Xu et. al have synthesized the TiO2 film by mixing of TiO2 nanoparticles were in ethanol with different amounts of Triton-X100 and acetylacetone. The amounts of ethanol were 20, 40, and 60mL respectively. The amounts of acetylacetone were 0.4, 0.6, and 0.8mL. The sputtered Pt counter electrodes were pressed tightly on the prepared photoelectrodes. Solvent, dispersant, and surfactant play different roles in forming porous films of DSSCs when they are added into the paste. DSSC with the photoelectrode made from 2.5g of TiO2 nanoparticle powder dissolved in 20mL of ethanol containing 0.8mL of acetylacetone and 0.6mL of Triton-X100 shows a large increase in Jsc and a improvement in Voc. At the optimized point, photoelectric conversion efficiency …show more content…
The transmittance of ZnO passivating layers(ZNP) strongly depend on RF-gun power. Compared with the DSSC prepared without a passivating layer, the DSSC with ZNP layers demonstrated a high fill factor and high conversion efficiency. The DSSC with the ZNP layer, deposited under the 1:1 argon-oxide ratio, showed a high photocurrent density and a high fill factor (10.74 mA/cm2,72%). The DSSC fabricated onto the FTO electrode with the ZNP layer showed the highest conversion efficiency of 5.22% at an Ar: O2 ratio of 1:1, due to the prevention of the electron transfer to the electrolyte. Additional Ar: O2 ratios (1:0, 2:1, 1:2, 0:1) resulted in a decrease in efficiency and photocurrent density. Additionally, 80 W was the ideal RF-power. The improved conversion efficiency might be associated with improved surface roughness …show more content…
In XRD, it is observed that amorphous nature of dye films increases with fluence and hence aggregates of dye molecules spread homogeneously on the substrate after irradiation .The absorption spectroscopy and photoconductivity results show maximum absorption and minimum photoresistivity at lowest fluence [97]. The properties of the dye films such as increase in amorphous nature, increase in absorption peak area and marginal increase in photoconductivity are favorable for DSSC
Jedda Colonialism and Assimilation in Australian Film In this essay I will be exploring the themes of colonialism and assimilation and how it was represented throughout the 1955 Australian film Jedda, by Charles Chauvel; being the first Australian film that Aboriginal actors had taken on a protagonist role, even so far as to have the Aboriginal actors name appear first in the credits. The film is about a young Aboriginal girl, Jedda, who was orphaned as an infant and raised by the station owner’s wife, Sarah McMann. The woman was wanting to ‘civilise’ Jedda, teaching her to read and write in English, and how to play the piano instead of letting her learn the way of her tribal people by going on walkabout; finding bush tucker, and learning
Tim’s Vermeer Tim’s Vermeer is a documentary film. It is about the struggle of a man to recreate a painting of Vermeer by seeing a rebuilding of the studio of Vermeer through a mirror arrangement. Tim Jenison got the encouragement from David Hockney’s theory that painters used visual strategies to accomplish their fascinating quality and established a double-mirror version of the camera lucida. He spent approximately 130 days to create a perfect and flawless imitation of Vermeer’s music lesson. He finally reached to the conclusion that the double mirror technique is a practical clarification for the distinctively lifelike painting style of Vermeer (Howard).
When it comes to manipulation, it deals with deceitful influence especially for one 's own advantage. In the documentary film, Thin, Polly 's rebelliousness and persistent manipulation has led to her being removed from treatment. She was the “ring-leader” of the group. She gives Shelly mood stabilizers that were later on discovered in the room during a routine check by the staff. The mood stabilizers would give Shelly mood swings throughout the film.
The film called Smoke Signals, deals with the lifestyle of Native Americans living on an Indian reservation in Idaho. The main characters Victor and his best friend Thomas grew up together on this reservation. Thomas is a nerd who enjoys telling stories that have no interest to anyone. His parents died in an accidental fire in 1976, he was saved from the fire by Victors father Arnold Joseph. On the other hand Victor is a tough kid that never got over the fact that his father left his family when he was young.
Welcome to cinematic studies, accredited by the national top radio station, 666. I’m your host, Gurki Gill and todays show will be featuring an Australian director, Wayne Blair. Today we’ll be taking about an Australian iconic indigenous film, The Sapphires and its historical context. |What made the film feel like it was real?
The Bronze Screen introduced both positive and negative portrayals of Latinas and Latinos in film. While there are plenty of positive Latino roles in films, Latinos and Latinas should be included in more positive roles because the negative roles Latinos have in films cause negative stereotypes. Positive and negative representations of Latinos in films has always fluctuated throughout history, however the more negative ones seem to always overpower the good ones. The film, “The Bronze Screen”, gave many examples of the negative roles Latinos played in films throughout film history. Early films included Latino actors, however they did not always have a lead role or even a positive one.
Though they are friends, the lives of Pedro Machuca and Gonzalo Infante differ drastically in many aspects including family life, the luxuries they can afford, and the political affiliations chosen by their families. All of which relate to the common everyday life of Chilean citizens during the Allende Presidency, and the Pinochet Dictatorship implemented after the coup d'etat. During this time, the civil unrest never ceased, and life for chileans was generally either good or bad based on social status, income, and party affiliation. Both Machuca and Infante are classic examples of the division inequality of life amongst Chileans, with Machuca being a poor boy who lived in a shanty town, having very little education, and owning very few possessions. Where as Infante is wealthy, has a high end private education, and can afford to buy various luxury items such as brand name shoes and food for his family.
Individuality is unaccepted and isolated from our society that embraces conformed values. The Copy Shop and L’homme sans tete are examples of short films that reflect this ironic problem of society where individuals are not identified with their individual morals, but conformed morals enforced by society. The 2001 short film, Copy Shop by Virgil Widrich conveys the idea of conformity. This is done foremost through the metaphor of 'copies' that fill up the film's world that represent conformity, where the composer satirises our society which is filled up by 'copies' of individuals sharing conformed ideals.
The movie Smoke Signals, written by Sherman Alexie and Directed by Chris Eyre. Is a great movie about two characters who are very different. They both lose their fathers, live different lives on a reservation, and a very different outlook on life and emotions.
The Elimination: A Survivor of the Khmer Rouge Confronts His Past and the Commandant of the Killing Fields. Rithy Panh is an internationally and critically acclaimed Cambodian documentary film director and screenwriter. Rithy Panh was a young boy when Khmer Rouge revolutionaries arrived in Phnom Penh on April 17, 1975. Starting that day, he and his family were designated “new people”—the revolution’s code for those who needed “re-education”—and forcibly evacuated out of the city. That day began a terrifying experience that gradually took away most of his family, forcing Rithy to survive a series of brutal, and often arbitrarily cruel, ordeals.
More often than not, movies based upon novels are disappointing when the two are compared. Readers of James Dashner's The Scorch Trials are most likely appalled at how little the movie follows along with the book. The readers go in expecting to finally see the interpretation of the story they had previously experienced in their heads, only to be let down by how many of their favorite chapters were left out. The dripping metal ball scene, the "safe haven," and the lack of romance between Teresa and Thomas are just a few of the reader's favorite parts from Dashner's book that were cut from Wes Ball's movie adaptation. First, the dripping metal ball scene is left out entirely.
At some point of your life you meet very special people that carry very similar interests. This creates bonds that can be a very powerful and important part of your life. Some may say that bonds are created between a series of negative events that leads up to friendship. However, this is not true because in The Way, the main characters come together to walk the same path. Each character motivates each other to achieve the overall reason of why they wanted to walk The Camino De Santiago.
The tensions that emerge between the focus of a group and ordinary people both have claims of having more impact than the other. Even though the globe has evolved it 's about the divide between the ones who grow with advances and the ones who are left behind. Social theorist look into the everyday realities of the world through perspectives on society. Each person’s gender, society class, and nationality are encountered with a particular context or junction where several social categories intercept, called intersexuality. One cannot gain knowledge just but looking at a single thing, like only social class.
Don’t let the movie title, Milk, fool you. The movie’s title has nothing to do with the milk beverage. Sorry milk enthusiast. On the other hand, for those who love politics then this is the movie for you. This movie is solely focused on American Democracy.
