Journal ArticleDOI
Improved quantitative description of Auger recombination in crystalline silicon
TL;DR: In this article, the injection-dependent carrier recombination for a broad range of dopant concentrations of high-purity $n$-type and $p$)-type silicon wafers passivated with state-of-the-art dielectric layers of aluminum oxide or silicon nitride was studied.
Journal ArticleDOI
Reassessment of the Limiting Efficiency for Crystalline Silicon Solar Cells
TL;DR: In this article, the influence of the improved state-of-the-art parameters on the limiting efficiency for crystalline silicon solar cells under 1-sun illumination at 25°C, by following the narrow-base approximation to model ideal solar cells was analyzed.
Journal ArticleDOI
Passivated rear contacts for high-efficiency n-type Si solar cells providing high interface passivation quality and excellent transport characteristics
TL;DR: In this paper, a passivated rear contact is used to replace point contact passivation schemes for high-efficiency n-type crystalline silicon solar cells, which is based on an ultra-thin tunnel oxide (SiO2) and a phosphorus-doped silicon layer.
Journal ArticleDOI
n-Type Si solar cells with passivating electron contact: Identifying sources for efficiency limitations by wafer thickness and resistivity variation
Armin Richter,Jan Benick,Frank Feldmann,Frank Feldmann,Andreas Fell,Martin Hermle,Stefan W. Glunz,Stefan W. Glunz +7 more
TL;DR: In this article, the efficiency of n-type silicon solar cells with a front side boron-doped emitter and a full-area tunnel oxide passivating electron contact was studied experimentally as a function of wafer thickness W and resistivity ρ b.
Journal ArticleDOI
A review and comparison of different methods to determine the series resistance of solar cells
TL;DR: In this paper, the authors present a review of five different methods to determine the series resistance RS of solar cells and an experimental investigation of these to find the most reliable and robust method(s) for cell characterization under operating conditions.
