Exploring under the same Sun
KAJANG – First batch of Material Technology apprentices, who are currently enrolled in “Solar Cell Technology” course, visited HBE Gratings Sdn Bhd; which has been established in 2010 through collaboration between Hidayat Bestari Enterprise and Gratings Inc. The main business of the company is providing solutions for monocrystalline silicon ingot, wafering, cells and photovoltaic module processes.
We were greeted by Mr. Mohd Hafiz Chin (Head of R&D) and Dr. Cheow Siu Leong (Senior Researcher) upon arrival; followed by a company presentation by Dr. Saleem H. Zaidi (Technical Director). After a short discussion and Q&A session, we were brought to their fabled processing and fabrication laboratory. The young Material Technologists or also known as Materiologists, gained new knowledge and experienced real R&D environment; focusing on modification of the surface of Silicon wafer to reduce reflected photon up to ~5% thus maximizes photon absorption.
On the processing side, a complete solar cell fabrication is demonstrated by interns and staff. The solar cells were fabricated manually; driven by knowledge-based activities to promote creativity and innovation. We were amazed by equipment used for characterizations and quality analysis; which were fabricated by themselves, headed by Dr. Saleem H. Zaidi (Technical Director) i.e., (i) LIV instrument for current and voltage measurements and (ii) photon transmission and reflectance measuring instruments. We were also brought to another laboratory at Universiti Kebangsaan Malaysia; where a setup of large scale of hybrid (solar cell-wind turbine-hydro) is being constructed.
From the visit, both parties have discussed about industrial training, academic attachment and industrial talk which could benefit the students. Furthermore, the students gave positive feedbacks by showing enthusiasm and interest in Science and appreciate the delivered knowledge very well. They were also moved and inspired by Dr. Saleem; who mentioned about the importance of having sound fundamental knowledge in order to come up with new inventions and self-fabricated device.
