• Thin-Film solar cells• Adhesive mounting and
flexibility great for applicationsHouse in Germany
QinetQ Zephyr
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
Spire Project:
• Solar simulator– Problem: spectrum
mismatch– Solution: blue filter– Other tasks:
optimize, determine calibration procedure
