Metal trace fabrication for optical element

摘要

A system may include a solar cell comprising a first electrical contact, an optical element comprising a second electrical contact, and a solder bump in contact with the first electrical contact and the second electrical contact. The solar cell is to generate charge carriers in response to received photons. Some aspects provide fabrication of a solder bump on an electrical contact of a solar cell, placement of the solder bump in contact with an electrical contact of an optical element, and melting of the solder bump to couple the electrical contact of the solar cell to the electrical contact of the optical element.
