[20a-PB2-18] Fabrication of metal electorodes by using heat press equipment on a thin film perovskite solar cell
Keywords:perovskite solar cell, plastic film, heat press
Lead-halide perovskite solar cells are observed to have an energy conversion efficiency comparable
to that of conventional Si solar cells. As the perovskite solar cells can be prepared by simple solution
processes and hence, they have clear advantage over the conventional Si solar cells. It is expected
that the perovskite solar cells can be produced by roll-to-roll printing processes. A roll-to-roll
printing process can employ a flexible plastic substrate, which does not have a high heat resistivity.
Using such a flexible substrate will lead to produce a very thin-film type solar cells. However, the
fabrication of the metal electrodes on such thin film type solar cells will be a challenge.
Here, we have prepared a film type perovskite solar cells by using a polyethylene naphthalate (PEN)
film and we attempted to fabricate the metal electrodes by attaching water-proof barrier film with
deposited patterned Au patterns with a thickness of 50 nm. The films are placed in the following
order and thereafter, the films are heat laminated. First, the water-proof barrier film with Au, second
perovskite solar cell, and then, heat seal film water proof barrier film. The positive and negative
electrodes of the perovskite solar cells were contacted on the Au pattern with the water-proof barrier
film in face-to-face configuration.
After the completion of the fabrication, we measured the current-voltage characteristics of this
sealing solar cell, and verified the distribution of the photocurrent in the solar cells to assess the
electrode contact between a solar cell and Au on barrier film.
