Development of ultra-thin doped poly-Si via LPCVD and ex-situ tube diffusion for passivated contact solar cell applications

Investigation of H2 Plasma Incorporated ALD-TiOx Films as Hole-Selective Passivating Contacts in Crystalline Silicon Solar Cells

“…To further improve the performance of TOPCon cells, different structures applied to the front side were studied. On the basis of the TOPCon cell design concept, researchers proposed the front heterojunction structure composed of an ultrathin 20–30 nm-thick poly-Si layer and a 70–80 nm-thick TCO layer. , As opposed to an a-Si:H-based heterojunction, the use of a thin poly-Si-based heterojunction improved the J G by 0.34 mA/cm 2 . The HPT TiO x -based heterojunction proposed in this work is compatible with the current manufacturing flows of both SHJ and TOPCon cells.…”

Maximum Power Point Tracker Optimization for Phovoltaic Systems based on III-V Elements

“…There are several classifications for photovoltaic cells with a silicon base, such as monocrystalline, polycrystalline, thin film and half cut. These classifications are typically related to the manufacturing process and homogeneity of the silicon layer within the cell arrangement [12,17,27]. Each type of solar panel sharing the same base material has a similar I/V curve and frequency response.…”

“…Consequently, its efficiency becomes the main diverging factor [26]. Based on recent studies, the highest theoretical efficiency rating achievable by photovoltaic modules with silicon base material is 26.1% [27]. Understandably, engineers are trying to increase the efficiency of these modules without modifying their base material [12].…”
