Following intensive research and development, Suntech Power has successfully commercialised its Pluto technology with 0.5 GW annual production capacity, delivering up to 10% performance advantage over conventional screen-printed cells. The next generation of Pluto involves the development of improved rear surface design based on the design features of passivated emitter and rear locally diffused cells. Cells with an average efficiency over 20% were fabricated on 155 cm 2 commercial-grade p-type wafers using mass-manufacturing processes and equipment, with the highest single-cell efficiency independently confirmed at 20.3%. This is believed to be a record efficiency for this wafer type. Further optimisation work on contact pattern and rear surface passivation suggests the potential for further efficiency increase approaching 23%.

Photonic (bio)electronic circuits and devices have been an enduring goal in modern photonics and electronics. Organic photoelectrochemical transistor (OPECT) interfacing light with biological world creates a substantial opportunity to this end due to the immense light−bio−matter interplay. Through modulating the invisible ionic circuit of organic electrochemical transistor (OECT) with a bipolar electrode (BPE) accommodating different semiconductor combinations, the unique photonic electronics toward logic and sensor applications are realized. Six combinations of BPEs are produced by the representative n‐type CdS/TiO2 and p‐type BiOI/NiO semiconductors, and the corresponding photonic characteristics and operation rationale are systematically investigated and explained. Designation of opto‐logic circuits and feasibility as a sensory platform are subsequently demonstrated. This work not only represents new photonic bioelectronics but also provides a generic mechanism for the design and development of advanced opto‐logics and bio‐analytics.

The full set of T cell receptors (TCRs) in an individual is known as his or her TCR repertoire. Defining TCR repertoires under physiological conditions and in response to a disease or vaccine may lead to a better understanding of adaptive immunity and thus has great biological and clinical value. In the past decade, several high-throughput sequencing-based tools have been developed to assign TCRs to germline genes and to extract complementarity-determining region 3 (CDR3) sequences using different algorithms. Although these tools claim to be able to perform the full range of fundamental TCR repertoire analyses, there is no clear consensus of which tool is best suited to particular projects. Here, we present a systematic analysis of 12 available TCR repertoire analysis tools using simulated data, with an emphasis on fundamental analysis functions. Our results shed light on the detailed functions of TCR repertoire analysis tools and may therefore help researchers in the field to choose the right tools for their particular experimental design.

As a representative intrinsic p-type inorganic semiconductor material, cuprous oxide (Cu 2 O) has been widely used in photovoltaics, catalysis, chemical industries, and other fields, owning an extremely important position. For a long time, the literature on the preparation methods and preparation technologies of Cu 2 O have been relatively scattered and independent, resulting in a certain degree of obstacles and difficulty in obtaining relevant technical knowledge and understanding the internal principles. Aiming at the progress and innovation of Cu 2 O preparation methods and technologies in recent years, combined with our team's long-term experience accumulation and research results, this article focuses on the classification, principles, and characteristics of the various Cu 2 O preparation methods and also involves representative applications and performance in the light energy utilization area. This review aims to provide reference and guidance for the preparation and research of Cu 2 O and other related inorganic oxide semiconductors.
