    Portable solar stove
    (Nazarbayev University, 2013) Hazken, S.; Aidarkhanov, D.
    The project uses Fresnel lens to concentrate the sunlight as it has more light and is more compact than reflectors. Fresnel solar cookers can heat foodstuff up to oil boiling temperatures, so it can cook more kind of foods. The lens concentrates light at the bottom of the cooking vessel, and the light path lies within the frame of the cooker. This makes it safer than parabolic concentrators. The last advantage is the modular and compact design which makes the whole device easy to transport where it may be necessary – outdoor trips, camping, or remote working fields.

    Simulation of stationary and dynamic responces of organic solar cells
    (Nazarbayev University, 2013) Aidarkhanov, D.; Raba, A.; Leroy, Y.; Cordan, A.-S.
    The model allowed distinguishing different regimes of the charge transport. It was shown that 2D time-dependent model can be applied to simulate transient photocurrent measurements in order to study sweep-out and recombination kinetics of the charges in the organic solar cells. The model can supply qualitative description of the transient processes in addition to the quantitative description of the simulated bulk heterojunction organic solar cells.
