Evaluation of perovskite solar cell material by sample observation TG-MS

TA-2024: Evaluation of perovskite solar cell material by sample observation TG-MS

 

Introduction

The high power generation efficiency and the potential for low-cost processes of Perovskite solar cells have been actively researched and developed in recent years. In this application, the thermal behavior of lead methylammonium iodide (MAPbI₃, (CH₃NH₃)PbI₃), a representative perovskite crystal intensifying agent, was investigated by sample observation TG-MS.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).

 

 

DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.

 

The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.

 

TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
