It's an interesting spin on the tired ad network model but I'm worried about the effectiveness for the advertiser. If the advertiser is looking for brand exposure, they would pay by CPM and look to maximize impressions which sounds like in your model would not generate any donations since it's click based.

For advertisers looking to generate clicks, they want qualified truly-interested people to click and go to their site and not clicks from people who are doing it for charity and have no interest in what in the advertiser's site/product. Most click based networks forbid incentivizing click actions that decrease click quality because it decreases audience quality.
