摘要：

Recently, an innovative silicon solar cell structure has been developed at ISFH which is capable of achieving very high cell efficiencies on industrial-size wafers with a simple photolithography-free processing sequence. As the corresponding solar cells essentially rely on the application of obliquely evaporated contacts they are denoted as OECO cells. In this paper the successful up-scaling of the novel OECO process from 21% efficient 4cm(2) laboratory devices to the fabrication of large-area (greater than or equal to 100cm(2)) silicon solar cells is described, and independently confirmed total area efficiencies of 20% are reported for 10 x 10cm(2) OECO-type solar cells fabricated on p-type float-zone silicon.
