“Researchers develop cheaper way of making solar cells”

A team at Liverpool University has found a way of replacing the toxic element in the process with a material found in bath salts.

The scientists say that this could have a “massive, unexpected cost benefit”.

More than 90% of the solar cells are made from silicon. Around 7% are made from a material called cadmium telluride. The cadmium telluride cells are thinner than silicon and these are popular because they are also lighter and cheaper.

They have the drawback that a toxic chemical, cadmium chloride, is needed to manufacture them. Cadmium chloride is also expensive.

Dr Major discovered that a cheaper, non-toxic alternative, magnesium chloride, could be used instead of the toxic compound and work just as well.

Magnesium chloride is completely safe. It is used to make tofu and is found in bath salts. It also extracted from sea water and so is a small fraction of the price of cadmium chloride.

“Chinese Solar Growth to Underpin Record Global Expansion in 2014”

Solar developers around the world will install record capacity this year as a thriving Chinese market drives growth, a Bloomberg survey showed as manufacturers in the $102 billion industry began to return to profit.

About 44.5 gigawatts will be added globally, a 20.9 percent increase on last year’s new installations, according to the average estimate of nine analysts and companies. That’s equal to the output of about 10 atomic reactors. Last year new capacity rose by 20.3 percent, after a 4.4 percent gain in 2012.

2013 looks like it was the year that the Sun started shining on the solar industry.

A new multi-university study focusing on the fundamental science of charge separation has resulted in a greatly improved understanding of the subject — an improved understanding that should lead to more-efficient organic solar cells in the near future, according to those involved.

“Low-Cost Solar Cells Moving Closer Thanks To New Research On Electrodes”

Low-cost solar cells appear to now be one step closer to becoming a commercial reality, based on the findings of new research from the Okinawa Institute of Science and Technology (OIST).

The researchers at OIST have been working on the creation of solar cells based on organic materials that possess electrodes that are both flexible and transparent — potentially allowing for the fabrication of low-cost solar cells.

“How Wall Street suddenly fell in love with solar”

Over the weekend, the New York Times noted that the solar power “craze” is partly responsible for Wall Street’s recent good times. The Times used the example of solar giant SolarCity, which has seen a sevenfold increase in its share price to $59.27 since it went public, but this could just be starters for the US solar industry. An international research team based at North Carolina State University has come up with a simple way to increase the efficiency of organic solar cells by more than 30 percent, leading to lower costs and a much bigger market.

Deutsche Bank predicts second solar “gold-rush”

Leading investment house Deutsche Bank has dramatically lifted its demand forecasts for the global solar industry – predicting that 46 gigawatts (GW) of solar PV will be installed across the world in 2014, before jumping by another 25 per cent to 56GW in 2015.

As we have seen in other financial bubbles, speculation leads to the creation of overcapacity and then the bursting of the bubble.
