Silicon heterojunction solar cells have been the subject of growing research interest. Such cells replace the typical p+nn+ or n+pp+ structure of standard devices with selective heterojunction contacts, which block one type of carrier while allowing the other to pass freely (Fig. 1) [1-3]. Previously [4], we demonstrated a PEDOT/n-Si/TiO2 heterojunction cell fabricated below 100°C with no p-n junctions...
The successful transfer printing of thin metal films onto monolayers of aliphatic bisphosphonic acids (bisPAs) is reported. These monolayers were prepared from solution on plasma-grown aluminum oxide, and were compared with analogous monolayers of alkyl monophosphonic acids (monoPAs) for transfer printing efficacy. Water contact angle and AFM measurements indicated uniform films formed from both classes...
