Background of the Study
The aftermath of typhoon Yolanda or internationally known as typhoon Haiyan, is one of the worst typhoons Philippines have experienced. This calamity resulted to destruction of properties and this calamity has also caused blackouts all over the place. Electricity— is badly needed after a typhoon, especially after the typhoon Yolanda. Electricity is used to charge cellphones to communicate and get some help. It is also used to power radios and televisions to be updated for current news and further instructions from the government. But because of absence of electricity, communications and media are not likely to serve their purpose.
Energy comes in different forms. Light, heat, and electricity are forms of energy. Heat energy is used in solar panels in order for it to generate electricity.
A solar panel is composed of arrays of solar cells. The solar cells are responsible for trapping and converting the sunlight into electricity. This is possible because of the photovoltaic effect. Manganese (Mn) is a hard, brittle, silvery metal used to harden steel. It is used to form many important alloys. Manganese (IV) oxide is used as depolarizer in dry cells, and to decolorize glass. Manganese (II) oxide is a powerful oxidizing agent and is used in quantitative analysis. Manganese minerals are widely distributed with pyrolusite and rhodocrosite being the most common.

Significance of the Study
Electricity is now widely used in the community Huge power plants provide electricity to the distributors in which they distribute to every home in the community. But the price of electricity is increasing steadily nowadays, leaving the community a hard time to cope up with their daily expenses. Typhon Yolanda or internationally known as Typhoon Haiyan has left Philippines especially the families in Tacloban in great destruction. This typhoon also caused black-outs to every affected community. Due to lack of electricity, communications and media are likely impossible to serve their purposes. Nuclear energy is used by some company to generate electricity but nuclear energy has posed grave threats to the community and its health.
Hydro-electric energy is likewise used to generate electricity but due to current issues of drought it results to power shortage. Wind energy is also used in some places the wind is constant but not all places has strong winds to generate electricity. The sun, which is the abundant source of life on Earth, also generates solar energy. Solar energy is being converted to electricity for the community to use. In which the solar energy is a renewable source of energy. This study can help the community by using the solar energy in order to obtain electricity. This study can help those persons who are in need of electricity especially those who are affected by the Typhoon Yolanda as this research study contains information about the effect of manganese as alternative for silicon as the main-component of solar cells.
Independent Variables Dependent variables Manganese solar cell Mean electricity production in volts Silicon solar cell Mean capability of durability Mean market acceptability rating Figure 1: the effect of manganese and silicon solar cells to the mean electricity production in volts, mean capability of durability, and mean market acceptability rating.
Scope and Limitations
This study will be able to generate stable production of electricity in form of volts (V) from a solar cell with manganese as its main component. Silicon will be substituted by manganese as the main component of a solar cell because of its properties similar to silicon. With these properties, manganese can also conduct and absorb heat similar to the silicon but in a much cheaper price. The solar panel should be able to generate electricity enough for regular household use of 220 volts. The materials that will be used should be in good condition to be able to achieve the expected results.
The mean electricity production in volts, mean capability of durability, and mean market acceptability rating will be computed with the given formulas. This study will be constructed and completed at Blk. 28, Lot 61, Pahanocoy Village, Bacolod City. The main component, manganese will be acquired at Kabankalan City, where the supply is abundant. This study will be limited in testing the production of electricity in form of volts (V), generated by the manganese solar cell. In which the input should be 12 volts (V) and the output, 220 volts which is enough to supply electricity for household use.

Today, most manganese is still obtained from pyrolusite, although it is usually burned in a furnace with powdered aluminum or is treated with sulfuric acid (H2SO4) to form manganese sulfate (MnSO4), which is then electrolyzed. Almost 90% of manganese produced each year plays a great role in the production of steel. Manganese is added to molten steel to remove oxygen and sulfur and is alloyed with steel to make it easier to form and work with and to increase steel’s strength and resistance to impact. One of these examples is the railroad tracks, which are made with steel that contains as much as 1.2% manganese.
Manganese is also used to give glass an amethyst color and is responsible for the color of amethyst gemstones. Manganese dioxide (MnO2), the most common compound of manganese, makes up about 0.14% of the Earth’s crust. It is used in dry cell batteries to prevent the formation of hydrogen, to remove the green color in glass that is caused by the presence of iron contaminants, and as a drying agent in black paints. http://education.jlab.org/itselemental/ele025.html Silicon
Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth’s crust. Today, silicon is produced by heating sand (SiO2) with carbon to temperatures approaching 2200°C. When silicon is doped with other elements, it is used to manufacture solid-state electronic devices, such as transistors, solar cells, rectifiers and microchips. Silicon dioxide (SiO2), silicon’s most common compound, is the most abundant compound in the earth’s crust.
It commonly takes the form of ordinary sand, and also exists in some kind of rocks. Silicon dioxide is extensively used in the manufacture of glass and bricks. Silicon forms other useful compounds. It is widely used as abrasives, adhesives, and preservatives. Silicon is also an important ingredient in silicone, a class of material that is used for such things as lubricants, polishing agents, electrical insulators and medical implants. http://education.jlab.org/itselemental/ele014.html Local Literature

As of today, solar energy has been viewed as only a minor contributor in the energy mixture of the US due to cost and intermittency constraints. But, solar energy proved that it is this cost competitive with fossil fuel energy generation. It shows that with the right incentives, cost competitiveness with grid prices in the US can be attained by 2020. Based on expected improvements of established, commercially available PV, CSP, and CAES technologies, they show that solar energy has the technical, geographical, and economic potential to supply 69% of the total electricity needs and 35% of the total (electricity and fuel) energy needs of the US by 2050. If they extend the scenario to 2100, solar energy supplies over 90%, and together with other renewables, 100% of the total US energy demand with a corresponding 92% reduction in energy-related carbon dioxide emissions compared to the 2005 levels. http://www.sciencedirect.com/science/article/pii/S0301421508004072 Local Study
