1. A method for manufacturing a solar cell comprising the steps of:

  • (i) providing a substrate;

    (ii) depositing a layer of n-type semi-conductor on the substrate at a temperature that is one of 300°

    C. and sufficiently low to avoid damage or melting the substrate;

    (iii) depositing an i-layer on the n-layer at a temperature that is one of 300°

    C. and sufficiently low to avoid melting or damaging the n-layer;

    (iv) depositing a first sub-p-layer on the i-layer at a first temperature sufficiently high to form a good junction with the i-layer; and

    (v) depositing a second sub-p-layer on the first sub-p-layer at a temperature lower than the first temperature at which the first sub-p-layer is deposited.
