Classical molecular dynamics and quantum abs-initio studies on lithium-intercalation in interconnected hollow spherical nano-spheres of amorphous Silicon
A high concentration of lithium, corresponding to charge capacity of ∼4200 mAh/g, can be intercalated in silicon. Unfortunately, due to high intercalation strain leading to fracture and consequent poor cyclability, silicon cannot be used as anode in lithium ion batteries. But recently interconnected hollow nano-spheres of amorphous silicon have been found to exhibit high cyclability. The absence of fracture upon lithiation and the high cyclability has been attributed to reduction in intercalation stress due to hollow spherical geometry of the silicon nano-particles.
Comparative Techno-Economic Analysis of Rooftop PV (RTPV) Systems in Various States in India
The growth of RTPV has been sluggish compared to ground-mounted installations. This study analyses the techno-economics of RTPV in different states with their respective net-metering (NM)/gross-metering (GM) regulations and state policies to assess the financial performance of RTPV systems. States having abundant amount of solar potential such as Karnataka, Gujarat, Rajasthan, Maharashtra and Tamil Nadu are considered. The results of this analysis show that there is a lack of favourable consumer-end economics indicated by equity Internal Rate of Return (IRR) and payback period findings.
Creating Solar "Parks" in Cities
Rooftop photovoltaic (RTPV) systems are intended to contribute 40 GW of India's 100 GW solar target. While the uptake of utility-scale solar PV systems is progressing at a steady pace, their RTPV counterparts are witnessing a slow uptake. The sluggish growth can be attributed to a lack of economies of scale, absence of accurate potential assessment, and complexity in procedures.
