WebAs high as 54% reflectance at 1200 nm indicates that the a-Si:/SiNx:H stack acts as a good rear reflector when combined with an overlying thin layer of Al. The third part of this work focuses on developing a rear localised metal contact in conjunction with the a-Si:H/SiNx:H passivated rear surface, based on laser-doping combined with a low temperature … Web5 jun. 2015 · Under the right conditions there can be significant advantages to operating multiple stages in the transmitter with dynamic power supplies. And under the wrong conditions, an attempt to operate multiple stages as a DPS transmitter can be disastrous. In this chapter, both situations are encountered. The basic architecture is straightforward, …
