Next-generation solar panels boost efficiency but may carry toxic risk

Solar photovoltaic (PV) technology has evolved steadily since it was first developed by Bell Labs in 1954. It is now scalable, easily integrated with other energy technologies including batteries, and the cost of modules (commonly known as panels) has decreased by 80 per cent since 2009. Decades of improvements in engineering and manufacturing processes have led to moderately efficient, low environmental impact, silicon-based crystalline solar modules that fill rooftops and fields around the world. This is all about to change with new technology based on manufacturing techniques that use more toxic chemicals, including nanomaterials. Next-generation solar modules offer a lot of potential but might be more toxic than we expect.  Read more....
