A case study on monitoring Potential Induced Degradation (PID) recovery in multi-crystalline modules

Kwembur, Isaac M.; McCleland, J. L. C.; Vorster, F. J.; van Dyk, E. E. (2020)

Potential Induced Degradation (PID) causes significant module degradation leading to decreased power output in photovoltaic (PV) power plants. Many PV power plants are constructed using transformerless inverters and may ...
Detection of potential induced degradation in mono and multi-crystalline silicon photovoltaic modules

Kwembur, Isaac M.; McCleland, J. L. C.; van Dyk, E. E.; Vorster, F. J. (Elsevier, 2020-03)

Potential induced degradation (PID) is a performance limiting defect that profoundly impacts the power output of Photovoltaic (PV) modules. PID occurs because of leakage current between the solar cells and the aluminium ...
An easily fabricated low-cost potentiostat coupled with userfriendly software for introducing students to electrochemical reactions and electroanalytical techniques

Li, Yuguang C.; Melenbrink, Elizabeth L.; Cordonier, Guy J.; Boggs, Christopher; Khan, Anupama; Kwembur, Isaac M.; Nkhonjera, Lameck K.; Bahati, David; Billinge, Simon J.; Haile, Sossina M.; Kreuter, Rodney A.; Crable, Robert M.; Mallouk, Thomas E. (American Chemical Society and Division of Chemical Education, Inc., 2018-07)

This paper presents a teaching kit that combines the fabrication of a low-cost microcontroller-based potentiostat and a LabVIEW-generated graphical user interface. The potentiostat enables undergraduate-level students to ...
Monitoring the natural recovery of potential induced degradation in poly-crystalline photovoltaic modules

Kwembur, Isaac M.; Crozier McCleland, J. L.; van Dyk, E. E.; Vorster, F. J. (2022-02)

Potential induced degradation (PID) is a defect that has a severe effect on the performance of photovoltaic (PV) modules in field conditions. It is caused by leakage currents and the accumulation of sodium ions (Na+) between ...
Thermal emittance and solar absorptance of cds thin films

Mosiori, Cliff; Kwembur, Isaac M.; Maera, John (2016-08)

CdS thin films were grown on highly cleaned substrates of Microscope glass slides using solution deposition technique at different molar concentrations at constant time and repeated at a fixed molar concentration at for ...
