How does sunlight affect photovoltaic performance?

Prolonged exposure to sunlight causes photovoltaics'' performance to degrade in the neighborhood of a percent or two per year, and more rapidly when exposed to particle radiation from solar flares. In addition to generating electrical power, solar arrays have also been used to generate atmospheric drag for aerobraking operations.
