Mention prime geography for generation of solar energy, and people tend to think of hot deserts. But a new study concludes that some of the world's coldest landscapes -- including the Himalaya Mountains, the Andes, and even Antarctica -- could become Saudi Arabias of solar.

An online tool called "Impurities to Efficiency" (known as I2E) allows companies or researchers exploring alternative manufacturing strategies to plug in descriptions of their planned materials and processing steps. After about one minute of simulation, I2E gives an indication of exactly how efficient the resulting solar cell would be in converting sunlight to electricity.

Taking the pulse of charge-separation processes: Self-organization gives rise to more efficient organic solar cells
Organic solar cells have the potential to convert sunlight into electrical energy in an economical and environmentally friendly fashion. The challenge is that they still work less efficiently than inorganic semiconductors. Ultrafast measurements on hybrid cells now reveal a route to double their efficiency.

The concept of the hydrogen economy (HE), in which hydrogen would replace the carbon-based fossil fuels of the twentieth century was first mooted in the 1970s. Today, HE is seen as a potential solution to the dual global crises of climate change and dwindling oil reserves. A research article suggests that HE is wrong and SHE has the answer in the sustainable hydrogen economy.

A planet made of diamonds may sound lovely, but you wouldn't want to live there. A new study suggests that some stars in the Milky Way could harbor "carbon super-Earths" – giant terrestrial planets that contain up to 50 percent diamond. But if they exist, those planets are likely devoid of life as we know it.
