Washington, June 20 (IANS): The more light a solar panel's active elements absorb, the more power it produces. So, researchers have now replaced a two-step process for producing black silicon - highly efficient materials that reflect almost no light - with one.
Black silicon lets maximum amount of sunlight reach a solar cell. It is simply silicon with a highly textured surface of nanoscale spikes or pores that are smaller than the wavelength of light.
The texture allows efficient collection of light from any angle - from sunrise to sunset.
