Bulk-heterojunction organic solar cells (OSCs) based on poly(3-hexylthiophene) as a donor material and (6.6) phenyl-C61-butyric acid methyl ester as an acceptor material were investigated using a poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) buffer layer that was modulated with acetic acid. The 1.

We applied high pressure to PbS CQD solids using nitrogen gas to reduce the inter-dot distance. Using this simple process, we obtained conductive PbS CQD solids.

In this study, we investigated hybrid bulk heterojunction organic solar cells containing ZnO nanoparticles blended with poly(3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) and having poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) or N,N-dimethylformamide (DMF)-modulated PEDOT:PSS buffer layers. The reference cell, which had a P3HT:PCBM active layer sandwiched between ITO\PEDOT:PSS and LiF\Al electrodes, exhibited an efficiency of 1.55%.
