Afin d'augmenter le rendement de conversion d'une cellule ou d'un module solaire, il est n cessaire d' tudier et comprendre minutieusement les param tres intrins ques et les ph nom nes physiques associ s. Dans cet ouvrage, on c'est int ress essentiellement l' tude de la structure interne d'une cellule solaire. L' tude de plusieurs param tres comme la texturation de surface, le dopage des couches et leurs paisseurs a permit d'extraire les param tres optimaux pour am liorer le rendement de conversion. Dans un autre volet, nous nous sommes int ress au d veloppement de plusieurs m thodes de calcul des param tres caract re analytiques et num riques avec une haute pr cision. Le test des m thodes r alis sur des composants photovolta ques qui regroupent des modules et des cellules solaires a permit d'obtenir une meilleure mod lisation diff rentes conditions ext rieures.

Hamza’s usual fun Saturday is cancelled when his family receives the sad news that Uncle Sameer has died. Follow Hamza through the day as he learns about the various aspects of a janaza. This story is a gentle introduction to attending an Islamic funeral, told from a child’s perspective. It familiarises children with the etiquettes and some of the rituals surrounding a funeral and provides an opportunity for important discussions around death and the afterlife in an age-appropriate manner.
The collected exhibition essays of Hamza Walker, former director of education at the Renaissance Society. Hamza Walker was director of education at the Renaissance Society for twenty-one years, between 1994 and 2015. During that time, he wrote essays about almost every single exhibition, both those he curated and many others curated by Suzanne Ghez. These texts were published first in the Renaissance Society’s newsletters and then eventually on the exhibition posters, which were distributed far more widely. In the course of this workman-like writing in the service of the institution, Walker developed not only his distinctive personal writing style and a keen eye but also a theory of what museum education could be and do. In his writing, Walker draws on his art's historical knowledge but looks equally to current events (both minutely local and international), insisting on the mutual relevance and related nature of the two. In Walker’s own words, “If we’re going to live up to the idea that art is for everybody, it needs a set of wider reference points,” an emphasis that has arguably shaped the identity of the institution in turn. This book collects those essays together into a volume that celebrates Walker’s brilliant, joyful, and generous writing. It also serves as a lively record of two decades of the Renaissance Society’s exhibition programming and reflects the prevalent theories, issues, and fashions of the art world during that time, not to mention the events occurring in the wider world.
