    Celule solare bazate pe filme subțiri CDTE:MN [Articol]
    (Editura USM, 2024) Suman, Victor; Potlog, Tamara; Morari, Vadim; Ghimpu, Lidia; Enăchescu, Marius
    Heterostructures based on CdS/CdMnTe are being studied due to their semiconducting properties evidenced with a potential use in photovoltaics and their indispensability. Thin film solar cells generate the development of new practical and cost-effective alternative energy sources. The CdMnTe material is used together with CdTe as an absorber top layer in photovoltaic cells. Thus, HJ based on CdS/Cd MnTe as an alternative of cadmium telluride has been studied. In this study, the physical properties were studied, which demonstrate a cubic zinc blende structure and polycrystalline nature of CdMnTe layers. SEM micrographs of CdMnTe thin films demonstrate a homogeneity of the grains with a size between 3-5 μm, the thickness of the layers ranging between 5-6 μm. Examination of the physical properties of the CdS/CdMnTe solar cells revealed a conversion efficiency of 10.29 % with a filling factor of 61.63.

    Convertoare fotovoltaice TiO 2 / p -CdTe Ş I TiO 2 / n -CdSe [Articol]
    (CEP USM, 2014) Dumitriu, Petru; Potlog, Tamara
    În această lucrare este descris procesul de fabricare şi proprietăţile fotoelectrice ale convertoarelor fotovoltaice bazate pe structurile TiO2/CdSe şi TiO2/CdTe. Cele mai bune valori ale tensiunii circuitului deschis şi ale densităţii curentului de scurtcircuit pentru structura TiO2/CdSe sunt 0,43 V şi, respectiv, 9,12 mA/cm2 , iar pentru dispozitivul cu CdTe – 0,59 V şi 9,5 mA/cm2, respectiv. Eficienţa cea mai ridicată pentru structura TiO2/CdSe este de 1,63%, iar pentru TiO2/CdTe – de 1,98%
