Sun-powered desalination for villages in India

Sun-powered desalination for villages in India | Solar Energy projects & Energy Efficiency | Scoop.it
Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water -- and much of that area is not served by an electric grid that could run conventional reverse-osmosis desalination plants. Sun-powered desalination could deliver clean water for off-grid villages.

Now an analysis by MIT researchers shows that a different desalination technology called electrodialysis, powered by solar panels, could provide enough clean, palatable drinking water to supply the needs of a typical village.

PV plants in Germany are more profitable than expected

PV plants in Germany are more profitable than expected | Solar Energy projects & Energy Efficiency | Scoop.it

PV systems in Germany are regularly generating higher yields than expected. An investigation by Fraunhofer ISE links these higher yields to an upward trend in solar radiation, pointing out that the current radiation level in Germany is considerably higher than the average values of the last 30 years. As these average values have generally been used in yield predictions up to now, actual PV system yields are exceeding their forecasts by approximately five percent, making them more cost-effective than anticipated. To take this effect into account, Freiburg researchers have adapted their quality assurance services for PV systems and are now basing their yield predictions on solar radiation data from the last ten years.

Scientists shed light on organic photovoltaic characteristics | Solar Energy projects & Energy Efficiency | Scoop.it

Photovoltaic devices, also known as solar cells, produce electrical power when exposed to light, and that technology has enabled a fast-growing industry. The most familiar designs use rigid layers of silicon crystal. But recently, intense interest has focused on organic photovoltaic (OP) devices which use inexpensive organic semiconductor materials sandwiched between two metal electrodes. OP devices can be made flexible and easily portable. Imagine a tent that, once set up, acts as a large solar system that can be used to recharge portable electronics and lights for the upcoming night of camping.

Controlling the Growth of Perovskite Crystals Could Lead to Cheap Solar Cells | MIT Technology Review

Controlling the Growth of Perovskite Crystals Could Lead to Cheap Solar Cells | MIT Technology Review | Solar Energy projects & Energy Efficiency | Scoop.it

A new way to control the growth of crystalline materials called perovskites could lead to commercial solar cells that hit a sweet spot of high performance and low cost. Although individual perovskite cells have achieved promising results in the lab, until now it hasn’t been clear how they might be made in uniform batches.

Certain perovskites can harvest the energy of sunlight very efficiently because they strongly absorb both visible and infrared light. And unlike silicon films, which are made at high temperatures, perovskite films can be made from solution at much lower temperatures.

The Untapped Power of Solar Data : Greentech Media

The Untapped Power of Solar Data : Greentech Media | Solar Energy projects & Energy Efficiency | Scoop.it

Why we need to leverage big data to grow solar. 

Last year, the global solar industry surpassed 100 gigawatts of cumulative installed capacity, and it is quickly approaching 100 gigawatts of annual deployment. While solar has rapidly scaled up in the past ten years, there are several hurdles to clear before solar can make its way into the mainstream. One of the industry’s biggest impediments is that its technology is still perceived as “new” and therefore risky by the more conservative financial community.

“One of the reasons why the private market isn’t doing much with clean energy now is that it doesn’t understand the technology and its potential,” said Douglass Sims

It’s always interesting to attend conferences in far away places because of the change in perspectives. At the World Energy Security Forum (whose organizers I advised) in Johannesburg, there was the usual discussion of different energy sources and their roles, but also senior politicians with much experience in governing.

A very perceptive remark was made by former Prime Minister Odinga of Kenya, who, discussing NGO opposition to some energy projects in Africa, remarked, “You can’t have grandchildren if your daughter remains a virgin.” Similarly, he added that Africans wanted to conserve their environment, but not as a virgin environment.

The Solar Technology Behind Apple's iPhone 6

The Solar Technology Behind Apple's iPhone 6 | Solar Energy projects & Energy Efficiency | Scoop.it

Apple is expected to unveil a new iPhone 6 this week with a thin sapphire screen that is incredibly scratch resistant.

And the company can thank the solar industry for that innovation.

The super-thin screen is made through a process called proton induced exfoliation or PIE invented by Twin Creeks Technologies. With PIE, high-energy protons are fired at a crystalline material like sapphire or silicon and lodge in the material at a depth of around 20 microns. When heated, the ions form bubbles which ultimately link together and cleave off a thin crystalline slab that can be used as a screen or as a substrate for LEDs or solar cells. Hyperion, Twin Creeks’ first system for harnessing PIE, was in development for several years and debuted in 2012.
