Article
Fraunhofer ISE has along experience in the fieldof surface passivation for crystalline silicon wafers. Novel rear-surface passivation layer systems have led to excellent results. Using a low-temperature passivation stack of hydrogenated amorphous silicon and plasma-enhanced chemical vapor deposition (PECVD) silicon oxide an efficiency of up to 21.7...
Conference Paper
Full-text available
Solar cells of "classic" external contact structure with front and rear contacts applying a passivated and locally contacted rear are presented in this paper. A variety of rear surface passivation schemes deposited by PECVD are discussed and compared using illuminated I-V, reflection and internal quantum efficiency measurements with fixed and varia...
Article
Full-text available
A novel plasma-enhanced chemical vapour deposited (PECVD) stack layer system consisting of a-:H, a-:H, and a-:H is presented for silicon solar cell rear side passivation. Surface recombination velocities below 60 cm/s (after firing) and below 30 cm/s (after forming gas anneal) were achieved. Solar cell precursors without front and rear metallisatio...
