Researchers from the United States have used new passivated contact architectures to demonstrate a screen-printed silicon heterojunction solar cell on 40 micron thick standalone wafers.A research team from the Solar Power Laboratory of the Arizona State University claim to have demonstrated a screen printed 40 micron thick silicon heterojunction solar cell, with an efficiency of 20.48%. The cell, described in the paper Improving surface passivation on very thin substrates for high efficiency silicon heterojunction solar cells, published in Solar Energy Materials and Solar Cells, is based on an ...Den vollständigen Artikel lesen ...
