PHOTOVOLTAIC CELLS AND METHODS FOR PRODUCTION THEREOF

摘要

A photovoltaic device comprising a light trapping and light diluting structure has a first reflective surface portion (4a), at least partially provided with a first active material portion (3a), and a second reflective surface portion (4b), at least partially provided with a second active material portion (3b). At least one of the first and second active material portions (3a, 3b) is a printed photovoltaic active material. The reflective surface portions (4a, 4b) make an angle (a) of less than or equal to 90 degrees relative to each other, such that light reflected from one of the reflective surface portions (4a, 4b) is directed to the other one of the reflective surface portions (4b, 4a). Methods for producing such structures are also disclosed.
