Embodiment 1
[0044] A method for preparing rollable nano-paper-based flexible solar cells by 3D aerogel jet printing includes the following steps and process conditions:
[0045] A) Preparation of flexible paper-based nano-optical paper: the whole cellulose base paper is directly soaked with ionic liquid, and the nano-optical paper substrate is regenerated by hot rolling, including the following steps:
[0046] 1) Use ionic liquid (N-ethylimidazole hydrogen phosphite) to soak the whole cellulose paper (double-circle medium-speed qualitative filter paper) for 10 seconds, and then sandwich it between the polytetrafluoroethylene film. Use a plate vulcanizer at 80℃ Press 1MPa and heat for 120 seconds to partially dissolve the surface of the whole cellulose paper and fill the pores to ensure that the light refractive index in the thickness direction is almost the same to prepare partially dissolved whole cellulose paper.
[0047] 2) The partially dissolved whole cellulose paper is soaked in absolute e...

[0060] A method for preparing rollable nano-paper-based flexible solar cells by 3D aerogel jetting precision printing includes the following steps and process conditions:
[0061] A) Preparation of flexible paper-based nano-optical paper: the whole cellulose base paper is directly soaked with ionic liquid, and the nano-optical paper substrate is regenerated by hot rolling, including the following steps:
[0062] 1) Use ionic liquid (N-ethylimidazole hydrogen phosphite) to soak the whole cellulose paper (double-circle medium-speed qualitative filter paper) for 10 seconds, and then sandwich it between the polytetrafluoroethylene film. Use a plate vulcanizer at 80℃ Press 1MPa and heat for 30 seconds to partially dissolve the surface of the whole cellulose paper and fill the pores to ensure that the light refractive index in the thickness direction is almost the same to prepare a partially dissolved whole cellulose paper.

[0073] A method for preparing rollable nano-paper-based flexible solar cells by 3D aerogel jetting precision printing includes the following steps and process conditions:
[0074] A) Preparation of flexible paper-based nano-optical paper: the whole cellulose base paper is directly soaked with ionic liquid, and the nano-optical paper substrate is regenerated by hot rolling, including the following steps:
[0075] 1) Use ionic liquid (N-ethylimidazole hydrogen phosphite) to soak the whole cellulose paper (double-circle medium-speed qualitative filter paper) for 10 seconds, and then sandwich it between the polytetrafluoroethylene film. Use a plate vulcanizer at 80℃ Press 1MPa and heat for 30 seconds to partially dissolve the surface of the whole cellulose paper and fill the pores to ensure that the light refractive index in the thickness direction is almost the same to prepare a partially dissolved whole cellulose paper.
