Abstract: A solar cell, including: a silicon substrate containing antimony, wherein silicon substrate has a first surface; an antimony-containing tunneling oxide layer covering first surface; and a doped conductive layer covering, along a thickness direction of the solar cell, a surface of antimony-containing tunneling oxide layer away from silicon substrate, where doped conductive layer contains antimony. An antimony concentration of antimony-containing tunneling oxide layer is greater than an antimony concentration of silicon substrate, and the antimony concentration of silicon substrate is greater than an antimony concentration of doped conductive layer. Along the thickness direction of the solar cell, a first antimony-containing region is formed at a side of doped conductive layer adjacent to antimony-containing tunneling oxide layer, and an antimony concentration of first antimony-containing region is greater than an antimony concentration of rest region of the doped conductive layer.

Abstract: A solar cell includes silicon substrate and stack structure. stack structure is provided on rear surface of silicon substrate along thickness direction of solar cell. Silicon substrate and stacked structure contain antimony element. Stack structure at least includes first oxide layer, first doped polycrystalline silicon layer, second oxide layer and second doped polycrystalline silicon layer which are sequentially stacked along thickness direction of solar cell. Antimony doping concentration in second oxide layer is higher than antimony doping concentration in first doped polycrystalline silicon layer. Antimony element in stack structure can be bonded with silicon element, thereby effectively improving passivation effect, solving problem of low conductivity of carriers, and thus enhancing working efficiency of solar cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects. a user equipment (UE) may transmit a first message of a four-step random access channel (RACH) procedure to a base station. The UE may receive a second message of the four-step RACH procedure. The UE may transmit a third message of the four-step RACH procedure. The UE may determine that the third message was not successfully decoded by the base station. The UE may retransmit the third message based at least in part on applying a power boosting algorithm to increase an uplink transmission power. wherein the power boosting algorithm is applied based at least in part on a power offset between the third message and the first message satisfying a threshold and a transmit power control (TPC) command not being received from the base station. Numerous other aspects are described.
