How Solar Cells Work

When a photon with sufficient energy impinges upon a semiconductor it can transfer enough energy to a electron to free it from the bonds of the semiconductor’s valence band so that it is free to move and thus carry an electric current. The junction in a semiconductor diode provides the necessary electric field to cause the current to flow in

Problems in Estimating Battery Lifetimes

Determining battery lifetimes is beset with difficulties. Performance data are not generally available and costly to generate since large numbers of batteries must be tested to destruction. Furthermore, the required test period to verify the predictions is often greater than commercial decision lead time. Charge – discharge times for high capacity batteries are very long and using accelerated life testing

Without wild pollinators, yields of food crops dependent on pollination could fall by 25-32%

A recent article by JRC scientists published in the journal Land has mapped and assessed the pollination potential for food crops at European scale. This helps estimate the contribution of wild pollinator insects to crop production and identify landscape areas in Europe with a deficit in potential pollination. Assessing large-scale patterns of the availability of pollination services and identifying potential

Global CO2 emissions per region from fossil-fuel use and cement production

This is a chart from JRC. The September announcement of the Inter-governmental Panel for Climate Change (IPCC), paints a grim picture of the Earth’s future climate system. Global surface temperatures likely to exceed 1.5° C and pass beyond the threshold of 2° C, with the worst scenario projecting an increase of up to 4.8° C compared to 1986-2005. Sea level

Automated guided vehicle

An automated guided vehicle or automatic guided vehicle (AGV) is a mobile robot that follows markers or wires in the floor, or uses vision or lasers. They are most often used in industrial applications to move materials around a manufacturing facility or a warehouse. Application of the automatic guided vehicle has broadened during the late 20th century. Automated guided vehicles

How to prolong lithium battery

The lithium-ion battery works on ion movement between the positive and negative electrodes. In theory such a mechanism should work forever, but cycling, elevated temperature and aging decrease the performance over time. Since batteries are used in demanding environmental conditions, manufacturers take a conservative approach and specify the life of most Li-ion between 300 and 500 discharge/charge cycles. Counting cycles
