Singapores natural constraints coupled with her growing energy appetite heavily demands for efficient urban energy solutions. Tapping on Singapores strategic location within the Asian Sunbelt [1] allows Singapore to receive an average annual solar radiation of up to 1,150kWh[2], 50% more radiation then other countries like Germany and Japan who are leaders in this area of green technology. As a Living Laboratory, companies are encouraged to develop and test alternative energy solutio ns in Singapores urban context, where almost half of our US$269 billion renewable energy investment spending is targeted at the solar energy industry. [3] Scientists have showed that if we can utilize solar energy on the Earth, we can save electricity generation cost incredibly. Currently, there is major problem: The undesired excessiveness sunshine in our skyscrapers, which makes us uncomfortable due to its intense light and heat, rising considerably air-conditioning electric bill fee. If there is something that can absorb this wasted energy, it is the solution for both our concerns.
Solution: SolarWindow Material used : Polymer Solar Cells (PSCs) are semi-transparent solar cells are made of nano-silver films placed on a polymer. It produces energy by absorbing mainly infrared light, not visible light, making the cells up to 70% transparent. [4] Advantages: Lightweight, flexible and have low cost of production [5]
