28 Sep 1971TL;DR: In this article, a fine geometry solar cell with a top surface contact comprising more and finer metallic fingers spaced close together for collecting photocurrent was proposed. But the method for making the fine geometry photonic solar cell, comprises in ordered steps, the processes of diffusion, oxidation, photolithography, metallization and plating.
Abstract: A fine geometry solar cell having a top surface contact comprising substantially more and finer metallic fingers spaced close together for collecting photocurrent. Junction depth and/or impurity concentration may be reduced significantly. The method for making the fine geometry solar cell, comprises in ordered steps, the processes of diffusion, oxidation, photolithography, metallization and plating.

03 Dec 1971TL;DR: In this paper, a metal layer is added to the P-N junction of a solar cell to reflect back towards the junction light which would otherwise penetrate too deeply to contribute to the voltage and current output.
Abstract: The efficiency of a solar cell is improved by incorporating a metal layer beneath the P-N junction of the solar cell. The metal layer reflects back towards the junction light which would otherwise penetrate too deeply to contribute to the voltage and current output. The metal also produces charge carriers which are photo excited up to the conduction band of the semiconductor by light having photon energy less than the semiconductor band gap. The metal and the semiconductor material forming the solar cell are both highly ordered, thereby forming a barrier contact at the metal-semiconductor interface.
