Sin city to smart city, or atonement by technology: an introduction
No full textThis chapter aims at proving the reader with an overview of the opportunities, challenges, open questions, and threats, inherent in the broad and somewhat ill-defined phenomenon known as the Smart City. A few key domains are identified and discussed: mobility, health and welfare, security and policing, energy, admin-istration and politics, and education. The core of the chapter is preceded by two sections that propose a historical and cultural angle presenting the Smart City as the technology-redeemed offspring of more troublesome ancestors

No full textSimulation of the effect of grain-boundaries in backside-passivated CIGS solar cells
No full textWe carry out numerical 3D simulations of CIGS cells with back-side Al2O3 passivation and point contact openings in the presence of grain boundaries in the absorber. We consider CIGS cells with different absorber thickness, from 0.35 to 3 mu mathrm{m}. For thinner absorbers (1 mu mathrm{m} or less) we observe that GBs terminating on the Al2O3 are completely or almost completely passivated, while the effectiveness of the passivation decreases for thicker absorbers. GBs terminating on the point contact, instead, significantly lower the efficiency, regardless of absorber thickness. The presence of grain boundaries and the dimension of grains should therefore be taken into consideration when optimizing the back-side point contact array geometry
On the effect of deep defects on the Voc deficit in high-GGI CIGS absorbers: A numerical study
No full textUsing numerical simulations, we investigate the effect of a deep donor known to exist at EV + 1.33 eV, as a contribution to explain the large VOC deficit of Ga-rich absorbers.. We find that uniform GGI absorbers with GGI > 0.5 suffer for the presence of this deep donor, with the VOC deficit linearly increasing with GGI. On the other hand, simulations indicate that this deep donor is unlikely to be a significant performance limiter in double-graded cells
