FORMATION OF SOLAR CELLS ON FOIL SUBSTRATES

摘要

The present invention relates to fabrication of photovoltaic devices and more specifically to processing and annealing of absorber layers for photovoltaic devices. Embodiments of the present invention allow fabrication of CIGS absorber layers on aluminum foil substrates. For example, a photovoltaic device includes an aluminum foil substrate (102), an optional base electrode (104) and a nascent absorber (106) including material containing elements of groups IB, IIIA, and (optionally) VIA.
