n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

Advanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

Bandgap Reference Voltage Generator

, 2007
　　準確的參考電壓源在現今的積體電路系統中扮演相當重要的角色，它能產生一穩定的參考電壓，不因電源電壓及環境溫度的變化而產生太大的變動，以提供系統作為比較或維持電路正常操作之用。參考電壓源的應用相當廣泛，常見用於類比-數位或數位類比轉換器、運算放大器或線性穩壓器中，提供設定輸入或輸出電壓範圍、差動輸入對之電流源偏壓或作為比較器的參考電壓等等。 　　本論文主要目的為設計一可操作在輸入電壓3V-6V而輸出電壓約1.25V的能隙參考電壓產生電路，提供一穩定的參考電壓給低壓降線性穩壓器使用 ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

Advanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.
