Non-imaging optical concentrator

A solar cell, comprising:

• a substrate;
• a solar cell disposed over the substrate;
• and
• a non-imaging optical concentrator optically aligned with the solar cell,
• wherein the non-imaging optical concentrator is configured to concentrate an incident light received by the non-imaging optical concentrator on the surface of the solar cell, and
• wherein the non-imaging optical concentrator comprises:
• a top portion,
• a body, and
• a bottom portion,
• wherein the top portion is configured to receive an incident light and transmit the received incident light to the body when the incident light is within an angle of acceptance for the non-imaging optical concentrator, and
• where the body is configured to reflect the incident light transmitted by the top portion to the bottom portion when the incident light is within the angle of acceptance for the non-imaging optical concentrator, and
• wherein the top portion is configured to split the incident light into two or more directions, and wherein the body comprises one or more non-reflecting portions that do not reflect the incident light transmitted by the top portion to the bottom portion when the incident light is within the angle of acceptance for the non-imaging optical concentrator.
