In this work, tandem amorphous/microcrystalline silicon thin-film solar modules with low output voltage, high energy yield, low light-induced degradation, and high damp-heat reliability were successfully designed and developed. Several key technologies of passivation, transparent-conducting-oxide films, and cell and segment laser scribing were researched, developed, and introduced into the production line to enhance the performance of these low-voltage modules. A 900 kWp photovoltaic system with these low-voltage panels was installed and its performance ratio has been simulated and projected to be 92.1%, which is 20% more than the crystalline silicon and CdTe counterparts. © 2014 Chin-Yi Tsai and Chin-Yao Tsai.

In this work, tandem amorphous/microcrystalline silicon thin-film large-area see-through color solar modules were successfully designed and developed for building-integrated photovoltaic applications. Novel and key technologies of reflective layers and 4-step laser scribing were researched, developed, and introduced into the production line to produce solar panels with various colors, such as purple, dark blue, light blue, silver, golden, orange, red wine, and coffee. The highest module power is 105 W and the highest visible light transmittance is near 20%. © 2014 Chin-Yi Tsai and Chin-Yao Tsai.

A thin film solar cell includes a substrate, a plurality of photovoltaic cells and at least one control unit. The photovoltaic cells generate a photocurrent respectively. Each photovoltaic cell includes a first conductive layer disposed on the substrate, a photovoltaic layer and a second conductive layer. The photovoltaic layer disposed on the first conductive layer has an opening exposing the first conductive layer. The second conductive layer disposed on the photovoltaic layer is connected electrically to the first conductive layer of the adjacent photovoltaic cell through the opening. The control unit is connected to at least one of the photovoltaic cell electrically. When the photocurrent generated by at least one of the photovoltaic cells is different from the photocurrent generated by other photovoltaic cells, the control unit provided a compensable current to the first photovoltaic cell to make the photocurrents provided by the overall photovoltaic cells being matched.

A delivery device for delivering a substrate of a solar cell includes a plurality pairs of conveyer rollers arranged along a delivering path. Each pair of the conveyer rollers includes a first and second conveyer rollers respectively having first and second axes extending perpendicularly to the delivering path, and first and second aligners disposed circumferentially and respectively on the first and second conveyer rollers. The first and second conveyer rollers are made from polytethrafluoroethylene. The first and second aligners cooperatively define a carrier region for carrying the substrate thereon for delivery.

The innovative passivation treatment has been developed for increasing the stabilized power of standard a-Si/μc-Si tandem module and building-integrated photovoltaic (BIPV) via well passivation of μc-Si material. By adopting external passivation technique, the open-circuit voltage (Voc) almost keeps in constant, furthermore, a significant improvement of Voc (∼3%) and fill factor (∼5%) could be obtained as comparing to reference ones. In the present work, a well passivation treatment for microcrystalline Si to prevent the post-oxidation of the cracks has been reported. About 9 % of improvement of degradation behavior and an outstanding performance of BIPV (93%) could be observed by this unique technique. © 2011 IEEE.
