The optimisation of amorphous silicon layers (a-Si:H) is of key importance to obtain high efficiency heterojunction (HJ) solar cells. However, since many mechanisms take place in photovoltaic energy conversion, good electrical and optical properties of a-Si:H films do not always result in high efficiency HJ devices. This is principally due to the use of very thin layers were interfaces are of capital...
In this work, we have studied the scalability of our fabrication process for heterojunction solar cells up to 148.5 cm2 total area. Double heterojunction devices were fabricated on both n- and p-type textured substrates using only doped (n) and (p) a-Si:H layers. ITO was used as anti-reflective coating and evaporated Aluminum as the metallic back contact. Finally, an Ag grid was screen-printed at...
The authors report record performances for the reliability of amorphous silicon (a-Si:H) photosensor under high flux illumination. A fully functional VGA (3.0 mum pitch) image sensor, which can withstand 90 suns (= 9 Mlux) during 26 ks, was realized by the optimization of a-Si:H parameters, the pixel structure and the reading voltage
