More Information
Summary:The invention relates to a tandem photovoltaic device comprising: a sub-cell A based on perovskite, and a sub-cell B with a silicon heterojunction, the sub-cell A successively containing: a hole transport layer HTL which is a double layer consisting of a neutral layer HTL-N based on PEDOT:PSS and an acid layer HTL-A based on PEDOT:PSS, the PEDOT being poly(3,4-ethylenedioxythiophene) and the PSS being poly(4-styrenesulfonate), an active layer based on perovskite, and an electron transport layer ETLA, the HTL-A layer being in direct contact with the active layer based on perovskite.
