">18% efficient in structure-inverted solar cells with 1cm2 area... 24,700 hour (predicting 16 year) lifespan... structure-inverted, or n-i-p solar cells, are more stable... zinc oxide bottom contact creates narrow recombination area leading to photocurrent loss... overcome applying thin, solvent-processed silicon oxide nitrate passivation layer on bottom contact, eliminating recombination area, improving efficiency... potential for using the method in the large-scale production of efficient and stable organic solar cells"
