Management of singlet and triplet excitons for efficient white organic light-emitting devices
Yiru Sun,Noel C. Giebink,Hiroshi Kanno,Biwu Ma,Mark E. Thompson,Stephen R. Forrest,Stephen R. Forrest +6 more
TL;DR: This device challenges incandescent sources by exhibiting total external quantum and power efficiencies that peak at 18.7 ± 0.6 lm W-1, respectively, and two distinct modes of energy transfer within this device serve to channel nearly all of the triplet energy to the phosphorescent dopants, retaining the singlet energy exclusively on the blue fluorescent dopant.

Journal ArticleDOI
Red organic light-emitting diodes using an emitting assist dopant
TL;DR: In this paper, an EA dopant system for obtaining organic light-emitting diodes (OLEDs) with pure red emission was proposed, which did not itself emit but assisted the energy transfer from the host (Alq3) to the red emitting dopant (DCM2).
Journal ArticleDOI
Twenty-two percent efficiency HIT solar cell
Yasufumi Tsunomura,Yukihiro Yoshimine,Mikio Taguchi,Toshiaki Baba,Toshihiro Kinoshita,Hiroshi Kanno,Hitoshi Sakata,Eiji Maruyama,Makoto Tanaka +8 more
TL;DR: In this article, the authors achieved the world's highest solar cell conversion efficiency of 22.3% by using a heterojunction with intrinsic thin layer (HIT) structure, which is the first practical-size (>100 cm2) silicon solar cell that exceeds a conversion efficiency as a confirmed value.
Journal ArticleDOI
Green fluorescent organic light-emitting device with external quantum efficiency of nearly 10%
TL;DR: In this paper, a green fluorescent organic light-emitting device (OLED) exhibiting a high external quantum efficiency of nearly 10% has been developed, which consists of simple three organic layers, using NPB, 0.8% C545T doped TPBA, and DBzA as a hole-transporting layer, an emitting layer, and an electron-transport layer, respectively.
