An impurity diffusion layer forming composition, a method of manufacturing a semiconductor substrate with an impurity diffusion layer, and a method for manufacturing the solar cell element

摘要

The present invention provides an impurity-diffusion-layer-forming composition containing a compound containing a donor element or an acceptor element, a dispersion medium, and a fatty acid amide. The present invention also provides a method for manufacturing a semiconductor substrate with an impurity-diffusion layer having a step for applying the impurity-diffusion-layer-forming composition to form an impurity-diffusion-layer-forming composition layer on all or part of a semiconductor substrate, and a step for performing a heat treatment on the semiconductor substrate on which the impurity-diffusion-layer composition layer has been formed.
