Thin-film organic solar cells offer an inexpensive and environmentally friendly alternative to semiconductor solar cells. Despite potentially high quantum efficiency, thin-film cells have low light-absorption compared to semiconductor variants. To increase absorption we deposited gold nano-particles onto the thin-film substrates, increasing the surface area for light harvesting molecules. Photocurrent measurements taken with a lock-in amplifier increased by approximately 50% with addition of the nano-particles. Such improvements could make photovoltaics more cost competitive with fossil fuels and help mitigate climate change.
