摘要

With an amorphous silicon (a-Si:H)/crystalline silicon (c-Si) heterojunction structure, the heterojunction with intrinsic thin-layer (HIT) solar cell has become one of the most promising technologies for c-Si based solar cells. By replacing a-Si:H thin films with appropriate compound semiconductors, we propose novel heterojunction structures which allow c-Si heterojunction solar cells to possess higher power conversion efficiencies than HIT solar cells. Several promising heterojunction candidates and hetero-structures have been proposed in this work, and this kind of novel c-Si compound heterojunction solar cell is denominated HCT (heterojunction with a compound thin-layer). The feasibilities of these novel HCT structures are further investigated by theoretical approaches, and the modeling results demonstrate the device performance improvement. Finally, this paper proclaims the compound selection standards and essentials of achieving high-efficiency HCT solar cells, which are guidelines for the real device implementation.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
