Novel deposition method of anti-reflective coating for spherical silicon solar cells

The liquid-phase deposition (LPD) as a novel deposition method of anti-reflective coating (ARC) for spherical silicon solar cells has been proposed. The LPD is a growth method in aqueous solution and can deposit thin films with uniform coverage over a spherical surface. The solar cell performance of the spherical silicon solar cell with an ARC shows more than 10% increase in short-circuit current density compared to that without an ARC. The result confirms that the LPD method is useful for ARC fabrications of spherical silicon solar cells.
