Ziar, H. (author), Mishra, Sandeep (author), Isabella, O. (author), Zeman, M. (author)This paper suggests a measurable parameter, the so-called Shading Tolerability (ST), to be added on PV modules datasheet. Using this parameter, PV modules can be compared and classified regarding the ability to oppose shading effects.

Tian, Y. (author), Bento Montes, A.R. (author), Isabella, O. (author), Zeman, M. (author)Regarded as a promising absorber material for solar cell applications, Barium disilicide (BaSi2) is still confronted with issues related to surface oxidation. Here, we use a-Si.H deposited by plasma-enhanced chemical vapor deposition as capping layer to prevent surface oxidation of sputtered BaSi2 films. Based on crystalline quality and...conference paper 2018

(author)Solar Home Systems (SHSs) can fulfil the basic energy needs of the globally unelectrified population. With costs as one of the biggest barriers for SHS uptake, optimizing the system size with energy needs is crucial. Where most solutions focus only on the present needs, this work also addresses the future energy needs. The methodology includes...conference paper 2017

Chandra Mouli, G.R. (author), Schijffelen, Jos (author), Bauer, P. (author), Zeman, M. (author)Magnetic cores like powdered iron cores have a variable permeability, which is dependent on the magnetic motive force of the inductor windings. When inductors are designed using such materials, the inductance varies as a function of the inductor current. This causes a non-linear current to flow through the inductor. In this paper, mathematical...conference paper 2016
