Pb-free glass frits prepared by spray pyrolysis as inorganic binders of Al electrodes in Si solar cells

Effect of the Molar Ratio of B2O3 to Bi2O3 in Al Paste with Bi2O3–B2O3–ZnO Glass on Screen Printed Contact Formation and Si Solar Cell Performance

“…[14][15][16] However, the solar cell industry has recently been moving towards environment-friendly materials, especially Pb-free Al pastes. 7,17) It was known that since both PbO 2þ and Bi 3þ showed similarities that are iso-electronic and highly polarizable, Bi 2 O 3 could replace PbO for the Pb-free glass composition. 18) High Bi 2 O 3 -contained glass dose not occurred the devitrification when it is cooling and has relatively low T g .…”

Characteristics of CAS and Bi-Based Glass Frit as the Inorganic Binder of Alumina Insulation Slurry

“…Scientists have made a lot of research on glass frits as inorganic binder. Pb-free glass frits were prepared by spray pyrolysis and investigated as inorganic binder for Al electrode backside contacts in Si solar cells [2]. Bi 2 O 3 -ZnO-SiO 2 -B 2 O 3 -Al 2 O 3 -CaO glass frit with spherical shape and submicron size as an inorganic binder for silver conducting film are investigated by Jung Hyun Kim and Hye Young Koo [3].…”

Desenvolvimento e caracterização de módulos solares de células de TiO2/corante com eletrólito gel

“…Para evitar que a frita entre em contato com o contra eletrodo neste trabalho foi utilizado uma distância de separação entre os eletrodos de 25 µm, superior à altura desta camada isolante, permitindo também que a frita fosse utilizada apenas para isolar a prata. Materiais vítreos livres de chumbo (leadfree) tem sido utilizados para melhorar o desempenho de módulos [78] [79] [96] , quando utilizados para a selagem [97] .…”
