Small, Volume 22, Issue 48, 26 August 2026.PPV‐M, an amorphous electron transporting polymer with a high Tg of 118°C, suppresses thermally induced molecular diffusion in organic solar cells. Unlike crystalline PDINN (Tg = 61°C) with a T80 of only 8 h, PPV‐M maintains efficient electron extraction and extends T80 to 637 h, representing an 80‐fold enhancement in thermal stability.

IET Power Electronics, Volume 19, Issue 1, January/December 2026.This article presents a dual‐source novel nine‐level inverter (DSN2LI) featuring minimal devices. Utilizing eight switches, which include 2 bidirectional switching devices and 2 uneven dc links, the proposed DSN2LI generates nine levels. The DSN2LI employs the utilization of trinary geometric DC links.
