Demonstration of a 33% Efficient Cassegrainian Solar Module

Demonstration of a 33% Efficient Cassegrainian Solar Module

The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is repor...

Zusammenfassung:The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual junction (DJ) cells located at the near-visible focus at the center of the primary and GaSb infrared solar cells located behind the secondary
