ENHANCING SOLAR
CELL PERFORMANCE
One way to improve the light absorption of solar cells is to create
anti-reflection material layers on the photovoltaic wafer. However,
all the possible approaches—multilayer dielectric film, nanoparticle
sludges, microtextures, and 3D silicon nanostructure arrays, to name
a few—are costly and often times incompatible with industry standards. ECE Associate Professor Gang Logan Liu has developed a
new nano-manufacturing technique called Simultaneous Plasma-Enhanced Reactive Ion Synthesis & Etching (SPERISE) that offers a better anti-reflection solution while possibly increasing the p-n junction
surface area. SPERISE improv
