“…In addition to the packing of the molecules in the monolayer and surface energy, the orientation of the polarizable phenyl ring can affect the induced surface dipole 43 or the effective work function, a critical parameter in the performance of several semiconductor devices, such as diodes and solar cells. 44 Table 2 lists the contact potential difference of the C n Bz-modified Si in relative values and its translation to estimated absolute work-function values.…”

“…Here, as the free energy of the process, given by E CT , increases, the recombination rate decreases, which in turn increases the and results in higher voltage efficiency 53 . Energetic disorder at the interfaces and in the bulk, including structural disorder 54,55 also add to the non-radiative recombination. In an organic blend, energy back transfer from the CT state to the Donor material can happen, which enables electron-hole recombination to proceed via electronic states of the pristine organic material 56 .…”

“…It is therefore possible to observe carrier generation, transport and recombination dynamics in these systems. 57 Fig. 4 shows the TPC traces for each of the four different types of cells (with the different metal oxides exhibiting low and high surface hydrogen content in each case), while they are operating at their maximum power (500 mV applied bias).…”

“…[4][5][6][7][8] Critical to these processes is the nanomorphology of the blend; this places a pressing challenge on the science of OSC materials and devices, as we have to be able to determine and control how the two materials mix together or segregate. [6][7][8][9][10][11][12][13][14][15][16][17][18] The goal of manipulating the nanomorphology of organic photovoltaic blends can be reached using a heuristic fashion of processing approaches, namely by applying a post-annealing process, varying the polymer blend ratio, solvent choice, solution concentration, film drying time and co-solvent/processing aids. [19][20][21][22][23][24][25][26][27][28][29][30] In the commonly used blend of regioregular poly(3-hexythiophene) (P3HT) and [6,6]-phenyl C 71 butyric acid methyl ester (PC 71 BM), the most effective strategy toward constructing the nanoscale D/A percolated networks with well-optimized morphology is the application of a post annealing treatment at high temperatures.…”
