  1. Evaluation of the Electrical Characteristics of Thin-Film Solar Cells atUnited Solar OvonicsTroy, Michigan Carolyn Hartzell September 24, 2010

  2. Thin-Film solar cells • Adhesive mounting and flexibility great for applications House in Germany QinetQ Zephyr

  3. Triple Junction Solar Cell • Three different cells combined in series – layered • Performance variables: Pmax, Isc, Voc, FF, Rs, Efficiency • Efficiency: • Can calculate from power output and area • More informatively, can calculate each individual cell, and combine

  4. Spire Project: • Solar simulator • Problem: spectrum mismatch • Solution: blue filter • Other tasks: optimize, determine calibration procedure

  5. Outdoor Modules Project:

  6. Outdoor Modules Data Analysis:
