“…The analysis of the world data on the structure function ratios performed in this paper has demonstrated that the relativistic theory of nuclear binding [7] is in very good agreement with experiment. I observe also that the agreement is considerably better than that obtained by recent explanations of the EMC effect in the QCD inspired model [20] or in the phenomenological double Q 2 -rescaling model [21].…”

Nucleon structure function ratios r A (x) = F A 2 (x)/F D 2 (x) measured in the range of atomic masses A ≥ 4 are analyzed with the aim to determine the pattern of the x and A dependence of F 2 (x) modifications caused by nuclear environment. It is found that the x and A dependence of the deviations of the r A (x) from unity can be factorized in the entire range of x. The characteristic feature of the factorization is represented with the three cross-over points x i , i = 1 -3 in which r A (x) = 1 independently of A. In the range x > 0.7 the pattern of r A (x) is fixed with x 3 = 0.84 ± 0.01. The pattern of the x dependence is compared with theoretical calculations of Burov, Molochkov and Smirnov to demonstrate that evolution of the nucleon structure as a function of A occurs in two steps, first for A ≤ 4 and second for A > 4. The long-standing problem of the origin of the EMC effect is understood as the modification of the nucleon structure in the field responsible for the binding forces in a three-nucleon system.

“…[ 36 ] The penetrated water and oxygen will oxidize the metal electrode forming a metal oxide interlayer between the electrode and photoactive layer, [ 37 ] which hinders the charge injection at the interface and causes an S‐shaped J–V curve of PSCs. [ 50 ] When water and oxygen reach the electrode buffer layer, such as poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS), [ 51,52 ] MoO 3 , [ 53 ] ZnO, [ 54 ] LiF, and Ca, [ 55 ] both physical and chemical interactions of water and oxygen with these buffer layers will change the work function of the buffer layer and consequently decrease the device performance. Actually, diffusion of water and oxygen into the photoactive layer were also reported.…”

Although power conversion efficiency (PCE) of polymer solar cells (PSCs) has exceeded 18%, the lifetime of PSCs is far away from satisfactory and has become the most critical issue before the commercialization of PSCs. Understanding the degradation mechanism and finding the proper way to suppress the degradation process are of high interests for PSC research. Polymer:fullerene solar cells (PFSCs) have a long research history and the working principle is well‐understood, so they are good models for the degradation mechanism study. This mini‐review summarizes the latest research progress of the PFSCs’ degradation studies. Based on the results achieved, one can identify the extrinsic and intrinsic stress factors that cause different degradation processes. Degradation pathways of the PFSCs at different positions in the cells will be discussed in detail, including the electrode, the buffer layer, and the photoactive layer. Special emphasis will be put on various degradation processes of the photoactive layers. In the meantime, the methods to suppress the degradation processes will be presented accordingly. This mini‐review gives a comprehensive insight into the degradation mechanism and stability‐improvement strategies of PFSCs, which has important guiding significance for the stability‐improvement research of PSCs.
