Two-photon photocurrent in InGaN/GaN nanowire intermediate band solar cells

Intermediate band solar cells have the ability to reach efficiencies similar to multijunction cells using a single semiconductor junction. Here, enhanced two-photon carrier generation is demonstrated on a silicon substrate in an InGaN/GaN quantum dot-in-nanowire heterostructure intermediate band sol...

Sumario:Intermediate band solar cells have the ability to reach efficiencies similar to multijunction cells using a single semiconductor junction. Here, enhanced two-photon carrier generation is demonstrated on a silicon substrate in an InGaN/GaN quantum dot-in-nanowire heterostructure intermediate band solar cell.
