly using nanotechnology coatings have been developed for solar thermal applications that do the opposite that is they captured the sun rays and effectively convert them into heat lastly we have also explained in a previous video the research that is being carried out on the use of graphene and solar panels in three different ways the most likely technology that will materialize in the near future is the use of graphene as a charge carrier in solar panels so that concludes the video we have some links in the description section for you to explore more about the technological developments in this area if you like the video do give it a thumbs up thank you for your attention
