Abstract

This study concentrates on finding a possible method of annealing amorphous silicon solar modules degraded by prolonged exposure to light. The aim of annealing is the recovery of initial efficiency. This should be done on the module's work site or through simple indoor maintenance. Ideally the annealing temperature should be as low as possible and the annealing time as short as possible. The annealing process of laboratory cells and commercially available triple junction solar modules was performed at temperatures 70°C - 110°C The degree of efficiency recovery as a function of temperature and time of exposure to heating was investigated. The influence of factors affecting the rate of degradation and recovery such as short-circuiting, work under load or exposure to light, were also taken into account.
