N2 - In this work, we report on the last investigations of (n+) a-Si:H / (p) c-Si heterojunction solar cells deposited by both HWCVD and PECVD. Regarding HWCVD films, we use Spectroscopic Ellipsometry measurements to characterize the material properties of the deposited films. Particularly, we study the effect of the (i) a-Si:H film on the (n+) a-Si:H film growth. As far as PECVD films are concerned, an optimum PH3 flow is determined from the point of view of dark conductivity. Additionally, QSS-PC measurements are used to determine the improvement in the passivation quality of this film. Finally, HWCVD and PECVD HIT emitters are compared. A high quality in both emitters is deduced with implied Voc values exceeding 665 mV.
