Abstract
The paper presents the mechanism of absorption of dual laser pulse radiation by thin film of the ZnO, a-Si:H-based solar module. The authors of this paper theoretically justify the possibility of using mode of dual laser scribing of thin-film solar module (TFSM) at production stage and consider implementation of TFSM dual laser scribing. The duality is created by an additional channel of single laser pulse delay. Optic fiber serves as the delay channel. Moreover, the authors analyze the absorption of the first and second cycle of the laser pulse by TFSM thin film. The first pulse cycle is required for heating up the film to reduce the temperature gradient during the second pulse cycle absorption. The conditions of the second cycle absorption change due to the heating up by the first one. The change of this condition for the second cycle is in the laser radiation absorption range.
