As an addendum to this question, my situation is even worse: my character is level 60, and my friend has just begun.
This translates in me getting 99.2% of the xp points.
Going to higher level areas would not help, because he would run into the level penalty.
Is there an effective way (strategy/ zone grinding) to help him level up fast without boring him do death? (I'm trying to make him like the game, not hate it)
Levelling up a gem is like levelling up a skill in many other games. It gives you higher damage, more effects, higher requirements, etc.
As you can see, burning arrow gains 3% physical damage, and 1% greater chance to ignite enemies. It also now requires you to be level 2 to use it.
I believe higher levels of Raise Zombie increase zombie health and damage. For other (non-summon) skills, the stats of the new level were shown on the gem at one point during beta, but do not appear to be shown now. The reason minion statistics aren't shown on the skill is because they don't exist on the skill, they exist on the minion.
(Minion statistical information) isn't hidden, it doesn't exist. Ideally we'd like to make it exist and be visible eventually, but this a) requires implementing entirely new systems for skills to be able to show stats that aren't in the skill, and b) requires those stats having actual values we can read somewhere. We've got a temporary solution for Zombie life numbers, which need updating any time any balance changes modify what those values are, but it's simply not viable to make that a large-scale solution.
You get more zombies from the passive tree.

There is no real way to power level someone like in other ARPG's (Diablo).
If you were to join his game as a higher level and start killing monsters, you would be getting a much higher share of the xp for being a higher level while only doubling the base xp gain from monsters. Also if you move too far away from your friend and they aren't able to keep up they won't gain any xp for monsters you killed. Both of these would probably end up slowing down the leveling process for your friend instead of speeding it up. (Wiki page on xp gain in parties)
PoE is definitely a game to be taken slowly and get a hang of all the different mechanics, spells, skill tree etc first hand. Sure you can and possibly have already told them plenty about the game but they still might not understand until actually interacting with it.
I would assure them that yes the first couple acts or so are boring on normal but the game picks up pace once you get more support gems and passive points. Just talk with them over something like Skype or curse voice just to keep them a bit more occupied while leveling and be there to answer questions they might run into.
