Incorporating ZnO Nanoparticles with PC61 BM as Electron Transporting Layer for Perovskite Solar Cells
No full textThe word record power conversion efficiency (PCE) of photovoltaic devices based on organometal halide perovskite materials all around the world has reached to over 25% because of the excellent properties of the perovskite materials. However, most of the perovskite solar cells (PSCs) with PCE higher than 20% are based on a normal n-i-p structure using TiO2 electron transporting materials which require high-temperature (500 degrees C) thermal annealing. To develop a low-temperature device fabrication process, an inverted PSC with p-i-n structure has been manufactured. However, the PCE of PSCs with this structure is relatively lower than that of normal n-i-p structure. Herein, we have assembled and investigated the photovoltaic performance of the PSCs with the structure of FTO Glass/NiO/Perovskite/PC61 BM/BCP/Ag. It is found that the PCE of the PSCs is strongly dependent on the fabrication conditions of the PC61BM. The champion device can be obtained by optimizing the concentration of PC61BM of 25 mg/mL in chlorobenzene (CB). We found that the V-oc of the PSC is too low when the PC61BM is too thin, while the J(sc) is reduced when the PC61BM is too thick P: 111.93 14 78 On: Fr 15 Jan 2021 2:12:15 due to its low mobility. To solve this problem, we mxed the PC61BM wtZnO nanoparticles which has higher Copyright: American Scientific Publish ers electron mobility. Interestingly, the PSC based on a PC61BM/ZnO blend layer has a higher PCE of 13.2%.

No full textMice lacking C1q or C3 show accelerated rejection of minor H disparate skin grafts and resistance to induction of tolerance
No full textComplement activation is known to have deleterious effects on organ transplantation. On the other hand, the complement system is also known to have an important role in regulating immune responses. The balance between these two opposing effects is critical in the context of transplantation. Here, we report that female mice deficient in C1q (C1qa(-/-)) or C3 (C3(-/-)) reject male syngeneic grafts (HY incompatible) at an accelerated rate compared with WT mice. Intranasal HY peptide administration, which induces tolerance to syngeneic male grafts in WT mice, fails to induce tolerance in C1qa(-/-) or C3(-/-) mice. The rejection of the male grafts correlated with the presence of HY D(b)Uty-specific CD8(+) T cells. Consistent with this, peptide-treated C1qa(-/-) and C3(-/-) female mice rejecting male grafts exhibited more antigen-specific CD8(+)IFN-gamma(+) and CD8(+)IL-10(+) cells compared with WT females. This suggests that accumulation of IFN-gamma- and IL-10-producing T cells may play a key role in mediating the ongoing inflammatory process and graft rejection. Interestingly, within the tolerized male skin grafts of peptide-treated WT mice, IFN-gamma, C1q and C3 mRNA levels were higher compared to control female grafts. These results suggest that C1q and C3 facilitate the induction of intranasal tolerance.</p
