Quality control to maximize efficiency is critical in the competitive photovoltaic industry. For some time solar texture has been thought to qualitatively affect solar cell efficiency. However, through large-area, 3D measurements and areal feature parameters, quantitative correlation of texture to efficiency has only recently been obtained. We now know that ISO 3D surface parameters linearly correlate with solar cell efficiency.
In the earlier days, the chemistry involved in solar cell manufacturing was relatively simple, using commodity chemicals. With cell efficiencies continuously on the rise and new cell concepts slowly being introduced with increased speed of processing, precise chemical concentration control is becoming crucial to obtain consistency and more cost-effective manufacturing of solar panels. This is possible by monitoring on-line the etching bath composition, a small but genuine step forward in your competitive advantage....
The manufacturing process of the cells that make up the photovoltaic systems and the printed circuits require water in quantity and high quality. This water has to be managed wisely so as not to affect the productivity and the expenses of the plant.
Generating solar energy is considered `green technology`, even though the production of solar cells based on silicon predominantly uses process stages that have been common practice in the semiconductor industry for many years. As in the semiconductor industry the production of solar cells employs dangerous and environmentally harmful substances, which require abatement according to legal provisions. The production of photovoltaic cells therefore is subject to strict requirements for treatment of waste gases and...
There is no legislation to control of the proper functioning of pyranometers used to measure solar radiation installed in the PV field.
The control can be effectively carried out with portable
instruments suitable to avoid uninstalling pyranometers set in areas normally inaccessible as placed at the side of panels.
A quick test on the field assesses whether a good maintenance is sufficient to obtain a reliable measurement of the solar radiation or if it is necessary to send radiation sensors to the manufacturer...
Solar technology as a renewable energy technology is spreading around the world, with major manufacturing operations occurring in China, Germany, Spain, and the U.S. For solar photovoltaics, specialty chemicals are required for the production of the photovoltaic materials.
Energy comprises many types of modes by using complex processes to explore, extract, refine, produce and transport these products. The energy industry comprises: Fossil fuels: coal, petroleum and natural gas (conventional as well as hydraulic fracturing), including liquid propane gas and liquid natural gas. Non fossil fuels such as: hydroelectric, battery technology, hydrogen fuel cells, nuclear power. Renewable fuels such as: biofuels, hydrogen fuel cells, geothermal, solar (photovoltaic). Nuclear power.
