Solar cells rely on the efficient generation of electrons and holes subsequent collection these photoexcited charge carriers at spatially separated electrodes. High wafer quality is now commonplace for crystalline silicon (c-Si) based solar cells, meaning that cell's efficiency potential largely dictated by effectiveness its carrier-selective contacts. The majority contacts currently employed i...
This paper discusses the historical beginnings and current state of knowledge synthesis organosilicon compounds chlorine derivatives silicon. The key importance these for modern industry, including semiconductor industry (photovoltaic cells, microprocessors, memory chips many other electronic elements) is highlighted. Significant environmental threats related to production research challenges a...
Silicon is as an essential element for crops and an important food source for the growth of rice plant. If no adequate replacement for this element, plants are faced with a shortage of silicon causing serious eating disorder and instability in plant resistance to pests. This research was done to investigate the effect of silicon on growth, yield and tolerance to rice stem borer in Tarom Hashemi...
An analytical protocol for the accurate and precise determination of Si in naphthas is presented by using ICP-OES, optimizing from the sample preparation to the measurement conditions, in order to be able to analyze for the first time silicon contents below 100µgkg-1 in a relatively short time thus being used as a control method. In the petrochemical industry, silicon can be present as a contam...
