“…Then, bubbles form easily inside the adhesive, which is hazardous to solar cells in outer space. [8][9][10] Furthermore, solar cells may easily get stained by manual work, which will cause lower production rate and difficulty in cleaning operation. Due to these disadvantages, the ALR is developed to realize the autodispensing and auto-laydown operation.…”

SUMMARYThis paper discusses about auto-laydown robot (ALR), which is applied to performing the laydown process of a solar module on earth. The robot consists of an adhesive dispensing mechanism, an auto-laydown mechanism, a pneumatic system and a control system. The method of gripping solar cells is described based on pneumatic technology. Meanwhile, a new method of controlling adhesive thickness and area during dispensing is proposed in this paper. The robot realizes the automatic laydown process of solar modules and can control the laydown pressure effectively. Compared with the manual method, the robot could control the dispensing volume and the adhesive area between solar modules and panel substrates, by means of experiments. The novel ALR greatly improves the laydown quality of solar modules and meets the lightweight trend of solar cells development.

“…The spacecraft flies in the astrospace 150 km away from the earth, where the condition is extremely bad, the radiant intensity of the Sun is about 1.3 times as high as that on the Earth, the temperature fluctuates greatly, and the amount of energetic particles is big [1][2][3]. To ensure that the solar cell works reliably under this environment, it is necessary to bond the active surface of the solar cell with the anti-irradiating cover-glass to protect solar cells [6][7][8]. Based on the physical characteristic of the solar cell, there are four kinds of technologies used in bonding the cover-glass to the solar cells.…”

A space solar cell bonding robot system which consists of a three-axis Cartesian coordinate's robot, coating device, bonding device, orientation plate, and control subsystem was studied. A method, which can control the thickness of adhesive layer on the solar cell, was put forward and the mechanism was designed. Another method which can achieve the auto-bonding between thin coverglass and the space solar cell was studied and realized. It produced no air bubble in the adhesives layer under the condition of no vacuum environment, and ensures the assembly dislocation ≤0. 1 mm. Compared to the conventional method, it has advantages such as no fragment exists, and no adhesives outflow onto the cover-glass and solar cells.

Solar cells can be attached to their protective coverglass without any flexible adhesive. The devices then potentiallly have the advantages of higher ruggedness, lower mass and increased radiation hardness in high radiation environments. This paper describes the development of direct glassed (DG) GaAs solar cells, ultrathin cells (UTCs), and direct glassed ultrathin cells (DG-UTCs), for first in-orbit testing on the STRV solar cell flight experiment.To date, 4 cm2 UTCs bonded with conventional DC93-500 have been demonstrated with 1 sun AM0 (25 "C) efficiencies of up to 19.7%. Thick (280 pm) DG cells with efficiencies up to 16.3%, and 10 pm DG-UTCs of up to 17.8% have been realised. The trials have indicated several approaches to improve UTCs to avoid any performance penalty, at a moderate increase in cost over conventional unthinned cells.
