Solar Energy is currently not effective due to a solar cell’s excitation of one electron per photon of light. Quantum dots are semiconducting nanocrystals that have multiple exciton generation, allowing multiple electrons to be excited per photon of light. However, CdSe quantum dots contain cadmium, a harmful substance to the environment. The purpose of this project was to find a replacement for CdSe commercial quantum dots. The hypothesis is if CuInS2 and CuInSe2 quantum dots are applied to the solar cell, then there will be a significant increase in power from the control. The sub-hypothesis is if the CuInS2/Se2 quantum dots at 45 minutes are applied to the solar cell, then there will be a significant increase in power. The engineering goal was to optimize solar cell power while creating a cost-effective and sustainable quantum dot. CuInS2/Se2 quantum dots were heated in separate beakers for 15, 30, and 45 minutes, and were then applied to the solar cells for testing. CdSe 610 nm quantum dots were also applied to solar cells as a comparison. CuInS2 and CuInSe2 solar cells had a statistically significant increase in power from both the control and 610nm. The CuInS2/Se2 solar cells proved to be a cheaper replacement of CdSe quantum dots, costing $265.42 and $287.07, respectively; the CdSe quantum dots cost $845.00 to produce. There proved to be a steady increase in power in CuInS2 solar cells across 15, 30, and 45 minutes. These cadmium free quantum dots showed significant improvement from the average solar cell, at one point showing a 52.61% increase from the control in CuInSe2 solar cells at 45 minutes.
