pilinin performans/maliyet oranını arttırmak için, ışığın emilimi ve yük
taşıyıcıların toplanması sırasında optik ve elektrik kayıplarını azaltan yeni
yaklaşımlar gereklidir. Bu çalışmada silikon yüzeyinin daha iyi bir ışık
yönetimine yönelik çeşitli şekillere odaklandık. Bir güneş pilinin verimliliği,
gelen ışık ışını ve cihazın yüzeyi arasındaki etkileşimin özelliklerine oldukça
bağlıdır. Güneş hücresinin ışık emilimini ve verimliliğini en üst düzeye
çıkarmak için çeşitli ışık tutucu şemalar önerilmiştir. Çeşitli periyodik mikro
ve nano yüzey dokuları oluşturmak için optik litografi, nanoimprint litografi
(NIL), delik maskesi kolloidal litografi (HCL) gibi farklı litografi teknikleri
uyguladık. Önceden tanımlanmış desen transfer işlemi aşamalarından sonar, kuru
plazma aşındırma veya ıslak kimyasal aşındırma teknikleri uygulanmıştır. Çap,
periyot, derinlik gibi yapısal özellikleri değiştirilmiş ve optimize
edilmiştir. Çeşitli desenleme ve aşındırma işlem türleri ile çalışmanın
sonunda, periyodik ve rastgele-tanıtılmış-periyodik desenler, güneş pili üretim
aşamasında başarıyla uygulanmıştır. Üretilen güneş pillerinin performansları
hem optic hem de elektriksel olarak incelenmiştir.

In
order to increase the performance/cost ratio of solar cells, new approaches
reducing optical and electrical losses are necessary during the absorption of
the light and collection of charge carriers. In this work we focused on various
textures on silicon surface towards a better light management of the cell
surface. The efficiency of a solar cell strongly depends on the properties of
the interaction between the incoming light beam and the surface of the device.
In order to maximize the absorption and the efficiency of the cell, various
light trapping schemes have been proposed. We have applied different
lithography techniques such as optical lithography, nanoimprint lithography (NIL), hole mask colloidal lithography (HCL) to
generate various periodic micro and nano surface textures. After predefined
pattern transfer process steps, either dry plasma etching or wet chemical
etching techniques were applied. Structural properties of the features like
diameter, pitch size, depth were varied and optimized. With a variety of
texturing and etching process types, at the end of the study, periodic and
random-introduced-periodic patterns were successfully implemented to solar cell
fabrication step. The performances of the solar cells were investigated both
optically and electrically.
