Light emitting, photovoltaic or other electronic apparatus and system

An apparatus, comprising:

• a base;
• at least one first conductor coupled to the base;
• a plurality of diodes coupled to the at least one first conductor, wherein about fifteen percent to fifty-five percent of a surface of each diode of substantially all of the plurality of diodes has a penetration layer or region having a first majority carrier or dopant and the remaining diode substrate has a second majority carrier or dopant;
• at least one second conductor coupled to the plurality of diodes;
• and
• a plurality of lenses suspended in a first polymer and coupled to the plurality of diodes.

A system, comprising:

• an electrical or electronic interface;
