Dream Come true

This is the moment God answered my prayer. I couldn't imagine that we won  in the National Science Fair in the Physical Science, Team Category the fact there were 15 entries compete from the different regions in the Philippine. We got the third Place in the contest. But you know before we garnered this place a lot of trials we have experienced specially when it comes to financial constraints from the start of the contest in the Division, Regional and even in the National Level. From the start of the investigation of the project, for choosing of our consultant, entering in the institution where we conducted our project. The materials that we are going to be used and the cost of each materials. Another factor is my background in physics the fact that this is the first time to have a physical science project because my major in Biology. All of this constraints made me strong and even my researcher to continue the project. Thank you Lord for the opportunity and blessings to us specially to the Researchers Jahaziel Mark Bahan, Jissah Mae Bahan, Wilyneth Cantong, and to the Party Roithes Perez, Christine Unabia and Emerald Logronio for the job well done. To our consultant Dr. Rey Vequizo and Mayvel Odarve thank you so much for your expertise and skills rendered to us to make the project successful. I have learned a lot from you. I salute to both of you! to the faculty and staff of Trento National High School headed by our School Principal Mr. Leopoldo Pulido, my warmest gratitude to you all, to the parents of my researcher, III-SSC who help us raised money through caroling for our Travels, PTCA  headed by PTA President Jovenial Cabusog, To our Governor Adolph Edward Plaza, to Deped Family headed by Madam Crucita Zm. Taala, to Dr. Erlinda Atienza,  Sir Abraham Masendo, Thank you also for the encouragement to continue my endeavor.To all who helped us financially Thank you so much. I know God is always there for us. In this connection I am knocking the hearts of any company that will help to give funds for our project so that we can make a solar panel out of our improvised solar cell rest assured that our solar panel is feasible and it is very helpful to minimize the problem in our country in global warming. I am looking forward for a positive response of the people who can read my blog. Thank you and More Power! God Bless and Merry Christmas and Prosperous New Year.

Abstract

The quest to find environmentally clean, sustainable, and renewable energy source have been an agenda of human race. Among the unconventional energy sources; solar energy has appeared to be the most practical alternative to conventional fossil-fuel based energy sources. This study aims to determine the capability of anthocyanin in the red cabbage to convert light into electricity by fabricating anthocyanin-sensitized solar cells.

Anthocyanin extracted from the crude extract of red cabbage underwent transmittance and absorbance analysis using the UV-Vis Spectroscopy analysis to determine its light absorbing capability. Anthocaynin-sensitized solar cells are then fabricated with ZnO/Anthocaynin/Electrolyte configuration. Exposure to stray light from the fluorescent light and halogen lamp (560 nm, 100W) was carried out to elucidate and measure the electricity generated by the sensitized solar cell.

Pythochemical analysis of the extract verified the presence of anthocyanin. A high absorption band in the wavelength range of 450-540 nm indicates the capability of anthocyanin to absorb light. The presence of electrolyte enhances the reactivity towards light as observed in the increase by the absorption of the samples.

The current generated by the sensitized solar cell is mainly attributed to the presence of anthocyanin in the cell where the current generated with the two light sources is comparable. Although the Anthocyanin-sensitized solar cell generated current is low, the trend of its current-voltage properties is the same with a standard Si-based Solar cell. The Ability of the Anthocyanin-sensitized solar cell to generate current at the same range, with and without the presence of an intense light source, is also a promising property for a good solar cell device.
