For higher-efficiency solar cell structures, such as the Passivated Emitter Rear Contact (PERC) cells, to be fabricated in a manufacturing environment, potentially low-cost techniques such as inkjet printing and metal plating are desirable. A common problem that is experienced when fabricating PERC cells is low fill factors due to high series resis...
A proof of concept study for a method of determining quantitative shunt values in silicon solar cells from photoluminescence images is presented. The method is based on interpretation of the luminescence intensity around a local shunt or recombination-active defect in terms of the extracted current. The theoretical relationship between the photolum...
Global warming, as well as the energy crisis as the world approaches peak oil production, are driving a need for more sustainable, cost effective, and efficient electricity sources. High efficiency photovoltaic designs, such as the PERL and PERC, use too many high temperature processes, expensive materials and complex manufacturing methods to be co...
Many existing and emerging solar cell technologies rely on plated metal to form the front surface contacts, and aluminium to form the rear contact. Interactions between the metal plating solutions and the aluminium rear can have a significant impact on cell performance. This paper describes non-uniform nickel deposition on the sintered aluminium re...
In this paper, we present a proof of concept study for a quantitative method for shunt detection in silicon solar cells using photoluminescence imaging. The method is based on interpretation of the luminescence intensity around a local shunt in terms of the extracted current density. The theoretical relationship between the PL signal and the shunt...
An inkjet printing method for forming openings to buried semiconductor layers of silicon solar cells is described. The method uses an overlying resist as a sacrificial layer onto which a plasticiser for the resist polymer is deposited in a programmed pattern using inkjet printing. At the locations where the plasticiser is printed, the resist become...
