摘要
Abstract The rectenna solar cell is considered to be one of the best photovoltaic devices due its effective light to electric energy conversion performance. New ideas are needed to improve the design of efficient rectenna solar cells. In this paper, we have described a novel design of an antenna associated with a rectifier. Solar spectrum contains radiation of different wavelengths and intensities. The intensity of solar radiation is maxima at around the 500 nm wavelength. The monopole antenna of the length 125 nm (dipole of the length 250 nm) converts the maximum energy of the solar spectrum. Metallic behaving nano rods may be better as the antenna. The carriers of the nano rod should remain free from any bias for highly efficient rectenna solar cells. The pn junction should be used as a rectifier in the rectenna solar cells to get better receiving power. The rectifier(s) position may keep a role to increase the receiving power. Furthermore, we proposed some important analytical investigations that could help to optimize the antenna carrier density.
