SHJ has the highest efficiency amongst crystalline silicon solar cells in both laboratory (world record efficiency) and commercial production (average efficiency). In 2023, the average efficiency for commercial SHJ cells was 25.0%, compared with 24.9% for n-type TOPCon and 23.3% for p-type PERC. The high efficiency is owed mostly to very high open-circuit voltages—consistently over 700 mV—as a result of excellent surface passivation. Since 2023, SHJ bottom cells in Per. [pdf]
They are a hybrid technology, combining aspects of conventional crystalline solar cells with thin-film solar cells. Silicon heterojunction-based solar panels are commercially mass-produced for residential and utility markets.
Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps.
Silicon heterojunction (SHJ) solar cells have reached high power conversion efficiency owing to their effective passivating contact structures. Improvements in the optoelectronic properties of these contacts can enable higher device efficiency, thus further consolidating the commercial potential of SHJ technology.
The application of silicon heterojunction solar cells for ultra-high efficiency perovskite/c-Si and III-V/c-Si tandem devices is also reviewed. In the last, the perspective, challenge and potential solutions of silicon heterojunction solar cells, as well as the tandem solar cells are discussed. 1. Introduction
In the case of front grids, the grid geometry is optimised such to provide a low resistance contact to all areas of the solar cell surface without excessively shading it from sunlight. Heterojunction solar cells are typically metallised (ie. fabrication of the metal contacts) in two distinct methods.
Chinese solar module manufacturer Longi has developed a heterojunction back contact (BC) solar cell using a laser-enhanced contact optimization process that reportedly has a total effective processing time of about one-third compared to that of mainstream technologies such as PERC and TOPCon.

Various complexes of ruthenium were extensively used as a dye in both small area devices and big area panels. In this critical review article, we will discuss ruthenium complexes that were utilized to improve the performance of solar cells.
Ruthenium complexes have received particular interest as photosensitizers in DSSC application due to their favorable photoelectrochemical properties and high stability in the oxidized state, making practical applications feasible .
Furthermore, these amphiphilic ruthenium complexes have been successfully used as sensitizers for nanocrystalline dye-sensitized solar cells with efficiencies of 8.2% at an 100 mWcm −2 irradiance of air mass 1.5 solar light and ≧8.7% at lower light intensities.
Ru complexes have shown the good photovoltaic properties: a broad absorption spectrum, suitable excited and ground state energy levels, relatively long excited-state lifetime, and good (electro)chemical stability. The thiocyanate ligands are usually considered as the most fragile part of the ruthenium dyes.
