Design and fabrication of color coatings for high-performance building-integrated photovoltaics

Abstract

Outside materials used on a building’s exterior must have high transmittance and excellent aesthetic design. The optimum design was achieved in this study by calculating the optical properties and color distribution to fabricate a high-quality multilayer color thin film through sputtering, and a silicon solar panel was equipped with transmissive- and reflective-type color optical thin films. A three-layer color thin film with a Nb2O5/SiO2/Nb2O5 structure exhibited an average transmittance of over 85.96% and a clear blue color. Simultaneously, it maintained a high overall efficiency with a maximum output value greater than 99% of the value of a reference silicon solar cell. Therefore, the sputtered multilayer thin-film coating not only offers a facile approach to manufacture colorful solar panels, but also has great potential for various industrial applications such as building-integrated solar power generation, automobile production, and glass production.

Artificial sensory system based on memristive devices

“…[3,[33][34][35][36] At the fundamental level, memristors have a relatively simple two-terminal structure that can change its resistance state based on the applied voltage and current history. Depending on the degree of retainment of the resistance state, memristors are classified as volatile [37][38][39][40] and non-volatile memristors. [41][42][43][44] In the case of a volatile memristor, the resistance state temporarily changes from a high resistance state (HRS) to a low resistance state (LRS), when a voltage above a threshold value is applied.…”
