The inverted polymer solar cell (PSC) based on a sol–gel derived zinc oxide (ZnO) thin film as an electron selective layer is investigated. The device performance is improved after the fabricated device is placed in air for a few days. The improvement is attributed to the self-organization of the poly(3-hexylthiophene)/[6,6]-phenyl-C 61 -butyric acid methyl ester layer and oxidation of the...
The inverted bulk hetero-junction solar cell on the polyester (PET) substrate with a non-annealing active layer is investigated. Our investigations show that the easily processed inverted device with a non-annealing active layer on the indium-tin-oxide coated PET substrate exhibits a high power conversion efficiency of ~3.65%.
Organic-inorganic hybrid solar cells as low-cost renewable energy sources have attracted great attention due to the possibility of fabricating them on large-area, light-weight, flexible substrates by printing and coating technologies. Hashimoto et al. investigated the performance dependence of poly(3-hexylthiophene) (P3HT): (6,6)-phenyl C61 butyric acid methyl ester (PCBM)/ZnO hybrid solar cells on...
We report electroluminescence from ZnO nanorod-based devices prepared by the hydrothermal method. The devices composed of ZnO nanorods and P3HT, in which ZnO acts as an n-type material and P3HT acts as a p-type material.
