PbSe nanorod-quantum dot bulk nano-heterojunction solar cells generating multiple excitons with record photo conversion efficiencies
Kolay, İrem; Asil Alptekin, Demet (2023-06-01)
Multi-exciton-generation (MEG) process is critical due to its potential to push solar cell photoconversion efficiencies (PCEs) beyond theoretical limits. However, cells with this feature are rare, as the demonstration of t...
Probing the Förster Resonance Energy Transfer Dynamics in Colloidal Donor-Acceptor Quantum Dots Assemblies
Khalid, Muhammad Adnan; Mubeen, Muhammad; Mukhtar, Maria; Siddique, Zumaira; Sumreen, Poshmal; Aydın, Firdevs; Asil Alptekin, Demet; Iqbal, Azhar (2023-01-01)
In this article, we report the synthesis of graphene quantum dots (GQDs) by hydrothermal method and surface modified CdS quantum dots (QDs) via the colloidal method and the fabrication of their dyad. The CdS QDs functional...
Effect of surface ligands on the photoinduced electron transfer rate and efficiency in ZnO quantum dots and graphene oxide assemblies
Khalid, Muhammad Adnan; Mubeen, Muhammad; Mukhtar, Maria; Sumreen, Poshmal; Naz, Bushra; Aydın, Firdevs; Asil Alptekin, Demet; Iqbal, Azhar (2023-01-01)
Apart from biocompatibility, ZnO quantum dots (QDs) are considered to be an efficient luminescence material due to their low cost and high redox potential. Here, we report the synthesis of ZnO QDs by using five different f...

aydın, firdevs; Asil Alptekin, Demet; Kolay, İrem; Balıkoğlu, Bensu (2021-10-28)
Kurşun Selenyum Nano çubuk Temelli Nano Heteroeklem Güneş Hücreleri: Delik Taşıma Katmanının Cihaz Performansına Etkisi
Kolay, İrem; Asil Alptekin, Demet (2021-10-28)
Kurşun selenyum kuantum nokta ve kurşun selenyum nanoçubuk temellı̇ nano heteroeklem güneş hücrelerı̇nı̇n gelı̇ştı̇rı̇lmesı̇
Asil Alptekin, Demet (2021-09-02)
Teorik sınırlarına ulaşan kristal silikon teknolojisi ile güneş enerjisinden daha etkin bir şekilde yararlanmak amacıyla üçüncü nesil güneş pilleri geliştirilmektedir [1]–[5]. Güneş hücrelerinin %33 teorik limitinin (S...
KURŞUN SELENYUM KUANTUM NOKTA VE KURŞUN SELENYUM NANOÇUBUK TEMELLİ NANO HETEROEKLEM GÜNEŞ HÜCRELERİNİN GELİŞTİRİLMESİ
Kolay, İrem; Asil Alptekin, Demet (2021-09-02)
PbTe Quantum Dots and Engineering of the Energy Band Alignment in Photovoltaic Applications
Haciefendioğlu, Tuğba; Asil Alptekin, Demet (2021-09-01)
Lead telluride (PbTe) quantum dots, despite being considered as one of the most promising candidates for future photovoltaics owing to their higher multiple exciton generation yields, have received limited attention in sol...
