说明

在最近对双结量子点发光二极管 (QD-LED) 的研究中，实现了令人印象深刻的 42.2% 的高量子效率和 183.3 cd/A 的高电流效率，与现有的最好的真空沉积串联有机 LED。这种高效器件是通过完全优化的单个发光单元的界面工程来实现的，它改善了载流子的传输/注入平衡并抑制了由 ZnO 引起的激子猝灭，并设计了由 Poly-TPD 混合多聚 ( 9-乙烯基咔唑）（PVK）/聚（3,4-乙烯二氧噻吩）：聚苯乙烯磺酸盐/聚乙烯亚胺乙氧基化改性氧化锌。

室内光伏是低功耗电子产品（如快速发展的物联网）的最佳可持续和可靠能源之一。
在最近的另一项研究中，具有介孔 PPV (mPPV) 结构的钙​​钛矿光伏 (PPV) 电池使用典型的 Spiro-OMeTAD 作为空穴传输层 (HTL)，在 200 勒克斯和115.6 μWcm-2 1000 lux（无遮蔽）下，在室内光伏中名列前茅。当 PEDOT:PSS 被 Poly-TPD 取代为倒置 PPV (iPPV) 电池中的 HTL 时，室内光下的 Pmax 显着提高，与最好的介孔 mPPV 电池相当。

应用

In a recent study of a double-junction Quantum-Dot Light-Emitting Diodes (QD-LEDs), an impressive high quantum efficiency of 42.2% and a high current efficiency of 183.3 cd/A were achieved, which are comparable to those of the best vacuum-deposited tandem organic LEDs. Such high-efficiency devices are achieved by interface engineering of fully optimized single light-emitting units, which improves carriers′ transport/injection balance and suppresses exciton quenching induced by ZnO, and design of an effective interconnecting layer consisting of Poly-TPD mixed poly(9-vinylcarbazole) (PVK)/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate/polyethylenimine ethoxylated-modified ZnO.

Indoor photovoltaics is one of the best sustainable and reliable energy source for low power consumption electronics such as the rapidly growing Internet of Things.
In another recent study, Perovskite photovoltaic (PPV) cells with a mesoporous PPV (mPPV) structure using typical Spiro-OMeTAD as the hole transport layer (HTL) shows the highest maximum power density (Pmax) of 19.9 μW/cm2 under 200 lux and 115.6 μWcm-2 under 1000 lux (without masking), which is among the best of the indoor PV. When PEDOT:PSS is replaced by Poly-TPD as HTL in the inverted PPV (iPPV) cell, the Pmax under indoor light improves significantly and is comparable to that of the best mesoporous mPPV cell.
