ABSTRACTA thin multi-layered photoreceptor drum has been fabricated, using glow-discharge decomposition of disilane. The photoreceptor is thin(10 μm), but it is charged up sufficiently. The photoreceptor has three layers; the p-type a-Si:H (blocking layer), the intrinsic B-doped a-Si:H (photoconductive layer) and a-SiC:H (passivation layer). Disilane is highly reactive. The intrinsic B-doped a-Si:H was prepared from a slightly gaseous mixture of B2H6 (3 ppm). The amorphous-SiC:H passivation layer deposited from Si2H6 and C3H8 was developed to achieve sufficient surface potential and to improve the environmental characteristics.

ABSTRACTBasic technologies for solving problems in thermal and light-induced degradation have been developed. The tandem type a-SiC/a-Si solar cell with blocking layers exhibits excellent stability for both thermal and sun light conditions. An observable light-induced degradation is not seen in the cell performance after light exposure test of 2000 hours. Two instability modes, that is, thermal and light-induced degradation have been investigated. For thermal degradation, a blocking layer for preventing diffusion has been inserted between the back side metal electrode and a n-layer and another blocking layer has been introduced between the np tunnel junction. To prevent light-induced degradation, p-type a-SiC layer of the pin structure on the side of a glass substrate/SnO2 has been deposited at the temperature of 70°C. The highest efficiency is 9.0% at the present stage, but it is expected to be improved to more than 10%.

ABSTRACTLiquid crystal light valve(LCLV) using an a-Si:H/μc-Si:H heterostructure as the photosensor and the nematic liquid crystal as the modulator has been firstly presented for large screen projection display. The a-Si:H photoconductor and μc-Si:H light blocking layer were prepared by a modified glow discharge CVD method. The optoelectric and structure properties of the μc-Si:H films deposited at different deposition conditions have been studied. The a-Si:H film and the continuously deposited pc-Si:H film possibly form an a-Si:H/μc-Si:H heterojunction. The electrical and optoelectric properties of the heterojunction has been studied.LCLV using a-Si:H/μc-Si:H heterostructure has shown that the most aspects of the device performance can be improved.

Glow Discharge Plasma

A traditionally unperceived approach, glow discharge plasma, is employed to modify the surface of Mo2C@NCF. The plasma breaks the MoOx passivation layer on Mo2C and promotes the formation of interfacial Mo–N, leading to enhanced cycling durability.
