Abstract

A PRESENTE DIVULGAÇÃO REFERE-SE A UM PROCESSO PARA A IMOBILIZAÇÃO DE COMPOSTOS DE CHUMBO SOLÚVEIS EM CÉLULAS SOLARES DE PEROVSKITA NO CASO DE QUEBRA DA CÉLULA OU DE INCÊNDIO, INTRODUZINDO ADITIVOS NAS CÉLULAS. OS REFERIDOS ADITIVOS NA PRESENÇA DE ÁGUA INTERAGEM COM COMPONENTES À BASE DE CHUMBO PRESENTES NA CÉLULA DE PEROVSKITA ATRAVÉS DE UMA REAÇÃO DE PERMUTA IÓNICA, FORMANDO COMPOSTOS MENOS SOLÚVEIS E COM ESTABILIDADE TÉRMICA SUPERIOR. OS COMPOSTOS DE CHUMBO MENOS SOLÚVEIS FORMADOS NO MÉTODO DIVULGADO REDUZEM EM DUAS ORDENS DE GRANDEZA A LIBERTAÇÃO DE IÕES DE CHUMBO DA CÉLULA DE PEROVSKITA EM CASO DE DERRAME. UM OUTRO ASPETO DA DIVULGAÇÃO É DESCRITO COMO UM ADITIVO NA CÉLULA DE PEROVSKITA DE UM ABSORVEDOR DE ÁGUA FEITO DE POLÍMERO HIDROFÍLICO; ABSORVE A ÁGUA, EXPANDE-SE DENTRO DA CÉLULA BLOQUEANDO O PERCURSO DA ÁGUA ATRAVÉS DE FISSURAS NA CÉLULA. A LIBERTAÇÃO DE CHUMBO DA CÉLULA SOLAR DE PEROVSKITA COM OS ADITIVOS DIVULGADOS FOI REDUZIDA EM QUATRO ORDENS DE GRANDEZA EM COMPARAÇÃO COM UMA CÉLULA SEM OS REFERIDOS ADITIVOS.This disclosure refers to a process for immobilizing soluble lead compounds in perovskite solar cells in the event of cell breakage or fire, by introducing additives into the cells. These additives, in the presence of water, interact with lead-based components present in the perovskite cell through an ion exchange reaction, forming less soluble compounds with superior thermal stability. The less soluble lead compounds formed in the disclosed method reduce the release of lead ions from the perovskite cell by two orders of magnitude in case of spillage. Another aspect of the disclosure is described as an additive in the perovskite cell of a water absorber made of hydrophilic polymer; it absorbs water, expands within the cell, blocking the path of water through fissures in the cell. The release of lead from the perovskite solar cell with the disclosed additives was reduced by four orders of magnitude compared to a cell without said additives.
