Beyond estab­lished exper­tise in inor­gan­ic rare earths and per­ovskite raw mate­ri­als, ChemWhat has suc­cess­ful­ly rede­fined its pres­ence in the field of organ­ic opto­elec­tron­ics. The com­pa­ny has devel­oped a com­pre­hen­sive prod­uct line that encom­pass­es small mol­e­cules, poly­mers, and fullerene deriv­a­tives, cur­rent­ly serv­ing over one hun­dred research insti­tu­tions and enter­pris­es around the globe.

Core Mate­ri­als Portfolio

ChemWhat’s exten­sive port­fo­lio includes crit­i­cal inter­me­di­ates and monomers designed for high-per­­for­­mance elec­tron­ic donor and accep­tor mate­ri­als. This fea­tures key series such as Thio­phene, BTP, BDT, BDD, IDT, IDTT, BT, DPP, and IC, which serve as the essen­tial build­ing blocks for advanced poly­mer and non-fullerene devices.

Our spe­cial­ized offer­ings extend to Cova­lent Organ­ic Frame­work (COF) and Met­al-Organ­ic Frame­work (MOF) lig­ands, address­ing the grow­ing demand for next-gen­er­a­­tion opto­elec­tron­ic mate­ri­als. These inno­v­a­tive com­pounds rep­re­sent a strate­gic expan­sion of our capa­bil­i­ties, sup­port­ing research in emerg­ing pho­to­volta­ic archi­tec­tures and hybrid mate­r­i­al systems.

Indus­try-Lead­­ing Fullerene Technologies

A stand­out com­po­nent of this line­up is the Fullerene C60 deriv­a­tive, PC61BM. Wide­ly rec­og­nized as a bench­mark mate­r­i­al, PC61BM plays a piv­otal role not only in Organ­ic Solar Cells (OSCs) but also in Per­ovskite Solar Cells (PSCs), where it func­tions as a high­ly effi­cient Elec­tron Trans­port Lay­er (ETL) and grain bound­ary pas­si­va­tor. To address the var­ied require­ments of uni­ver­si­ties, R&D cen­ters, and com­mer­cial man­u­fac­tur­ers, ChemWhat has stan­dard­ized PC61BM into two dis­tinct puri­ty lev­els : 99.5% for gen­er­al research and 99.9% for high-pre­­ci­­sion device fabrication.

Com­mer­cial Suc­cess & Strate­gic Partnerships

ChemWhat’s mate­ri­als have achieved com­mer­cial val­i­da­tion, with our prod­ucts already inte­grat­ed into com­mer­cial devices cur­rent­ly avail­able in the mar­ket. This real-world deploy­ment demon­strates the reli­a­bil­i­ty and per­for­mance of our organ­ic pho­to­volta­ic mate­ri­als under demand­ing oper­a­tional conditions.

We are active­ly engaged in con­fi­den­tial devel­op­ment projects under non-dis­­­clo­­sure agree­ments (NDA) with lead­ing OPV com­pa­nies, work­ing on next-gen­er­a­­tion mate­ri­als that push the bound­aries of organ­ic solar cell effi­cien­cy and stability. 

Advanced Non-Fullerene Accep­tor Portfolio

Rec­og­niz­ing the industry’s tran­si­tion toward non-fullerene accep­tor (NFA) tech­nolo­gies, ChemWhat has devel­oped a com­pre­hen­sive range of state-of-the-art NFA mol­e­cules. Our port­fo­lio includes :

• FCC-Cl – High-per­­for­­mance chlo­ri­nat­ed accep­tor for enhanced device efficiency

• Y6 – Bench­mark nar­row-bandgap accep­tor achiev­ing record pow­er con­ver­sion efficiencies

• O-IDT­BR – Rho­­da­­nine-based accep­tor opti­mized for solu­tion processing

• L8-Th-Cl – Thio­phene-sub­­sti­­tut­ed accep­tor with enhanced crystallinity

• COT­IC-4Cl – Chlo­ri­nat­ed COT­IC series for improved charge transport

• COT­IC-4F – Flu­o­ri­nat­ed COT­IC vari­ant deliv­er­ing supe­ri­or pho­to­volta­ic performance

These NFA mate­ri­als rep­re­sent the fore­front of organ­ic pho­to­volta­ic tech­nol­o­gy, offer­ing supe­ri­or light har­vest­ing, charge trans­port, and device sta­bil­i­ty com­pared to tra­di­tion­al fullerene-based systems.

Tech­ni­cal Excel­lence & Cus­tomer Support

Cru­cial­ly, ChemWhat dis­tin­guish­es itself through its ser­vice mod­el. Rec­og­niz­ing the com­plex­i­ties inher­ent in organ­ic pho­to­volta­ic research, ChemWhat’s tech­ni­cal engi­neers pro­vide ded­i­cat­ed sup­port to R&D clients. Whether assist­ing with mate­r­i­al selec­tion or trou­bleshoot­ing appli­ca­tion issues in spe­cif­ic device archi­tec­tures, these experts help bridge the gap between raw chem­i­cal syn­the­sis and opti­mal device per­for­mance, ensur­ing researchers max­i­mize the poten­tial of these advanced materials.

Our tech­ni­cal team’s deep under­stand­ing of both COF/MOF chem­istry and OPV device physics enables us to pro­vide com­pre­hen­sive guid­ance on mate­r­i­al selec­tion, pro­cess­ing opti­miza­tion, and per­for­mance enhance­ment strate­gies tai­lored to each client’s spe­cif­ic research objectives.

Future Vision & Mar­ket Leadership

Look­ing for­ward, ChemWhat is com­mit­ted to lever­ag­ing the nat­ur­al advan­tages of organ­ic solar ener­gy — specif­i­cal­ly its semi-tran­s­­paren­­cy, flex­i­bil­i­ty, supe­ri­or low-light per­for­mance, and high pow­er-to-weight ratio. By sup­ply­ing these cut­t­ing-edge mate­ri­als, the com­pa­ny is active­ly empow­er­ing down­stream part­ners to devel­op inno­v­a­tive solu­tions for Build­ing Inte­grat­ed Pho­to­voltaics (BIPV), the Inter­net of Things (IoT), and the demand­ing fron­tiers of space exploration.

Our strate­gic focus on com­mer­cial via­bil­i­ty, evi­denced by our mate­ri­als’ pres­ence in mar­ket-ready devices and ongo­ing NDA part­ner­ships, posi­tions ChemWhat as a trust­ed part­ner for com­pa­nies seek­ing to tran­si­tion from lab­o­ra­to­ry research to com­mer­cial pro­duc­tion. We con­tin­ue to invest in expand­ing our NFA port­fo­lio and devel­op­ing next-gen­er­a­­tion mate­ri­als that will define the future of organ­ic optoelectronics.

Through this com­pre­hen­sive approach com­bin­ing proven fullerene tech­nolo­gies, inno­v­a­tive COF/MOF mate­ri­als, cut­t­ing-edge NFA mol­e­cules, and unpar­al­leled tech­ni­cal sup­port, ChemWhat stands at the fore­front of the organ­ic opto­elec­tron­ic rev­o­lu­tion, enabling the next gen­er­a­tion of sus­tain­able ener­gy solutions.
