Spray on Solar Panels using CIGS nanocrystals
Photovoltaic devices (PVs) were fabricated by spray-coating an ink of copper indium diselenide (CIS) nanocrystals as the light-absorbing layer. Without high-temperature post-deposition annealing, PVs were made on glass and plastic substrates with power conversion efficiencies of up to 1.9% and 1.1% IEEE Spectrum covers this work and indicates if it works with 10% efficient, Korgel …
