摘要
There is disclosed a method of preparing a photovoltaic device. In particular, the method comprises making thin-film GaAs solar cells integrated with low-cost, thermoformed, lightweight and wide acceptance angle mini-CPCs. The fabrication combines ND-ELO thin film cells that are cold-welded to a foil substrate, and subsequently attached to the CPCs in an adhesive-free transfer printing process. There is also disclosed an improved photovoltaic device made by the disclosed method. The improved photovoltaic device comprises a thin-film solar integrated with non-tracking mini-compound parabolic concentrators, wherein the plastic compound parabolic concentrator comprise two parabolas tilted at an angle equal to the acceptance angle of the compound parabolic concentrator.
