Patent number: 9985077Abstract: The present invention relates to a serial module of organic solar cells and the method for manufacturing the same. The structure comprises a transparent conductive layer composed by a plurality of conductive blocks, an active layer having notches on the periphery, and a metal layer composed by a plurality of metal blocks. The active layer according to the present invention is a complete layer except the notches on the periphery for exposing a portion of the transparent conductive layer. The metal blocks can contact the conductive blocks of adjacent organic solar cell via the exposure areas and thus connecting the organic solar cells in series. The present invention can improves the power generating efficiency of organic solar cells in a limited space, which is beneficial to the development of promotion of future organic solar cells.Type: GrantFiled: October 17, 2014Date of Patent: May 29, 2018Assignee: ATOMIC ENERGY COUNCIL—INSTITUTE OF NUCLEAR ENERGY RESEARCHInventors: Yu-Ching Huang, De-Han Lu, Hou-Chin Cha, Cheng-Wei Chou, Chih-Min Chuang, Yeong-Der Lin, Charn-Ying Chen, Cheng-Si Tsao

Patent number: 9711722Abstract: The present invention discloses a method for improving mass-production yield of large-area organic solar cells for forming the active layer using the roll-to-roll process. The active layer includes low-bandgap high-polymer PTB7, Fullerenes derivative PC71BM, and high-boiling-point additives. The addition of the high-boiling-point additives can enhance the efficiency of organic solar cells effectively. In the roll-to-roll process according to the present invention, the drying temperature for the wet film is controlled for controlling the content of additives in the dry film. Thereby, the stability of the overall mass production and the device yield can be both improved.Type: GrantFiled: December 15, 2015Date of Patent: July 18, 2017Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Yu-Ching Huang, Hou-Chin Cha, De-Han Lu, Chih-Min Chuang, Zheng-Lin Yu, Chia-Te Yen, Yeong-Der Lin, Charn-Ying Chen, Cheng-Si Tsao

Patent number: 9269904Abstract: A method for manufacturing large-area organic solar cells utilizes a hot solvent vapor annealing manufacturing process while manufacturing the organic solar cells via a large-area proceeding method, such as spraying. Namely, a heated solvent vapor is utilized to modify an active layer after the active layer of the organic solar cells is formed, which ensures a flatness and an uniformity thereof and increases a crystallinity of the active layer and an element charge transport rate so that a power conversion efficiency of the large area organic solar cells is increased, a proceeding time is quite short, and the performance thereof is quite obvious. Therefore, the method not only reduces the cost by a large area production but obtains organic solar cells with higher conversion efficiency.Type: GrantFiled: October 2, 2013Date of Patent: February 23, 2016Assignee: Atomic Energy Council—Institute of Nuclear Energy ResearchInventors: Yu-Ching Huang, Hou-Chin Cha, Fan-Hsuan Hsu, Cheng-Wei Chou, De-Han Lu, Yeong-Der Lin, Chih-Min Chuang, Charn-Ying Chen, Cheng-Si Tsao

Patent number: 9196852Abstract: A method for manufacturing membrane layers of organic solar cells by roll to roll coating utilizes a roll to roll process for manufacturing an electron transferring layer and an active layer of the organic solar cells is disclosed. The roll to roll process adopted by the method cooperates with a particular solvent and accompanies a parameter control such as temperature and processing time during the sintering and baking steps. The method utilizes a slot-die coating technique in the interim, whereby a membrane layer of the solar cells can be manufactured with a large area for reducing the cost, and the formed membrane layers can have a good efficiency.Type: GrantFiled: October 29, 2013Date of Patent: November 24, 2015Assignee: Atomic Energy Council—Institute of Nuclear Energy ResearchInventors: Hou-Chin Cha, Yu-Ching Huang, Chih-Min Chuang, Cheng-Wei Chou, De-Han Lu, Yeong-Der Lin, Charn-Ying Chen, Cheng-Si Tsao
