Title: The Innovative Contributions of Inventor Peter Bäuerle
Introduction
Peter Bäuerle, a notable inventor based in Elchingen, Germany, has made significant advancements in the field of organic photovoltaics. With two patents to his name, Bäuerle's work focuses on innovative materials and devices that enhance the efficiency and affordability of solar energy technology.
Latest Patents
Bäuerle's latest inventions include advancements in hole transport materials and organic photoactive devices. His patent for hole transport material, specifically the organic small molecule 4,4',4″,4'″-(5,5-dimethoxycyclopenta-1,3-diene-1,2,3,4-tetrayl)tetrakis(N,N-bis(4-methoxyphenyl)aniline (CPDA 1), reveals electrochemical properties closely matching those of spiro-OMeTAD. This makes CPDA 1 highly compatible with perovskite solar cell (PSC) systems. The incorporation of the cyclopentadiene dimethyl acetal core allows for a red shift in the absorption onset, facilitating optimal film properties due to its flexible spatial configuration. Analysis of transient and steady-state emissions, alongside hole mobility evaluations, indicate that CPDA 1 significantly improves charge extraction, transport, and separation compared to its reference counterpart. Notably, PSCs utilizing CPDA 1 achieve a power conversion efficiency (PCE) nearing 23% with less hysteresis and dramatically lower production costs—approximately ten times less than spiro-OMeTAD—enhancing the economic viability of PSC technology.
In addition, his patent on organic photoactive devices focuses on the development of organic photovoltaic cells featuring a photoactive region composed of a bulk heterojunction or a flat heterojunction. This structure employs oligomers such as conjugated acceptor-donor-acceptor (A-D-A') and donor-acceptor-donor (D-A-D′) types, further advancing organic photoactive materials.
