Although the cell cycle normally progresses from G1toStoG2toM and then back to G1, certain manipulations have been found to ''short circuit'' the cycle, causing repetitions of some stages while skipping others. A new study suggests how these changes limit the actions of molecular ''latches'' that normally ensure orderly cell cycle progression.

Recently, a lot of research focus has been on how to make solar cells more efficient. One direction is to enhance the open-circuit voltage V oc by optimizing the emission of photons in the cell, where emission is a necessary loss process due to the reciprocity between absorption and emission of light. ...
#1 Prevent cell-to-cell propagation It may not be possible to eliminate the possibility of thermal runaway within a cell completely. While good thermal management, structural design, and battery management can reduce the risk, there is always the possibility of defects or foreign objects causing internal short circuits.
Background Solar cell/supercapacitor integrated devices (SCSD) have made some progress in terms of device structure and electrode materials, but there are still many key challenges in controlling electrode performance and …

Strikingly, the open-circuit voltage (V oc) of the PBDB-T:ITIC solar cell based on ZnO is high, over 1.0 V, which is a record value for PBDB-T:ITIC solar cells 64, whereas the V oc of the ITO ...
The inevitable energy loss (Eloss) in organic solar cells (OSCs) makes it a challenge to simultaneously enhance the open-circuit voltage (VOC) and short-circuit current (JSC). Herein, we designed and …
The performance of solar cells based on molecular electronic materials is limited by relatively low open-circuit voltage (Voc) relative to the absorption threshold. These voltage losses must be reduced to achieve competitive power-conversion efficiencies. Voltage losses are assigned to the molecular heterojunction required to dissociate …
1 Introduction The efficient conversion of solar radiation into electrical power by a solar cell requires absorbing the photons, creating charge carriers, collecting them at the junction and finally doing so at a nonzero free energy per extracted charge carrier. 1-3 In order to compare the ability of a solar cell to generate a high free energy …
