Abstract

The purpose of this paper is to help those who research and develop solar cells in university laboratories and industrial sites understand the most basic and important quantum efficiency measurement and analysis method in analyzing solar cell performance. Starting with the definition of quantum efficiency, we calculate the theoretical current density according to the band gap of the solar cell material from the solar spectrum, along with a detailed introduction to the measurement and analysis methods, and measure and analyze the theoretical current density and quantum efficiency. We discuss in depth how to analyze the performance of solar cells through Quantum efficiency measurement and analysis of solar cells is a very useful method that can give intuition to solar cell performance analysis as it can analyze solar cells according to depth (front emitter, bulk, rear surface). Students and researchers who study solar cells with a deep understanding of theoretical current density and quantum efficiency measurement analysis are expected to use it as a basis for analyzing solar cell performance.

본 논문은 대학연구실과 산업현장에서 태양전지를 연구 개발하는 초년생들이 태양전지 성능 분석하는 데 있어 가장 기본적이면서도 중요한 양자효율(quantum efficiency) 측정, 분석 방법에 이해를 돕는 것을 목적으로 한다. 양자효율의 정의를 시작으로, 측정 방법, 분석 방법에 대한 자세한 소개와 함께 태양광 스펙트럼으로부터 태양전지 소재의 밴드 갭에 따른 이론적인 전류밀도를 계산하고, 이론적인 전류밀도와 양자효율 측정, 분석을 통해 태양전지의 성능을 분석하는 방법에 대해 깊이 있게 논의한다. 태양전지의 양자효율 측정 분석은 태양전지를 깊이(전면, bulk, 후면)에 따라 분석할 수 있어 태양전지 성능 분석에 직관을 줄 수 있는 매우 유용한 방법이다. 이론적 전류밀도와 양자효율 측정 분석에 대한 깊은 이해로 태양전지를 연구하는 학생과 연구원들이 태양전지의 성능 분석을 하는 데 있어 기반으로 활용할 수 있기를 기대한다.
