Improvement in silicon thin film solar cell efficiency

Kołodziej A., Krewniak P., Nowak S.

Opto-Electronics Review

2003

Vol. 11, No. 4

281-289

This paper presents the improved method of obtaining the stable hydrogenated amorphous silicon (a-Si:H) due to the protocrystalline nature of the Si:H materials. The latest experiments and results on silicon thin film solar cells are presented in this publication. The relation of microstructure and the efficiency of amorphous and microcrystalline silicon single photovoltaic structures as well as tandem on glass and triple on steel foil solar cell are also discussed.

Silicon thin film multijunction solar cells

Kołodziej A., Wroński C. R., Krewniak P., Nowak S.

Opto-Electronics Review

2000

Vol. 8, No. 4

339-345

The multijunction structure properties of the thin film silicon solar cells and the newest achievements are described. The operation, principle of the solar cell, is based on an effective absorption of incident light and a sufficiently long lifetime of photoexcited electrons and holes such that they can become spatially separated. There are compared different technological methods of obtaining the a-Si:H solar cells leading to their optimat optoelectronic properties. It is also shown some ideas on cells manufacturing partially based on special magnetron sputtering process.
