The Sun's corona is much hotter than the photosphere, but it is not as bright because loles allow more light from the photosphere to pass through. the granulation on the photosphere allows it to generate more energy. the corona contains fewer particles and does not have as much energy as the photosphere. the photosphere has a much stronger magnetic field and is therefore brighter.
