![]() The solar cell service lifetime as quantified by the T80 (the time required for the power conversion efficiency to drop to 80% of its starting value) is a useful metric to assess stability. Halide perovskites are promising photovoltaic (PV) materials with the potential to lower the cost of electricity and greatly expand the penetration of PV if they can demonstrate long-term stability under illumination in the presence of moisture and oxygen. Production of electricity without fuel from the environmental changes and fluxes requires a durable infrastructure for a more ยป cost-effective utilization of the "semi-perpetual" energy resources = , Environmental changes are under-used in energy production, although people are exposed to daily and seasonal changes of the environment, which include changing air temperature, pressure, humidity, and composition, tidal changes of the gravitational field, and less periodic changes of the geo-magnetic and electric fields. Flux examples are mechanical motions of air and water, surface waves and tides, heat fluxes due to a temperature gradient, solar light, and a chemical flux (such as humidity propagation in the atmospheric air or diffusion of salt in water due to a gradient of salinity at the mouth of a fresh-water river flowing into an ocean). One can produce electricity from mechanical, chemical, thermal, electromagnetic (light), or another physical flux, or from a change of temperature, chemical composition, or a physical field: gravitational, magnetic, electric, mechanical stress and strain, etc. In general, electric energy can be harvested from a flux in the environment or from a change of the environment itself. Photovoltaic solar panels convert an electromagnetic flux of light into direct current (DC). The greater the number of analysts giving a specific recommendation, the higher weight you may want to use when applying these ratings to your own analysis.Most power plants produce electricity by converting a mechanical motion into alternating current (AC). The information presented on the graph represents the number of industry analysts that currently rank the stock on the 1 to 5 scale. These recommendations are updated each day and are assigned a rating on a scale of 1 to 5: ![]() The Ratings Breakdown table uses Zacks' brokerage recommendations. This graph is intended to provide a snapshot of the short-term trend in analyst sentiment. To calculate the Mean Recommendation, the number of recommendations for a given rating is multiplied by its factor (1 thru 5, as shown below), the totals are summed, and the average is then calculated by dividing the sum by the total number of recommendations received for the period. The table shows the mean historical analyst recommendation for the current period, along with the previous 1, 2, and 3 periods. Above the chart, you will find the 12-Month High, Mean, and Low Target Prices from analysts who provided ratings. The chart at the top shows a one-year chart for the symbol, with Earnings highlighted. ![]() Analyst Ratings typically are tied into analysis of Earnings Estimates and Earnings Estimates Revisions. Unlike Barchart Opinions (which calculate the Buy/Sell rating using a variety of short-medium and long-term technical indicators), the Analyst Ratings are more of a short-term indicator that gives you a feel for how outside industry experts are weighing in on a stock. Analyst Ratings are available for US and Canadian equities. Barchart provides Analyst Ratings to give you another tool to gauge the possible future performance of a stock.
