Abstract :
Intrinsic microcrystalline silicon has been deposited by very high frequency plasma enhanced chemical vapor deposition technique at
frequency of 75 MHz. Different gas mixtures of silane and hydrogen were utilized, and the evolution of microstructure and phase in film
were studied, while keeping the substrate temperature at 200 C and the chamber pressure at 0.5 Torr. Optimised material was inserted in
p–i–n solar cells: preliminary efficiency of 5.5% was reached for 1 lm-thick solar cells with the Voc around 0.6 V.
