Yarı
iletken kuantum noktaları (QD'ler) son zamanlarda çok yönlü optik ve
elektriksel özelliklerinden dolayı güneş enerjisi dönüşümü için bir malzeme
olarak büyük ilgi görmektedir. QD tabanlı güneş pilleri (QDSSCs), yeni nesil
güneş pilleri için umut verici gelişmeler gösteren gelişen yarıiletken QD güneş
pillerinden biridir. Bu çalışmada, 1) QDSSC'lerde kuantum sınırlandırma etkisi,
2) QD'lerin çoklu eksitasyon üretimi (MEG), 3) QD'lerin üretim yöntemleri ve 4)
güneş pilleri için nanokristalli fotoelektrodlar gibi konular üzerinde
durulmuştur. Ayrıca, gelecekteki QDSSC’ler üzerine yapılacak araştırmalar için
önerilerde bulunulmaktadır. QDSSC'lerin etkinliği halen düşük olmakla birlikte,
ileride QDSSC'lerin geliştirilmesinde önemli atılımlar olacağı kanaatindeyim.

Investigation of Semiconductor Quantum Dots for Quantum Sensitized Solar Cells (QDSSCs)

Öz

Semiconductor
quantum dots (QDs) have recently attracted great interest as a material for
solar energy conversion due to its versatile optical and electrical properties.
QD-based solar cells (QDSSCs) are one of the evolving semiconductor QD solar
cells that show promising developments for the new generation of solar cells.
This work focuses on 1) quantum confinement effect in QDSSC, 2) multiple
excitation production (MEG) of QDs, 3) production methods of QDs and 4)
nanocrystalline photoelectrodes for solar cells. In addition, proposals are
made for research on future QDSSCs. Although the QDSSC's effectiveness is still
low, I believe there will be significant breakthroughs in the development of
QDSSCs in the future.
