ke atas Sel Suria Dwi-Muka (Temperature Dependences by using Furnace Quartz Tube
on Bifacial Solar Cell) NURUL AQIDAH MOHD SININ, MOHD ADIB IBRAHIM*, SUHAILA SEPEAI, MOHD ASRI MAT TERIDI, NORASIKIN AHMAD LUDIN, KAMARUZZAMAN SOPIAN & SALEEM H. ZAIDI Institut Penyelidikan Tenaga Suria (SERI), Universiti Kebangsaan Malaysia, 43600 UKM Bangi, Selangor Darul Ehsan, Malaysia Diserahkan: 30 Jun 2017/Diterima: 9 November 2017 ABSTRAK Sel suria
digunakan untuk menawan
foton untuk menjana
tenaga. Walau
bagaimanapun, penambahbaikan sel diperlukan untuk meningkatkan jumlah penangkapan foton
dan juga untuk
meningkatkan kecekapan sel.
Ini melibatkan keseluruhan proses pembuatan sel, dengan proses penyepuhlindapan
adalah salah satu daripada langkah penting yang perlu dioptimumkan.
Percetakan perlogaman menggunakan dwi pembakaran merupakan kaedah yang
paling biasa digunakan dalam penghasilan sel suria kristal
secara komersial. Aluminium (Al) digunakan pada bahagian belakang
sel sebagai medan permukaan belakang
dan penyambung belakang
manakala perak (Ag)
dicetak pada
bahagian hadapan
sebagai grid pemungut. Proses
dwi pembakaran bagi
komponen ini adalah penting
dalam menentukan kecekapan sel. Oleh itu, dalam kajian ini, rawatan pembakaran
telah dikaji dengan menggunakan relau tiub kuarza (QTF) dengan perubahan
suhu pembakaran (700, 750, 800 and 850°C)
sebagai satu percubaan
untuk mendapatkan kecekapan
yang tinggi serta meningkatkan kesan pemirauan persimpangan Ag. Apabila suhu
meningkat, sifat
elektrik sel suria dwi-muka
juga turut meningkat.
Kebergantungan suhu menunjukkan rintangan pirau yang tinggi disebabkan
oleh proses penyejukan yang pantas selepas proses pembakaran dan
seterusnya membawa kepada faktor isi dan kecekapan sel yang
tinggi. Kata
kunci: Kebergantungan suhu; medan permukaan belakang; pemirauan
persimpangan; sel suria dwi-muka; tiub kuarza relau ABSTRACT Solar cells
are used to capture photons
to generate energy. However, cell enhancements are needed to increase the amount of photon
capture and also to increase cell efficiency. This involves the
entire cell manufacturing process, where
the annealing process is one of the
most important
steps needs to be optimized. Metallization printing using
dual combustion is the most commonly
used method in the production of commercial crystalline solar cells. Aluminum
(Al) is used on the back
of the
cell as a back
surface and rear connector while silver (Ag)
is printed
on the front as a collector
grid. The dual combustion process
for this component
is important in determining the efficiency of the cells.
Therefore, in this study, combustion treatment has been studied by using quartz
tubes furnace
(QTF) with the change of combustion
temperature (700, 750, 800 and 850°C) as an attempt to obtain high
efficiency and increase the shunting effect of Ag junction. As temperatures rise,
the electric
properties of the bifacial solar
cells also
increase. Temperature dependence shows high shunt resistances due
to rapid cooling process after the combustion process and thus leading
to fill factor and high cell
efficiency. Keywords: Bifacial solar cells; furnace
