CH3NH3PBI3 IV Output Parameters Degradation Investigation

Abstract

Organic photovoltaics, based on hybrid inorganic organic optoelectronic perovskites, with structure alkali-metal-halide are the newest emerging technology in the third generation development. Despite tremendous efficiency records, more than 21 %, optoelectronic perovskites' instability prevents their commercialization and mass production. Issues with degradation are caused by various types of environmental influences. The main issues with stability and power loss in devices are linked to moisture, oxygen, temperature, and light-induced structure defects. Initial measurements are taken after long term debugging with minimal aggressive exposure to environmental conditions. In this case, preliminary degradation studies begin from measurements of light-induced effects. In this work, we will present the main trends in degradation of external characteristics during common I-V measurements, in the order of parameters which were effected the least by environmental factors. This investigation was made on fixed CH3NH3PBI3 solar cells with standard 1.5 AM testing and initial efficiencies more than 8 %.

Creation of a Tunable Diode Based on Nanotubes with an Ion Gate

“…For standard inorganic diodes, the rectification coefficient reaches values from 10 3 to 10 8 . Inorganic diodes, devices with doped areas, are low-impedance devices having basic charge carriers with initial concentrations of the order of 10 16 -10 20 cm 3 .…”

“…In turn, an organic asymmetric diode is characterized by the fact that an organic semiconductor, for example, a poly-conjugated polymer, poly-3-hexyl thiophene, is placed between two electrode plates, indium tin oxide and aluminum respectively [1][2][3][4][5].…”

Solar Cell Manufacturing Method with the Structure of the Bulk Heterojunction Based on Organic Semiconductors with a Direct Architecture

“…The process of laboratory testing consistent: cleaning and plasma treatment of substrates with transparent conductive layer by spin coating [7][8], sputtering cathode polymeric structure of the solar cell and the subsequent annealing at 130-150 ° C. In view of this it is necessary to fix the deviation of the electrical characteristics. Directly the main attention linked to the indicator, energy conversion efficiency, short-circuit current density J sc , and the open circuit voltage U xx .…”
