Title:
PHOTOVOLTAIC MULTI-JUNCTION THIN-FILM SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2011/091967
Kind Code:
A3
Abstract:
The invention relates to a photovoltaic multi-junction thin-film solar cell, comprising a carrier substrate (1) as well as at least one upper and one lower sub-cell, each of which is designed as a p-i-n structure that comprises a p-conducting layer (p-layer), an n-conducting layer (n-layer) and an intrinsic layer (i-layer) arranged between the p- and n-layers. Starting from a front face of the thin-film solar cell designed for light incidence, first of all the upper sub-cell (3), in which the i-layer is made of hydrogenised amorphous silicon, is arranged on the carrier substrate and/or on one or more further layers, and furthermore, below the upper sub-cell, the lower sub-cell (5) is arranged optionally on one or more further intermediate layers. In each sub-cell, the p-conducting layer is arranged on the face facing towards the front face. It is important in the case of the lower sub-cell that the i-layer is made of microcrystalline germanium.
