	Objectives
	KNOWLEDGE AND UNDERSTANDING THE COURSE AIMS AT PROVIDING THE PHYSICAL AND CHEMICAL PRINCIPLES THAT GOVERN THE PROPERTIES OF MOLECULES AND MATERIALS FOR THE SUSTAINABLE DEVELOPMENT OF ELECTRO-OPTICAL DEVICES WITH BROAD TECHNOLOGICAL APPLICATIONS IN ORGANIC ELECTRONICS SUCH AS PHOTOVOLTAIC AND SOLAR CELLS, LED AND OLED AND PHOTONICS. APPLYING KNOWLEDGE AND UNDERSTANDING THE NUMERICAL EXERCISES WILL ALLOW THE STUDENT TO BECOME FAMILIAR WITH SOFTWARE PACKAGES ALREADY AVAILABLE AND LARGELY USED IN ACADEMY AND INDUSTRY, AND TO ADDRESS INDEPENDENTLY THE COMPUTATIONAL STUDY OF MOLECULAR STRUCTURES, SUPRAMOLECULAR AGGREGATES AND MATERIALS. MAKING JUDGMENTS THE STUDENT WILL BE ABLE TO CRITICALLY DISCUSS THE VALIDITY OF THE RESULTS OBTAINED IN DISCUSSIONS PROMOTED BY THE TEACHER IN THE LABORATORY GROUP. COMMUNICATION SKILLS THE COURSE WILL ENABLE STUDENTS TO ACQUIRE THE APPROPRIATE TERMINOLOGY TO DESCRIBE THE MOLECULAR PROPERTIES OF MATERIALS, ALSO BY READING ARTICLES PUBLISHED IN INTERNATIONAL JOURNALS.

	Teaching Methods
	TEACHING INCLUDES LECTURES FOR A TOTAL OF 56 HOURS (7 CREDITS), NUMERICAL AND PRACTICAL EXERCISES FOR 36 HOURS (3 CREDITS) AND LABORATORY FOR A TOTAL OF 24 HOURS (2 CREDITS). THE CLASSROOM ATTENDANCE RATE IS STRONGLY RECOMMENDED AND THAT OF LABORATORY EXERCISES IS MANDATORY. TO BE ABLE TO ACCESS TO THE FINAL EXAM, STUDENTS MUST HAVE ATTENDED AT LEAST 75% OF THE EXPECTED LABORATORY HOURS. THE ATTENDANCE VERIFICATION MODE IS ANNOUNCED BY THE TEACHER AT THE BEGINNING OF THE COURSE.

	Verification of learning
	THE ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN UNIVERSITY SCHEDULED EXAMINATION SCORED FROM 0-30. THE FINAL TEST CONSISTS OF AN ORAL EXAM. ACCESS TO ORAL EXAMINATION IS ALLOWED ONLY AFTER DELIVERING WRITTEN REPORTS OF THE LAB WORKS. THE ORAL TEST STARTS WITH A QUESTION ON THE LAB ACTIVITY MADE BY THE STUDENT, FOLLOWED BY AN INTERVIEW WITH QUESTIONS AND DISCUSSIONS ON THEORETICAL AND METHODOLOGICAL CONTENT LISTED IN THE TEACHING PROGRAM AND IS DESIGNED TO ENSURE THE LEVEL OF KNOWLEDGE AND SKILL UNDERSTANDING REACHED BY THE STUDENT, AS WELL AS TESTING THE EXPOSURE CAPACITY BY USING THE APPROPRIATE TERMINOLOGY AND THE ABILITY TO AUTONOMOUSLY ORGANIZE EXPOSURE OF THE TEACHING CONTENT.
