Imec Simplifies i-PERC Solar Cell Processing by implementing laser doping from ALD-Al2O3

November 29, 2013

Leuven (Belgium), November 27, 2013—Nanoelectronics research centre imec announced today that they have developed large area (156x156mm2) i-PERC-type silicon solar cells using a new processing sequence based on laser doping from a thin atomic layer deposited (ALD) aluminum oxide (Al2O3) layer to realize the local aluminum Back Surface Field (BSF) and Ni/Cu plating to form the front contact. The cells achieved average conversion efficiencies of 20.2%.

The new laser doping processing sequence eliminates the necessity of a firing step to create the local BSF in i-PERC solar cells. Combined with imec’s Ni/ … Read More → "Imec Simplifies i-PERC Solar Cell Processing by implementing laser doping from ALD-Al2O3"

SiC MOSFET-based Power Modules Utilizing Split Output Topology for Superior Dynamic Behavior

November 29, 2013

Unterhaching, Germany, 28th November 2013 – The body diode reverse recovery charge of a SiC MOSFET is lower than that of an Si MOSFET, but still not as beneficial as with SiC Schottky diodes. As the switching performance demands for new wide band-gap components increases, so do the requirements for the commutation process. The split output topology provides an additional tool to reduce turn-on losses and boost cross-conduction suppression. Installed at the module level it negates the limitations of the SiC MOSFET. The module behaves in inverter applications in the same way as in a boost circuit. This makes it possible … Read More → "SiC MOSFET-based Power Modules Utilizing Split Output Topology for Superior Dynamic Behavior"
