Hybrid materials for photovoltaics

The combination of nanocrystals and conjugated polymers is attractive for photovoltaics because they absorb sunlight in a complementary way. However, very few results, generally non-reproducible, followed the first promises of 2002.

A team at our laboratory in collaboration with INES obtained a series of cells with a satisfactory yield of 1% on average on 10 samples. These cells are moreover 10 times larger than those of the literature. This progress was made by working on a new solvent and on the implementation of the hybrid film.
