Cu(In,Ga)Se2 based ultrathin solar cells the pathway from lab rigid to large sc...
Lopes, T. S.; Teixeira, J. P.; Curado, M. A.; Ferreira, B. R.; Oliveira, A. J. N.; Cunha, J. M. V.; Monteiro, M.; Violas, A.; Barbosa, J. R. S.The incorporation of interface passivation structures in ultrathin Cu(In,Ga)Se2 based solar cells is shown. The fabrication used an industry scalable lithography technique—nanoimprint lithography (NIL)—for a 15 × 15 cm2 dielectric layer patterning. Devices with a NIL nanopatterned dielectric layer are benchmarked against electron-beam lithography (EBL) patterning, using rigid substrates. The NIL patterned devic...

Rear optical reflection and passivation using a nanopatterned metal/dielectric ...
Lopes, T. S.; Cunha, J. M. V.; Bose, S.; Barbosa, J. R. S.; Borme, J.; Donzel-Gargand, O.; Rocha, C.; Silva, R.; Hultqvist, A.; Chen, W.-C.Currently, one of the main limitations in ultrathin Cu(In,Ga)Se2 (CIGS) solar cells are the optical losses, since the absorber layer is thinner than the light optical path. Hence, light management, including rear optical reflection and light trapping is needed. In this work we focus on increasing the rear optical reflection. For this, a novel structure based on having a metal interlayer in between the Mo rear c...
