A comparative study of photoconductivity and carrier transport in a-Si:H p–i–n solar cells with different back contacts

Preparation of crystalline zinc oxide films by one-step electrodeposition in Reline

“…It is highly conductive, stable in air and water, and has a 2.5 V electrochemical window. ZnO thin films have been extensively used as n-type transparent semiconductor layer in solar cells [1][2][3][4][5].…”

Bragg mirrors porous silicon back reflector for the light trapping in hydrogenated amorphous silicon

“…As a consequence, the photodetectors that are fabricated from this material, exhibit low dark current and high photosensitivity. They have been developed for several applications such as thin solar cells and sensors [12,13]. The photosensitivity of the electrical properties of a-Si:H thin films result from its high absorption coefficient of visible light in particular in the blue.…”
