Method for forming photovoltaic cell, and resulting photovoltaic cell
摘要:
A photovoltaic cell manufacturing method is disclosed. Methods include manufacturing a photovoltaic cell having a selective emitter and buried contact (electrode) structure utilizing nanoimprint technology. The methods include providing a semiconductor substrate having a first surface and a second surface opposite the first surface; forming a first doped region in the semiconductor substrate adjacent to the first surface; performing a nanoimprint process and an etching process to form a trench in the semiconductor substrate, the trench extending into the semiconductor substrate from the first surface; forming a second doped region in the semiconductor substrate within the trench, the second doped region having a greater doping concentration than the first doped region; and filling the trench with a conductive material. The nanoimprint process uses a mold to define a location of an electrode line layout.
