I use the following and do get png24-files.
////// function to png //////
function savePNG (myDocument, docPath, basename, theSuffix) {
// weboptions;
var webOptions = new ExportOptionsSaveForWeb();
webOptions.format = SaveDocumentType.PNG;
webOptions.PNG8 = false;
webOptions.transparency = true;
webOptions.interlaced = 0;
webOptions.includeProfile = false;
webOptions.optimized = true;
myDocument.exportDocument(new File(docPath+"/"+basename+theSuffix+".png"), ExportType.SAVEFORWEB, webOptions);
