2.627 Fundamentals of Photovoltaics (Fall 2011, MIT OCW): Lecture 16

2.627 Fundamentals of Photovoltaics

2.627 Fundamentals of Photovoltaics (Fall 2011, MIT OCW). Instructor: Prof. Tonio Buonassisi. In this course, students learn about the fundamentals of photoelectric conversion: charge excitation, conduction, separation, and collection. Lectures cover commercial and emerging photovoltaic technologies and cross-cutting themes, including conversion efficiencies, loss mechanisms, characterization, manufacturing, systems, reliability, life-cycle analysis, and risk analysis. Some of the course will also be devoted to discussing photovoltaic technology evolution in the context of markets, policies, society, and environment. (from ocw.mit.edu)

Lecture 16 - Solar Cell Characterization

Classification, function, and deliverables of solar cell characterization. Jsc loss measurements: optical reflection, spectral response, minority character diffusion length. FF & Voc loss measurements: IV curves, series resistance (contact & sheet) , shunt resistance (lock-in thermography), electroluminescence.
