So we are all know that solar energy is an alternative energy source, but it really hasn’t been able to produce large enough results that we can use on a big scale. Fortunately, Swedish researchers have produced new nanotechology that improves solar power.
Solink — an ink made from nanowires that, when rubbed onto existing solar panels, can boost efficiency by 25%. This will allow solar power the efficiency boost that will enable it to finally compete with other energy sources. Previously, solar energy panels could not harvest the necessary amount of energy that would be capable of independently powering anything on a large scale without there being an enormous amount of solar panels.
So back to this new ink. The nanotech ink is added to conventional solar cells towards the end of the production process, which acts additively with the contents of galium arsenide (GaAs) nanowires. Galium arsenide is one of the most efficient photovoltaic materials, meaning can transfer solar energy into electric energy easily, out there — but it’s much more expensive than the typically used silicon. In essence, Sol Voltaics, building on advances made by Lars Samuelson’s research group at Lund University in Sweden, has found a way of cheaply producing large quantities of galium arsenide nanowires, and then producing an ink that is easy to apply to existing solar cells.
Adding this to the list of growing alternative fuels is going to greatly decrease our dependence on fossil fuels, lowering greenhouse gas emissions and other harmful by products of some energy sources. Our world is definitely finding ways get by under more difficult circumstances, showing our human resilience and ingenuity.
