“…Due to continuous growth rate over the last decade, the cumulative installed capacity of photovoltaics have exceeded 303 GW-peak by the end of 2016. 153 Monocrystalline silicon based PV with their long life span (up to 40 years) and high conversion efficiency (15-26%) is a better choice. 154 However, the higher cost of monocrystalline silicon (compared to amorphous or microcrystalline silicon) makes it expensive.…”

Ultra-thin chips for high-performance flexible electronics

Flexible electronics has significantly advanced over the last few years, as devices and circuits from nanoscale structures to printed thin films have started to appear. Simultaneously, the demand for high-performance electronics has also increased because flexible and compact integrated circuits are needed to obtain fully flexible electronic systems. It is challenging to obtain flexible and compact integrated circuits as the silicon based CMOS electronics, which is currently the industry standard for high-performance, is planar and the brittle nature of silicon makes bendability difficult. For this reason, the ultra-thin chips from silicon is gaining interest. This review provides an in-depth analysis of various approaches for obtaining ultra-thin chips from rigid silicon wafer. The comprehensive study presented here includes analysis of ultra-thin chips properties such as the electrical, thermal, optical and mechanical properties, stress modelling, and packaging techniques. The underpinning advances in areas such as sensing, computing, data storage, and energy have been discussed along with several emerging applications (e.g., wearable systems, m-Health, smart cities and Internet of Things etc.) they will enable. This paper is targeted to the readers working in the field of integrated circuits on thin and bendable silicon; but it can be of broad interest to everyone working in the field of flexible electronics.

“…Fifth, uncertainty ranges of wind (and sometimes solar) power output can be rather broad (see section 3.1). Options for reducing the risks posed by day-to-day variability must still be explored in systems with excellent solar/wind(/hydro) synergies, for example through storage technologies and export/ import between countries/regions [24,26,75]. Storage technologies are set to play a substantial role in power systems with high shares of renewables in the future; while synergies between solar PV and wind power can be exploited to reduce storage needs and costs, as can demand management options, that does not mean the need for storage can be eliminated.…”

“…Solar photovoltaic (PV) power has excellent technical potential in WA [25], but heavy reliance on solar PV causes balancing problems on diurnal timescales [26]. Across WA, wind power potential on its own is not estimated as particularly high [27,28]; wind speed is quite variable temporally and geographically, with the highest potential found towards the north/northwest [25,27,29,30].…”

West African countries' energy and climate policies show a pronounced focus on decarbonising power supply through renewable electricity (RE) generation. In particular, most West African states explicitly focus on hybrid mixes of variable renewable power sources-solar, wind and hydropower-in their targets for the electricity sector. Hydropower, the main current RE resource in West Africa, is strongly sensitive to monsoon rainfall variability, which has led to power crises in the past. Therefore, solar and wind power could play a stronger role in the future as countries move to power systems with high shares of RE. Considering the policy focus on diversified RE portfolios, there is a strong need to provide climate services for assessing how these resources could function together in a power mix. In this study, climate data from the state-of-the-art ERA5 reanalysis is used to assess the synergies of solar photovoltaic (PV) and wind power potential in West Africa at hourly resolution. A new metric, the stability coefficientC stab , is developed to quantify the synergies of solar PV and wind power for achieving a balanced power output and limiting storage needs. Using this metric, it is demonstrated that there is potential for exploiting hybrid solar/wind power in a larger area of West Africa, covering more important centers of population and closer to existing grid structures, than would be suggested by average maps of solar and wind resource availability or capacity factor for the region. The results of this study highlight why multi-scale temporal synergies of power mixes should be considered in RE system planning from the start.
