[ 1 ] - Solvothermal Synthesis of Cobalt and Copper Sulfides Nanoparticles with High Light Absorptance for New Solar Selective Coatings

New selective coating materials are developed and used in advanced solar collector and absorber designs with improved efficiency. Cobalt and Copper sulfides nanoparticles are high interest for absorbers of solar thermal collectors due to their optical properties and high absorptance in the solar wavelength range (> 96%). In the present work, Cobalt and Copper sulfides nanoparticles were synthes...

[ 2 ] - تهیه و بررسی ابرساختارهای سرب سولفید به‌عنوان ماده جاذب مؤثر نور خورشید

در این پژوهش، ابرساختارهای سرب سولفید با استفاده از روش حلال گرمایی و به‌کار بردن پیش ماده تک منبع سرب هیدروکسی تیوسیانات (Pb(OH)SCN) تهیه شدند. ابرساختارهای سرب سولفید در دو حلال اولئیک اسید (OA) و دی‌متیل‌فرمامید (DMF) تهیه شدند و تأثیر ریخت بر ویژگی‌های نوری آن‌ها مورد مطالعه قرار گرفت. پس از تهیه سرب سولفید ساختار بلوری ذرات با استفاده از الگوی پراش پرتو ایکس و مورفولوژی آن‌ها با میکروسکوپ ...

[ 3 ] - Development of spacecraft black thermal control coatings using the synthesized mesoporous Co3O4 pigment

The thermo-optical properties of coated surface are important for spacecraft thermal control coatings which depend on the optical properties and structure of the coating material. These coatings control the temperature by their capability of outer energy absorption and its emission. The optical properties of pigment can be improved if the pigment contains a high fraction of voids in its structu...

[ 4 ] - New high-efficiency protective coating containing glycidyl-POSS nanocage for improvement of solar cell electrical parameters

Various antireflection thin films are often used to cover glass to increase solar cell electrical parameters. In the recent years many efforts have been done to develop and improve of solar cell films with high electrical output. One of the most important challenges of obtaining of high-efficiency thin films of solar cells is creation an effective light trapping system. The new polymeric protec...
