Abstract: All day long the transportation infrastructure receives solar energy from the sun rays, storing much of them as heat that is left to dissipate by nightfall. The concept of harvesting solar energy from transportation infrastructure is enticing because it offers a way to collect solar energy by utilizing an extensive infrastructure that already exists. Thus, an attempt was made to investigate novel methods for solar energy harvesting and conversion with potential economic efficiency substantially beyond that of current technology. Particularly, a comparative study was conducted between rigid and flexible solar panels.

Abstract: Al doped zinc oxide (AZO) as anode for bulk-heterojunction [regioregular of poly(3-hexylthiophene) (P3HT):(6,6)-phenyl C61 butyric acid methyl ester (PCBM)] organic solar cells was investigated. We got efficient flexible solar cells with a highly transparent and electrical conductive NiO film as hole-transporting layer (HTL) on optimized AZO substrate. The strcture of this kind of devices is PET/AZO/NiO/P3HT: PCBM /Al. The highest power conversion efficiency (PCE) on glass substrate is 3.15%, and 1.66% on flexible substrate. The physical and electrical properties of AZO thin film were discussed, and the device photovoltaic characteristics were investigated in detail.

Abstract: A new buffering layer(nickle oxide thin film) of organic solar cells was presented. The device strcture is Anode/NiO/P3HT[regioregular of poly(3-hexylthiophene)]: PCBM[(6,6)-phenyl C61 butyric acid methyl ester] /Al. Nickle Oxide(NiO) thin film is a good alternative of hole tansporting layer. We investigates the film from physical and electrical aspects, such as morphology, deposition temperature, thickness etc. The best power conversion efficiency of device we got with NiO buffering layer is 2.49%, which is hundred times of ones without NiO buffering layer.We find that the optimum fabrication conditions are: room temperature deposition, 10nm of thickness, and 30% oxygen proportion.

Abstract: Novel types of solar cells based on nanostructured materials are intensively studied because of their prospective applications and interesting new working principle – essentially due to the nanomaterials used They have evolved from dye sensitized solar cells (DSSC) in the quest to improve their behavior and characteristics. Their nanocrystals (ca. 10-50 nm) do not generally show the confinement effect present in quantum dots of size ca. 1-10nm where electron wave functions are strongly confined originating changes in the band structure. Nonetheless, the nanocrystalline character of the semiconductor used determines a different working principle; which is explained, although it is not completely clear so far,. Different solid nanostructured solar cells are briefly reviewed together with research trends. Finally, the influence of the photoelectrode electron-extracting contact is analyzed.
