Solar power to become cheaper in the future

Efficiency of solar panels got a boost - thanks to the research team from the University of New South Wales, Australia. The discovery involves a new way of splitting sunlight into four different cells, boosting its conversion levels.

In the traditional methods, usage of one solar cell is permitted which limits the conversion of sunlight to electricity to about 33 per cent. This newer technology splits the sunlight into four different cells, resulting in giving a boost to conversion levels.

According to the team leaders, this technique could be harnessed to push solar efficiency even further - potentially making solar technology amongst the most efficient and cheapest options in the energy mix.

The researchers described this innovation as world's first and were able to convert more than 40 percent of sunlight hitting the panels into electricity. Based on news report, "This is the highest efficiency ever reported for sunlight conversion into electricity".

According to the team leader, "We used commercial solar cells, but in a new way, so these efficiency improvements are readily accessible to the solar industry." The record efficiency level was achieved in tests in Sydney and replicated at the United States Government's National Renewable Energy Laboratory.

For bringing in improvement in the efficiency of conversion rate of sunlight in many of the solar panels installed in different rooftop buildings, the spokesperson adds, "The panels that you have on the roof of your home, at the moment they just have a single cell but eventually they will have several different cells... and they will be able to improve their efficiency to this kind of level".

With the above discovery, it becomes clear that conversion of sunlight in different solar panels is much better by adding more solar cells instead of relying on one solar cell for conversion.

Hoping the concerned quarters in India do take a note on the above for bettering the efficiency and productivity levels of solar panels in the country in the future with cheaper and better propositions, like the above.
