Sweden has become a leader in the renewable energy field with powering 54 percent of its energy needs by the use of renewable energy.
Sweden set off early in the quest to become 100 percent renewable energy run nation. Way before the world even felt the need for renewable energy sources, this is the reason why Sweden is way ahead of the world in this sector. Sweden has tried everything in order to create more sustainable energy from solar plants to waste to energy plants. Sweden has been importing garbage from different countries so as to create clean energy without spending finite resources or harming the environment. Sweden has advanced its speed following the climate emergency that we are facing today. Most of the energy sources of the world lie at fossil fuel burning, which is a major source of carbon emission in the atmosphere, and as a result for warming of the global climate. To stop the burning of fossil fuels, in a world where energy demands increase every day, tapping of solar energy and converting it to electricity is one alternative. Though solar energy as an alternate form has been in use for a long time, scientists are now trying their hands on even more low-cost production so that it could be used in households in large numbers. Developing organic solar cells is one such effort. Organic solar cells have a multitude of advantages, such as its low-cost nature, durability, flexibility and lightweight character in comparison to the conventional silicon-based solar cells.
Feng Gao of Linkoping University, Sweden has co-authored research in which it showed that a single-junction organic voltaic cell could maintain 87% of their starting efficiency and an amazing durability of 68 days after exposure to solar radiation. In the same study, the researchers said that they could also develop another group of organic photovoltaic cells that were subjected to 20 suns of ultraviolet illumination. The cells were exposed to that level of radiation for 848 hours and they observed no loss of efficiency for that duration. It is indeed a test of efficiency and durability.
