Organic solar cells and methods of making the same
摘要
說明書
As used herein, the term “about” will be understood by persons of ordinary skill in the art and will vary to some extent depending on the context in which it is used. As used herein when referring to a measurable value such as an amount, a temporal duration, and the like, the term “about” is meant to encompass variations of ±20% or ±10%, more preferably ±5%, even more preferably ±1%, and still more preferably ±0.1% from the specified value, as such variations are appropriate to perform the disclosed methods.
As used herein, the term “substrate” refers to a structural surface beneath a layered material or coating (e.g., polymer coating).
As used herein, the term fullerene, buckminsterfullerene (C60) and associated, including “spherical” fullerenes and carbon nanotubes, include various cage-like molecules consisting only of carbon. For example, fullerenes can be selected by those skilled in the art in the range of C20-C1000. In some embodiments, the fullerene is selected from the range C60 to C96. In other embodiments, the fullerenes are C60 or C70. Chemically modified fullerenes typically have more preferable solubility characteristics and are thus applied in photovoltaic devices as would be understood by those skilled in the art.
