Multicrystalline silicon has the benefit of being able to be manufactured cheaply through unidirectional solidification of the silicon melt in large-capacity(about a meter square) quartz crucibles, but it is inferior to monocrystalline in terms of conversion efficiency.
High module conversion efficiency, through superior manufacturing technology Guaranteed -1% to +3% Power Tolerance Entire module certificated to withstand high wind loads and snow loads(5400Pa) Anodized aluminum is mainly for improving corrosion resistance.
The market average conversion efficiency is 17%, polycrystalline silicon only have 13%, and some false cell efficiency less than 13%, compared to our cells are used are top quality, its lifespan is 25 years.
Taking as examples low-power DC/DC converters, the spread of mobile devices has resulted in conversion efficiencies that exceed 90% as a matter of course. However, it is thought that there is still room for improvement of the efficiency of high-voltage and large-current AC/DC converters.
Generally, the higher the voltage ratio is, the lower the conversion efficiency. However, the EZA series converters have realized bidirectional conversion with an efficiency of 94% or higher in both charging and discharging, by adopting advanced digital control technology.
In 2011, Toyota Central had managed an energy conversion efficiency rate of just 0.04%, but by developing a semiconductor substrates using iridium and ruthenium catalyst, they succeeded in increasing the efficiency rate a hundred-fold.
Going forward, the power generation efficiency of concentrator photovoltaic modules under actual operating conditions is expected to improve to 35%, and assuming an energy transfer efficiency of 80% from electricity to hydrogen in water electrolysis, it is anticipated that the energy conversion efficiency from sunlight to hydrogen will reach 25%.
The energy conversion efficiency of Si solar cells is highly dependent on the heterogeneity, as in the distribution of any defects or impurities, of the Si crystal substrates. Until now, there were no measurement methods to evaluate the eterogeneity of the substrate and utilize the results to predict its suitability as solar cells.
Their structure consists of a molybdenum electrode layer deposited atop a glass substrate, with a p-type CIS light absorbing layer and an n-type thin film layer(ZnO) laminated on top of these. The conversion efficiency recently obtained was achieved by improving the surface quality of the CIS light absorbing layer and improving the technology for forming the p-n junction.
The EL method visualizes the change of open-circuit voltage and the method is effective for detection of the defect or impurity concentration change in crystals. However, defect density and/or impurity concentration do not necessarily correlate with conversion efficiency and the EL method/tool does not have capability to measure electric characteristics related to cell conversion efficiency that intrinsically determines PV cell performance.
