How to convert US to 100 percent renewable energy

It’s technically possible for each state to replace fossil fuel energy with entirely clean, renewable energy, experts say. A new report is the first to outline how each of the 50 states can achieve such a transition by 2050. The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.

Finding a way to boost efficiency of CIGS solar cells

Researchers have revealed the structure of the buffer layer in a CIGS (copper-indium-gallium-selenide) solar cell at SPring8, the world’s largest third-generation synchrotron radiation facility. They found that the buffer layer was composed of two layers: an upper Zn(OH)2 layer and a lower Zn(S, O) layer. By removing the upper Zn(OH)2 layer, the solar conversion efficiency was doubled.
