- 8. N P The photoelectric effect or photo ionization is the emission of electrons or other free carriers when light is shone onto a material. Electrons emitted in this manner can be called photo electrons. SOL AR CEL L e e e e Solar energy electrical energy
- 16. TABOO…… GALAXY SUN ALIENS PLANETS ___ ___ ___ ___ ___S P A C E

- 19. DESIGN In space there is no cloudy day hence we can get very good quantity of solar energy. We will only need 1- SOLAR PANELS 2-RECEIVERS
- 20. HOW IT WILL WORK? 1-solar panels will receive sunlight from sun. 2-SBPS will convert the sunlight to microwaves so there will be no energy loss. 3-microwaves will be transmitted and will be received by receivers on earth.
- 21. LAUNCHING
- 22. LAUNCHING It is the most difficult part which can create problems in our aim of getting solar energy from space. Taking lots of solar panel from earth will require huge amount of time and money so instead of sending thousands of solar panels into orbit ,we could just send up one that is programmed to make copies of itself ? and then each machine it makes would make copies of itself and so on......like multiplying rabbits the population of solar panel satellites will grow exponentially. It is difficult but not impossible ,many international agencies are working on it.
- 23. COST The cost of sending thousands of solar panels to space will be much more .even one space launch costs about 60 million dollars, it will cost trillions of dollars to send these panels so our scientists are working on making a machine which can produce copies of itself which can reduce the cost.
- 24. ADVANTAGES 1- unlike other power plants it will not produce poisonous waste 2-It will collect solar energy 24 hours a day and 7 days a week 3-the electricity can be provided in any part of earth just by setting a receiver. DISADVANTAGES The main disadvantage is the cost of setting solar panels in space.
- 25. TABOO…… Basicunit Organelles Nucleus biology ___ ___ ___ ___ C E L L
- 26. The California-based “BioSolar” company has developed a novel technology to produce bio-based materials from renewable plant sources, which could significantly reduce the cost of solar cells. By replacing petroleum-based plastic solar cell components with bio-based materials, the company says it can achieve cost reduction of up to 50% on thematerialsbeingreplaced.
- 27. A team led by MIT researcher andreas mershin, continuing an8-yearresearchproject of shuguang zhang, has developed a viable means by which agricultural waste– like grass clippings and leaves– can be used to create solar panels within a few years, the technology could be used so that people in remote and developing regions can generate their own electricity withfewmaterialsandatlowcost.

- 28. Environmentally compatible production methods for organic solar cells from novel materials are in the focus of "MatHero". The new project coordinated by Karlsruhe Instituteof Technology(KIT) aims at making organic photovoltaics competitive to their inorganic counterparts by enhancing the efficiencyoforganicsolarcells,reducingtheir production costs and increasing their life- time. "Green" processes for materials synthesis and coating play a key role. "MatHero" is funded by the European Commission with an amount of EUR 3.5 million.
- 29. TABOO…… Texture Fibre Body Yarn ___ ___ ___ ___ ___ __F A B R I C
- 31. Coated in a conductive polymer material, this half-inch square of fabric contains an array of six rectangular solar cells.
- 32. A Chemist and a Designer Team Up to Weave Solar Panels Into Fabric. Fabrics, as opposed to smooth and shiny glass or plastic, are porous, which makes evenly coating them with specific polymers a bit tricky. If you consider how a piece of fabric is created, it’s made up of multiple fibers twisted together. Each fiber will have a different level of roughness, which, from a chemistry standpoint, includes multiple light scales (nanometer, micrometer, etc.
- 33. When light shines on a solar textile, the solar cells on the textile fabric convert some of the light into electricity.
- 34. This is how it works!!!
- 35. THEYAREORIGINALLYDESIGNEDASEASILYDEPLOYABLECANOPIESFORMILITARY APPLICATIONS.. The solar fabric could even act as a shading for your sunny deck… The fabric is easy to install without any heavy duty mounting hardware….!
- 36. In comparison with regular solar panels, solar textiles are: lightweight portable robust versatile provide flexibility
- 38. While prosthetics are usually fully powered using batteries, a new prototype from University of Glasgow researchers opens up the possibility for solar-powered skin, which would include better sense capabilities than current technology. Amputees with prosthetic limbs may soon get a better sense of touch, temperature and texture, thanks to the energy-saving power of the sun.

- 49. The sun is a clean and inexhaustible source of energy. With the potential to provide a sustainable answer to all future energy supply demands. There is major problem i.e. the sun doesn't always shine and its energy is hard to store.
- 50. Allows solar energy to be stored in the form of chemical bonds. It is the separation of water into hydrogen and oxygen like plants do. The hydrogen obtained can then be used either directly as a fuel,
- 51. oWorks by sandwiching a photovoltaic cell oThe hydrogen it produces is a versatile fuel oEfficient than a field-grown plant, oIt has not been widely adopted because it gives gaseous fuel .
- 53. TABOO…… AQUATICLIFE HYDROGEN OXYGEN FLUID ___ ___ ___ ___ ___W A T E R
- 54. This technological innovation means the platform could be setup on water bodies like sea, rivers, etc for meeting captive energy requirements as well as for the conservation of lakes and ponds..
- 55. It saves agricultural land. Reservoirs are a great place to float solar panels, because shading the water helps to prevent evaporation, saving water and increasing efficiency One additional benefit is that solar panels are less efficient at high temperatures, and the water keeps them cool. In theory, one should be able to get more out of a floating solar farm than the same panels installed on land.
- 56. Chandigarh gets the first Floating Solar Power Plant in India In February, the world largest floating solar farm will be plugged in near Heathrow. Its 23,000 panels float on the Queen Elizabeth II reservoir at Walton- on-Thames, and it will provide power for one of London’s main water purification plants
- 57. GUESS THE RIDDLE !! Though I’m not an elephant… I am something with a trunk… If I get old and rusty.. You might sell me off as junk…
- 58. A solar car is a solar vehicle used for land transport. Solar cars only run on solar power from the sun. To keep the car running smoothly, the driver must monitor multiple gauges to spot possible problems. Cars without gauges almost always feature wireless telemetry, which almlows the driver's team to monitor the car's energy consumption, solar energy capture and other parameters and thereby freeing the driver to concentrate on driving. Solar cars combine technology typically used in the aerospace,bicycle, alternative energy and automotive industries.
