Solar Cell Potential Induced Degradation Sensor, Luc Alexandre Tousignant
Materials Engineering
It is important to maintain Photovoltaic (PV) cells and protect them from damage mechanisms like Potential Induced Degradation (PID), which can contribute to shorter lifespans and lower efficiencies. Current leakage through cell encapsulation can cause charge migration in PV cells that reduces the maximum quantum efficiency, which is the cause of PID. An experiment was setup to determine the feasibility of a non-silicon sensor able to produce similar leakage behavior to traditional PV cells under recorded humidity conditions. Thin sheet metals were encapsulated in EVA, a common PV encapsulant polymer, and mounted in aluminum framing. Three sensors, along with a …

The Analysis And Study Of Power System Designs For Same Polytechnic College In Tanzania, Kevin Lum Hua
Master's Theses
The Mbesese Initiative for Sustainable Development (MISD) is a group aiming to help eliminate extreme poverty in Africa by creating educational opportunity. One project that the group is currently doing is to build Same Polytechnic College (SPC) in Tanzania. As part of the project, this thesis aims to study and analyze the electrical power system and distribution for the college. Based on the projected load profile of the college and high potential for solar generation in Tanzania, several different power systems utilizing local utility AC electricity and/or photovoltaic (PV) DC electricity are explored and simulated for their feasibility and performance. …

Construction Management
The National Electrical Contractors Association (NECA) student chapter at California Polytechnic State University in San Luis Obispo, California was selected by an association called ELECTRI International to participate in their Student Community Service Initiative program. The goal of the program is to “Encourage construction management and electrical engineering students to take an active role in improving access to electricity in developing communities” (“Student Passport Program”). This paper summarizes the findings of a student-led project made possible by ELECTRI International’s program. The project included coordinating, funding, and executing a project to facilitate the installation of photovoltaic water pump systems to indigenous …
