Abstract
A novel photovoltaic solar cell and method of making the same are disclosed. The solar cell includes: at least one absorber layer which could either be a lightly doped layer or an undoped layer, and at least a doped window-layers which comprise at least two sub-window-layers. The first sub-window-layer, which is next to the absorber-layer, is deposited to form desirable junction with the absorber-layer. The second sub-window-layer, which is next to the first sub-window-layer, but not in direct contact with the absorber-layer, is deposited in order to have transmission higher than the first-sub-window-layer.

A method for manufacturing a solar cell comprising the steps of:
- (i) providing a transparent substrate;
- (ii) depositing a transparent conducting oxide layer on the substrate;
- (iii) depositing a second sub-p-layer on the substrate at a temperature relatively low for improved transparency of the second sub p-layer;
- (iv) depositing a first sub-p-layer on the second sub-p-layer at a relatively higher temperature to form a good junction with an i-layer to be deposited thereon;
- (v) depositing the i-layer on the first sub-p-layer at a temperature sufficiently low to avoid melting or damaging the p-layer;
- and
- (vi) depositing a layer of n-type semi-conductor on the substrate at a temperature sufficiently low to avoid damage or melting the p and i-layers.
