abstract = {A 13.56 MHz parallel plate hydrogen-diluted silane plasma,
operated at high pressure and high power, was used to
deposit microcrystalline silicon solar cells with
efficiencies of $6-9\%$ at high deposition rates of 0.4-1.2
nm/s. In this regime new challenges arise regarding
temperature control, since the high plasma power causes the
substrate to heat up significantly during film deposition.
We investigated this effect of plasma-induced substrate
heating experimentally by means of pyrometric substrate
temperature measurements and spectroscopic gas temperature
measurements. The substrate temperature was observed to
increase by up to 100 K during film deposition, depending on
power density and deposition time. Performance of deposited
solar cells decreased whenever the plasma induced heating
caused a drift outside the ideal temperature window, of
around 475 K (similar to 206 degrees C). Further analysis
related this decrease in performance to the substrate
temperature's influence on film crystallinity and open
circuit voltage. (c) 2005 Elsevier B.V. All rights
