Abstract

ABSTRAKPenelitian ini bertujuan untuk menentukan kualitas solar cell pada nilai fill factor (ff) dan efisiensinya ( ). Data tegangan Vi dan Ii diambil secara otomatis menggunakan software logger pro dan menggunakan analisis persamaan eksponensial . Data diambil dari solar cell merk polikristal type (99×69) mm2 yang dipaparkan di depan sumber cahaya lampu bohlam philips 100W/220V sejauh 18 cm pada Ir sebesar 983, 344 W/m2. Nilai Pmax terbesar besar berada pada sudut kemiringan 30o sebesar 0,0231 watt. ff yaitu 67%, efisiensi 22%. Pada sudut 30o tersebut arah cahaya datang tegak lurus dengan bidang solar cell. Sedangkan ff terendah kemiringan 70o yaitu 0,5362 dan efisiensi 13%. Kata kunci: Fill factor dan efisiensi solar cell; logger pro. ABSTRACTThis study aims to determine the quality of solar cell on the value of the fill factor (ff) and efficiency (h). The voltage data Vi and Ii are taken automatically using logger pro software and using exponential equation analysis. The data was taken from polycrystalline solar cell type (99×69) mm2 which was presented in front of the light source of Philips lamp bulb 100W/220V as far as 18 cm at Ir of 983, 344 W/m2.

Abstract

Abstrak- The study about fill factor and efficiency solar cell have been done with an automatic drive machine that rotates the surface of the solar cell following the movement of the light source from 0° up to 90° compared without automatic drive.  The test results are then implemented to determine the fill factor and efficiency in variations in light intensity. In this study, polycrystalline solar cell type (99 × 69) mm2, the Philips 100W/220V light bulb at a distance of 18 cm and the driving machine is controlled through an Arduino Uno R3 microcontroller. Data acquisition of current and voltage is carried out with the help of DCP-BTA current and VP-BTA voltage probes that are connected to the mini labquest transducer and displayed to a computer through loggerpro software. The result show that it has been successfully designed an automatic driver of a solar panel (99 × 69) mm2  with an Arduino Uno R3 microcontroller and a logger pro software as data acquisition software. The using solar cell automatically driven can improve the accuracy and precision of current and voltage readings so the fill factor might be increased up to 10% while the efficiency of solar cells does not change. Variations in light intensity can increase the fill factor and efficiency of solar cells. Fill factor and efficiency have an exponentially relationship to light intensity.
