I have some points in .shp vector file and I need to convert them in .tif file with 1km x 1km resolution. The problem is – there are some points in one cell during conversion, and some values are missed. How can I convert these point without missing? Is there any function that will sum values in cell(in QGIS)?
Any suggestion are acceptable.

If you are running QGIS 2.0.1, you can import the data as delimited text layer.
It offers you to select DMS Coordinates, comma as decimal separator and EPSG:4326 as CRS.
Once you have the data loaded, you can rightclick on the layer -> Save as and choose EPSG:32632 for the output file.
I think that your issue is only a "Zoom In" problem. I'm going to render to tif these random points with Raster-> Conversion -> Rasterize (Vector to Raster) Tool (cell resolution 30 x 30) of QGIS; equivalent to your standalone Python script.
Loaded raster layer looks as if no point had been rasterized.
However, with point layer as first layer, 'Zoom In' (very low scale) in whatever point and its corresponding rasterized cell appears.

First create a corresponding grid with:
Vector / Research tool / Vector grid (polygon)
Then use the join attributes with sum:
Vector / Data management tools / Join attributes by location
And finally rasterize the polygon according to the calculated attribute:
Raster / Conversion / Rasterize
