- Аннотация: Present developments in organic photoelectronics are aimed to increase of the efficiency of converting solar energy into electricity by creating new chemical compounds and optimizing the composition of known materials. Organometallic compounds forming perovskite structure (halides of methyl ammonium or formamidium of lead or tin) have shown to be promising photoconductors for photovoltaic solar cells (SC). Charge transport layers that improve the collection of electrons and holes at the corresponding electrodes play an important role in the SC devices. Here, a comparative study of SCs with a photoactive layer made of lead methyl ammonium iodide of perovskite structure and a hole transport layer (HTL) based on a polyaniline complex with polymeric acid was carried out. HTL was deposited on the substrate using various methods: drop casting, electrochemical deposition, 2D inkjet printing. The conditions for successful deposition of the HTL layer by inkjet printing, resulting in the device with efficiency exceeding 12%, were found. The method allows forming a layer of uniform thickness over the entire area of a SC sample providing a high reproducibility of the parameters of individual pixels. The effect of the perovskite layer thickness in the range of 350–500 nm on the SC efficiency was found to be negligible. This is in a good agreement with the weak dependence of the exciton generation rate in the photoactive layer on its thickness resulted from modeling the optical parameters of a polymer semiconductor in the framework of the Maxwell-Garnet model.
