Introduction to Perovskite Solar Cells in an Undergraduate Laboratory Exercise

Abstract [en]

The course Functional Materials at Karlstad University aims for undergraduates to study some of the functional materials of the 21st century. One of the hottest topics in photovoltaic research is hybrid organic-inorganic perovskite solar cells due to their easy methods of fabrication, cheap costs and potential for high power conversion efficiencies. A laboratory manual is compiled for the course, in which students are encouraged to build perovskite solar cells with a device architecture of FTO/TiO2/MAPbI3/CuSCN/Carbon/FTO using spin coating and annealing for testing in a solar simulator. The power conversion efficiency achieved with this method reaches 0.056 %, with suggestions for improvement when done by students. Absorption properties are examined using UV-vis spectroscopy and the band gap energy of MAPbI3 is established as 1.59 eV. By using these techniques, students will earn a greater understanding for one of the most relevant topics of photovoltaic research and different equipment used in its fabrication and characterization.

Abstract [sv]

Kursen Funktionella material på Karlstads universitet har som mål att studenter ska få studera några av 2000-talets funktionella material. Ett av de största ämnena inom solcellsforskning är hybrida organiska/icke-organiska perovskitsolceller eftersom de är lätta att tillverka, billiga och har potential för höga verkningsgrader. En laborationshandledning sammanställs för kursen, där studenter ska få tillverka perovskitsolceller med en uppbyggnad av FTO/TiO2/MAPbI3/CuSCN/Carbon/FTO genom användning av spin coating och anlöpning för tester i solsimulator. Verkningsgraden för dessa solceller når 0.056 %, men förslag till förbättringar när studenter ska göra solcellerna diskuteras. Absorptionsegenskaper undersöks med UV-vis-spektroskopi och bandgapsenergin hos MAPbI3 fastställs till att vara 1.59 eV. Med dessa tillverknings- och karaktäriseringstekniker får studenter möjligheten att lära sig mer om ett av de mest relevanta ämnena inom solcellsforskning, samt om hur man använder sig av utrustningen som är närvarande i hela processen.
