Paul Kent, Jason Gao How Viable are Solar Panels Really? (Working Title) Abstract We analyzed that solar panels may or may not be a viable source of energy. There are many factors that contribute to the energy output, but one of the most important factor is the quality of the panels to generate electricity. Solar energy is quite unique from other dominating energy sources since the energy doesn’t deplete. But weather and other obstacles could prevent the collection temporarily. Two researchers mixed titanium dioxide with photoanodes by sinter-ing them. Then they added Ruthenium N749 dye to assemble into a completed solar panel. A team of researchers used carbon rather than silicon to build the solar cells. They spinned the pan-els while spraying carbon nanotubes across it. Another team of researchers applied organic dyes to panels where all layers could harvest photons. The experiments analyzed found that solar panels using the concepts analyzed converted no more than 5% of absorbed energy into electricity. The tested organic cell film had 1.5-2% ef-ficiency, though organic cells are inefficient but cheap anyway. Carbon cells were estimated to have no more than 5% efficiency. Experimental data found cells sensitized with dye and TiO2 achieve 4-4.5% efficiency if constructed correctly. Each US square meter gets about 1-2 thou-sand kilowatt-hours sunlight per year, which means the maximum power from a solar panel is about 110 kilowatt-hours per square meter per year. Since
