Passivating contacts are a promising technology to enhance silicon solar cells conversion efficiency. In this paper, we present a simulation study carried out by using physical models calibrated on the basis of experimental data, aimed at understanding the electrical properties of front emitter silicon solar cells featuring top/rear poly-Si/SiO x selective contacts. Furthermore, we propose a rear...
A thickness controlled dual junction GaAs//Si solar cell for current matching was fabricated and demonstrated. The optically thin GaAs top cell grown by metal-organic vapor phase epitaxy (MOVPE) was directly integrated on the Si bottom cell by surface-activated bonding (SAB) method. Owing to the optically thin (∼300 nm) GaAs top sub-cell, the operation of current-matched dual junction cell was observed...
Passivated emitter and rear solar cells (PERC) on the p-type multicrystalline silicon substrate have become the focus of recent laboratory and industrial-based research because of its promising mass production perspective. This paper presents the most recent studies on PERC solar cells and reveals the realization of a world record efficiency of 20.8% PERC solar cell fabricated with screen printing...
Nanoscale rectennae (rectifying antennae) have been fabricated by combining rectifying organic self-assembled monolayers (SAM) with plasmonic materials because of their surface plasmon resonance (SPR) properties of capturing light. Gold antenna arrays are assembled by coating on CdSe tetrapod templates; the rectifying barrier is formed by self-assembled monolayer (SAM) of gold and electrolyte which...
