Dye-sensitized solar cells are considered one of the most promising advancements in alternative energy. They are cheap, easy to make, and considerably efficient. Efficiencies are the key area of interest in our research, and we worked with the formula and creation of the Titanium Dioxide paste as the key method. Another area that we started looking at was quantum dots as they have the theoretical potential to reach efficiencies much higher than we could hope for from just organic dyes. Also, another way to test the pastes was created in the making of an Electrochemical Impedance Spectrometer. This instrument is capable of reading the resistance and capacitance of the solar cell itself and from this, it can help us better determine how well our pastes are working.
