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.
Scientists have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing technique to form the cathode material into tiny, layered particles that store a lot of energy while protecting themselves from damage.
