Enhanced intraband absorption in two-step photon upconversion solar cells with a double-tunnel-junction structure
Koichiro Matsuzawa, Shigeo Asahi, Takashi Kita
Two-step photon upconversion solar cells (TPU-SCs) belong to the class of solar cells that in principle can exceed the Shockley--Queisser limit for single-junction solar cells. A T…
Conduction band resonant states absorption for quantum dot infrared detectors operating at room temperature
Stefano Vichi, Shigeo Asahi, Sergio Bietti +4
Long Wavelenght infrared devices, despite growing interest due to a wide range of applications in commercial, public, and academic sectors, are still struggling to achieve signific…
Microscopic observation of carrier-transport dynamics in quantum-structure solar cells using a time-of-flight technique
Kasidit Toprasertpong, Naofumi Kasamatsu, Hiromasa Fujii +7
In this study, we propose a carrier time-of-flight technique to evaluate the carrier transport time across a quantum structure in an active region of solar cells. By observing the…
