Abstract
Disclosed are a method of forming a back reflection layer in a solar cell, a composition used therefor, and a solar cell having a back reflection layer formed by the method, which layer has superior heat-resistance and various types of durabilities, and can contribute to improving the conversion rate of solar cells and reliability during long-term use, and which method can form a back reflection layer in a solar cell easily and at low cost. The polyimide resin composition for use in forming a back reflection layer in a solar cell includes an organic solvent, a polyimide resin dissolved in the organic solvent, and light-reflecting particles dispersed in the organic solvent.
