Mainly due to the relatively low lying HOMO energy level (and hence high VOC of ∼1 V), such ηPC is superior to other electron donor materials, including long wavelength absorption pentacene and CuPc, or short wavelength absorption TDCV-TPA and TPTPA. NPAFN OPVs also may benefit from ...
However, the excitation wavelength of conPET systems mainly focused on short wavelength visible light, leading to photo- damage and incompatibility with large-scale reactions. Herein, we report on conPET systems triggered by near-infrared (NIR) and red light. Specifically, a blue-absorbing conPET...
there are cases where conversion effects are known to dominate (e.g., the Gulf of Maine22). Away from shelf seas and coastal waters, the total RMS variability in Fig.2shows long-wavelength features of order 1–2 mm (dashed contours), again manifesting a sensitivity to stratification changes...
to the fact that materials used in SLMs such as liquid crystals and quantum wells have a response that is highly wavelength-dependent. Materials developed for SLMs in the visible to short-wave infrared are thus generally unsuitable for the MWIR to LWIR. This has motivated investigations into ...
solution also removes a considerable fraction of the simulated baroclinic tide and its long-wavelength features, the remaining internal tide signals in the yearlyηmaps are relatively easy to suppress. For M2and S2, we have found a Hamming window with a cutoff wavelength of 390 km (100 km)...
Umklapp scattering typically affects high-energy phonons more; thus, the transmission of high-energy phonons is suppressed compared to that of acoustic long-wavelength phonons, to begin with. However, the main point is that the long-wavelength modes are highly resilient to nanostructuring compared to...
2.4. Photoelectric Conversion System Photovoltaic cells are required for photoelectric conversion systems to convert light energy into electricity. Figure 8 demonstrates the photovoltaic conversion efficiency of common photovoltaic cell materials as a function of wavelength [26]. Figure 8 shows that the ...
form suitable distributed Bragg reflectors. For example, to achieve the same reflectivity achievable with 30 mirror pairs of AlGaAs/AlAs (a common material family in the active region for short-wavelength VCSELS) at least 50 to 60 mirror pairs of materials in the InGaAsP system would be ...
Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II superlattice material....
