We investigated the mechanism of the degradation mode spreading from interconnectors, a phenomenon that is frequently observed for crystalline silicon photovoltaic modules after damp heating or pressure-cooker testing (PCT). Modules tabbed by solderi

In this article, we investigated the internal quantum efficiency (IQE) properties of n-type bifacial interdigitated back contact crystalline silicon solar cells using an IQE mapping system. In the cell structure, high and low IQE values were observed

We propose a physical mechanism that explains the local contact formation stimulated by the aluminum-silicon (Al-Si) interdiffusion within the various widths of Al rear grid for bifacial-passivated emitter and rear cell (Bi-PERC). The rear sides of B

This paper presents the development of industrial-sized p-type passivated emitter and rear cells (PERCs) with a selective emitter (SE) structure. We focus on different assisted passivation schemes and use nitric acid oxidation of silicon (NAOS) to fo

We attempted to improve the performance of passivated emitter and rear cells by increasing the quality of the aluminum back surface field (Al-BSF) beneath the local contact. We demonstrate that a thicker Al-BSF can be obtained by adding Si to the scr
