ANALISIS EFISIENSI SOLAR CELL TIPE GH 100 WP-72 TERHADAP INTENSITAS CAHAYA

Abstract

In utilizing solar energy to produce electrical energy, solar cells are used. A solar cell is a semiconductor element that can convert solar energy into electrical energy using the photovoltaic principle. Solar cells are utilized as a tool to convert sunlight containing photon energy to be converted into electrical energy. This research aims to understand the basic concepts of solar cells, and analyze the factors that affect the efficiency of solar cells in converting solar energy into electrical energy. Data collection was carried out using a GH 100 WP-72 solar cell, battery GTZ5S, and other supporting equipment and observations were made on the parameters of voltage, current, temperature, and light intensity. The data is processed and analyzed for relationships. The results of this test sequentially starting from the beginning of the test with a time of 15 minutes from 12.05 WIB to 12.35 WIB obtained figures for solar cell efficiency respectively of 8.63%, 10.94%, and 10.91%. For light intensity figures obtained by 229.36 W/m², 180.80 W/m², 181.31 W/m². This research is expected to contribute in increasing the efficiency of solar cells with several parameters that affect the performance of solar cells.
