Combining electron- and hole-selective materials in one crystalline silicon (Si) solar cell, thereby avoiding any dopants, is not considered for application to photovoltaic industry until only comparable efficiency stable performance are achievable. Here, it demonstrated how a conventionally unstable electron-selective contact (ESC) optimized with huge boost stability as well improved electron transport. With the introduction of Ti thin film between a-Si:H(i)/LiF Al electrode, high-level...
Abstract Crystalline silicon solar cells with regular rigidity characteristics dominate the photovoltaic market, while lightweight and flexible thin crystalline significant market potential have not yet been widely developed. This is mainly caused by brittleness of wafers lack a solution that can well address high breakage rate during fabrication. Here, we present reinforced ring (TSRR) structure, which successfully used to prepare free-standing 4.7-μm 4-inch wafers. Experiments simulations...
Dopant‐free heterojunction (HJ) solar cells are known for their simple process conditions and low parasitic absorption. However, stability issues remain one of the major obstacles further development with transition metal oxides (TMOs). Therefore, this research demonstrates mechanism thermal annealing degradation effects on TMOs/silicon (Si) HJ, namely, infiltration oxygen from air bidirectional diffusion TMOs, by investigating a typical molybdenum oxide (MoO x )/Si contact. A dense Au...
Specific contact resistance ( ρ C ) plays a significant role in determining the efficiency of dopant‐free heterojunction (DFHJ) silicon solar cells. Existing methods allow accurate measurement only majority carrier collection region. Herein, taking heterojunctions transition metal oxide/c‐Si(n) as an example, how to extract from minority (hole) region by ingeniously using expanded Cox and Strack method is demonstrated. On basis technology computer‐aided design double (diode + resistance)...
Dopant-free passivating contacts have the potential to be deposited at low costs while exhibiting excellent electrical performance for photovoltaic devices. However, one significant issue of such a technology is unsatisfactory environmental stability compared conventional doped-silicon contacts. Herein, we present strategy improving and properties typical electron-selective (ESCs) with i-a-Si:H/LiF/Al stack by inserting thermally evaporated thin metal films as protective layers....
Crystalline silicon solar cells dominate the photovoltaic market nowadays. However, they are rarely used in self‐powered systems (with an operating voltage of 1.5∼12.0 V) mainly because low integration cell modules, which need slicing and then series connection. Herein, a series‐interconnected can be prepared on monolithic wafer, with capability to output high by controlling number sub‐cells, is proposed. Further, based technology computer aided design (TCAD) numerical simulation, in‐depth...
