Electroplating of aluminum may be utilized to form electrodes for solar cells. In contrast to expensive silver electrodes, aluminum allows for reduced cell cost and addresses the problem of material scarcity. In contrast to copper electrodes which typically require barrier layers, aluminum allows for simplified cell structures and fabrication steps. In the solar cells, point contacts may be utilized in the backside electrodes for increased efficiency. Solar cells formed in accordance with the present disclosure enable large-scale and cost-effective deployment of solar photovoltaic systems.
An electroplating method, comprising:
The method of claim 14, wherein the first dopant is boron.
The method of claim 14, wherein the first dopant has a doping concentration of about 1×1016 cm−3.
The method of claim 14, wherein the second dopant is phosphorus.
The method of claim 14, wherein the second dopant is arsenic.
The method of claim 14, further comprising using laser ablation or photolithography to texture the P-type silicon wafer.
The method of claim 14, wherein the P+ back surface field has a depth of between 7 and 13 micrometers.
Dependencies are inferred from the claim text.
