Crystalline silicon thin-film (cSiTF) solar cells are an attractive alternative to bulk silicon solar cells. At Fraunhofer ISE we follow the concept of the epitaxial wafer equivalent (EpiWE), where 20 µm of silicon are deposited epitaxially by high

The formation of pn junctions and surface passivation by rapid thermal processing is being proved as a new and competitive method for silicon solar cell production. As the main process mechanisms are enhanced, the total process time at high temperatu

Rapid thermal processing is opening new possibilities for a low-cost and environmentally safe silicon solar cell production, keeping the process time at high temperature in the order of 1 min, due to enhanced diffusion and oxidation mechanisms. Contr

All work published so far on C-SiTF on ceramics was based on either non-conductive ceramics, or on "model" ceramics never able to cope with the cost requirements. For a wafer equivalent approach, where c-Si films on substrate can be directly processe

This paper suggests epitaxy of silicon for emitter formation by high temperature CVD as an alternative to conventional processing for standard silicon wafer solar cells. Epitaxy could provide an alternative method to create an adjustable emitter shap

Proceedings of 1994 IEEE 1st World Conference on Photovoltaic Energy Conversion - WCPEC (A Joint Conference of PVSC, PVSEC and PSEC).
In this paper, the authors investigate the simultaneous processing of the emitter junction and the emitter surface passivation by rapid thermal annealing (RTA) from a doped spin-on glass (SOG). Test structures and solar cells of different emitter pro

In a study we applied different solar cell processes of varying complexity to several different directionally solidified mc-Si materials. The materials differed with respect to the crystallization velocity, planarity of the crystallization interface,

Simultaneous diffusion of phosphorus and aluminum by rapid thermal processing (RTP) in the order of one minute is used to realize emitter and back surface field in a single high temperature step, with controlled surface concentration of the dopant in

Lifetime mappings are common tools for assessing the quality of mc-silicon for solar cell production. Nevertheless it is a difficult problem to directly relate lifetime mappings to overall solar cell parameters. This paper intends to show that this c
