Our Services
Perovskites Materials
G4PV specializes in custom organic and inorganic synthesis, from molecular design to gram- and kilogram-scale production. Our synthetic chemistry team offers broad expertise across multi-step organic synthesis, coordination and inorganic chemistry, and specialty small-molecule manufacturing, with particular focus on materials for next-generation optoelectronic and photovoltaic applications. Core product lines include high-purity perovskite precursor materials (organic and inorganic halide salts, Cs-, FA-, and MA-based compounds) and self-assembled monolayer (SAM) molecules with custom anchoring groups and π-conjugated backbones, alongside a broad catalog of bespoke organic building blocks. Every batch is characterized by NMR, HPLC, and mass spectrometry to guarantee purity and batch-to-batch consistency. Know more from our product manual.
Perovskites Structures
General formula: ABX3
A (green): Cs+ , CH3NH3+ or CH(NH2)2+
B (dark grey): Pb2+, Sn2+ : X (red): Br- , Cl, - I-
- Perovskite Properties:
- Strong light absorption in the visible region
- Tunable band gap and remarkable defect tolerance
- Small exciton dissociation energy (<30 meV)
- 1. High efficiencies beyond that of traditional silicon photovoltaics.
- 2. Low-cost production as the materials and manufacturing processes are comparably inexpensive.
- Flexibility and versatility as the panel can be made in glass or plastic, the latter being 100 times lighter than current commercial silicon photovoltaics.
- Rapid production as low-energy solution-based processes are used.
- Potential for innovation as the product can be continuously upgraded as superior components are discovered.
- Environmental Benefits as they are based earth abundant elements, are inexpensive to fabricate and are fully recyclable.
