The screen-printed aluminum back surface field (Al-BSF) technol. is the current industry std. process for cryst. silicon solar cells but, due to the search for higher efficiency, much attention has ...

Surface passivation of perovskite grains is one of the promising methods to reduce recombination and improve stability of perovskite solar cells (PSCs). We herein report the effect of a melaminium ...

A team of solar physicists has released a new study shedding light on the fine-scale structure of the sun's surface. Using the unparalleled power of the Daniel K. Inouye Solar Telescope, built and ...

In May 2023, the journal Nature featured a cover article highlighting a breakthrough in flexible monocrystalline silicon solar cells developed by researchers at the Shanghai Institute of Microsystem ...

Abstract: GaAs structures are commonly used in concentrated solar cell application, whereas the active region of the cell requires front surface field (FSF) and back surface field (BSF) to complete ...

In this paper, we investigate the beam focusing effect in a near-field cell-free massive MIMO (CF mMIMO) system with a limited number of antenna elements at each access point. Based on the orthogonal ...

Furthermore, the tables comprise the 27.3% efficiency recently achieved by Longi for a heterojunction back contact (BC) solar cell and a 24.1%-efficient PERC cell fabricated by Trina Solar.

“To minimize recombination on the rear side, a back surface field (BSF) layer with a junction depth of 1 μm and a localized back contact is added,” the scientists said.
