By switching catalyst from silver to copper, Natcore finds additional solar cell savings

Wednesday, September 10, 2014 - 04:40 in Physics & Chemistry

In making a solar cell, scientists etch nanoscale spikes into a silicon wafer in order to maximize its surface area and consequently to maximize the amount of sunlight to reach it. Metal particles have been used as a catalyst in this process because etching is much accelerated near metal particles.
