Automated Solar-Powered Chicken Coop Door, Brenna Yagade
Computer Engineering
The purpose of this project was to plan, design, and build an automated, low power system to open and close a chicken-coop door, which is powered through a solar panel.
Minimizing Sheet Resistance Of Organic Photovoltaic Cell Top Contact Electrode Layer: Silver Nanowire Concentration Vs. Conductive Polymer Doping Concentration, Caitlyn Cook
Materials Engineering
The top contact electrode layers of nine organic photovoltaic cells were prepared with two varying factors: three Silver nanowire (AgNW) densities deposited on a conductive polymer doped with three concentrations. Silver’s low sheet resistance of 20-Ω/sq is hypothesized to lower the sheet resistance of the anode layer and thus enhance the overall efficiency of the cell. Four-point probe measurements indicated that increasing AgNW density in the top contact electrode layer of an organic photovoltaic cell significantly reduces sheet resistance from 52.2k-Ω/sq to 18.0 Ω/sq. Although an increase in doping concentration of the conductive polymer reduced sheet resistance in low AgNW …

Solar Decathlon Instrumentation And Controls, Timothy Ambrose, Mateo Begue, Andrew Elliott
Mechanical Engineering
The Instrumentation and Controls team has designed a control and instrumentation system for the 2015 Cal Poly Solar Decathlon house that will monitor temperature, humidity, and energy usage throughout the house and control the phase change material duct. It will relay information to the user through a tablet application developed by the Computer Science team. The team has also designed a lighting control scheme for use with Lutron’s HomeWorks QS lighting control system.
Smart Solar Oven, Aaron Gragg
Smart Solar Oven, Aaron Gragg
Computer Engineering
Though solar oven technology provides a green and cost effective means of cooking, it is often not adopted because it fails to meet the demands of speed and reliability that are commonplace in our society. This project explores the modification of a traditional box solar to meet these demands by allowing the oven to report temperature to a user’s phone as well as orient itself towards the sun throughout the day.
